Generally, 2–3 sprays at … The soil application of Zn at 1.0 kg ha as Zn-EDTA (T7) recorded highest grain yield of 5.42 t ha, filled grain percentage of 90.2%, 1000-grain weight of 25.41 g and number of panicles m of 452. Leach with water containing a small amount of B. In certain occasions like prolonged drought, there is no scope to apply fertilizers to the soil for want of moisture. Plant Al-tolerant cultivars (IR43, CO 37, and Basmati 370) which accumulate less Al in their foliage and take up and use Ca and P efficiently in the presence of Al. However, during second year (2012) crop growth rate was found to be non -significant with respect to all the treatments. Polyfeed contains 19: 19: 19 NPK with 6 micro-nutrients like iron, manganese, boron, zinc, copper and molybdenum, while multi K contains 13: 0: 46 NPK. These fertilizers have no other impurities like sodium and chloride and they are 100 % nutrients and these nutrients are easily absorbed through the leaves. Farm yard manure/Compost: 10 to 15 cartloads. In such special circumstances these soluble fertilizers are must to protect the crop against hunger and this forms a compulsory act of crisis management. Zone 9 - Hill Zone Much of this land suffers from soil nutrient problems, which will need to be overcome if productivity is to be increased. paddy soils sulphate (SO 4)2) ions may be reduced to sulphide (S)2) resulting in the precipitation of the Cd and Zn sulphide minerals (Iimura et al., 1981; Chaney et al., 1996). Dip seedlings or presoak seeds in 2-4% ZnO suspension. Soil application of ZnSO4 was also compared in 2006. It also increases resistance to disease and strengthens the stems of cereal plants, thus reducing their tendency to lodge. Phosphorous: 50 to 60 Kg P2O5/Ha. New leaves do not unroll and the distal parts of leaves maintain a needle like appearance. For all the zinc sulphate buyers and sellers 2(3): 10-15 The experiment was conducted at Bangladesh Agricultural University, Mymensingh farm during 2004 Boro season to evaluate the effect of S and Zn on rice (cv. Linear regression studies indicated that grain yield of rice is significantly influenced by Zn content of grain, Zn content of straw and DTPA extractable Zn content of soil at the level of 95.96, 96.74 and 95.57%, respectively. Zn-EDTA was found to be better for growth and yield of rice among the two sources of Zn. For intensive irrigated rice systems, research priorities include understanding how soil nutrient supply is linked to cropping intensity, what pattern of nutrient supply is required to achieve the high yield levels needed to meet the needs of rice consumers in the next century, and how to improve congruence of nutrient supply and crop demand through management. Key word: Sulphur and Zinc, Growth, BRRI dhan29. They form not only part of integrated nutrients but are of low cost. These are photosynthetic prokaryotic microorganisms capable of fixing atmospheric nitrogen. (60 to 100 kg N/ha). In main field, apply 12.5 t of FYM or compost or green leaf manure @ 6.25 t/ha. Stunted plants, reduced tillering and sterility results in reduced grain yield. Carrier based bacterial inoculants are applied by the following methods. Essential for the transformation of carbohydrates. The present experiment shows that foliar application of zinc and boron results in increased grain yield and yield components of wheat, and thus is recommended to increase crop production.. 2009. A large proportion of the phosphatic fertilizer applied to soil is fixed by conversion into insoluble forms of phosphorus which is not available to plants. The function of zinc in plants is as a metal activator of enzymes. It mobilizes the phosphorus required by rice. Application of phosphobacteria to the soil as seed coating or as seedling dip. Stages of application: Narpala. The root portion of the seedlings required for an acre is dipped in the mixture for 5 to 10 minutes and then transplanted. Soil submergence causes decrease in zinc concentration in the soil solution. (1) Green Manuring Leaves develop chlorotic streaks on either side of the midrib. Critical LCC value varies with the type of paddy genotypes. Older leaves turn brownish red and purple colors develop in leaves. J.Soil .Nature. Do. An explicit conceptual framework must underlie field work in these variable environments, and simple simulation models were identified as essential tools for targeting experiments and pre-testing improved technologies. And the foliar application of Speciality fertilizers plays an important role in supplying the nutrients at critical stages of flowering and grain formation. 3. Older leaves of whole plants are yellowish green.Â, Old leaves sometimes all leaves become light green.Â. Foliar spray of Brassinosteriods 0.3 ppm at Panicle Initiation and Flowering stages increased the grain yield. The area of rice harvested in the world increased during the past 40 years by 41% but rough rice production has increased by 304% (IRRI 1991). Apply 25 kg of zinc sulphate with 50 kg sand before transplanting. M/s Shree Salasar Agro Industry - Offering Powder Unnatee Mono Zinc Sulphate Mono Hydrate Fertilizers, For Vegetable And Paddy Growers at Rs 73/kg in Kanpur, Uttar Pradesh. The highest yield of grain and straw was 5.42 and 7.31 tonnes/ha respectively in the treatment receiving 1.0 kg Zn/ha as Zn-EDTA (T 7) and recorded 37.56 and 43.33 % increase in yield over that of control during both the years. Provides only 50% nutrients to maintain good yield. It is having highest purity i.e., 95 %. 1.3.4 Sowing time rdThe usual sowing time in the Valley for paddy nursery is 3 week of April to middle of May. 2. It seems that majority of Indica varieties are adapted to relatively low levels of nitrogen in the region of 25 kg N/ha. Potassium enhances the ability of the plants to resist diseases, insect attacks, cold and other adverse conditions. For semi-dry rice, hardened seeds are treated with. Zinc availability may be related to climatic conditions. are the deficiency symptoms of zinc. Zinc application methods and timing had significantly pronounced effect on paddy yield. Zone 7- Southern Transition Zone Cowpea may be raised as an intercrop in dry seeded low land (semi-dry) rice by sowing 12.5 kg seed/ha along with rice to serve as a source of green manure. This insoluble and unavailable phosphorus remains unutilized by plants in soil. Do not apply large amounts of N to less responsive varieties. m of nursery area. Zinc sulfate injection: IV: Metabolically stable adults receiving TPN: 2.5 to 4 mg zinc/day Acute catabolic states on TPN: Additional 2 mg zinc per day is recommended. Zn chelates (e.g., Zn-EDTA) can be used for foliar application. Paddy requires the following essential nutrients for its normal development: Nitrogen, phosphorus and potassium are known as primary plant nutrients; calcium, magnesium and sulphur, as secondary nutrients; iron manganese, copper, zinc, boron, molybdenum and chlorine as trace elements or micro-nutrients. The recommended P is fully applied as basal. S-2 and ZSB-S-4) isolated from paddy soil were screened as efficient zinc solubilizing isolates (ZSB) and tested on different insoluble zinc compounds. K is applied in two equal splits viz., basal and active panicle initiation stages. The results further show that basal application of chelated-Zn (at 1.0 kg Zn/ha) significantly increased the yield of rice by 2.65, 13.40 and 6.90 % higher over that of split application of chelated-Zn (Zn at 0.5 kg/ha each one at basal and Z29 stage) basal and split application of ZnSO 4 (20 kg Zn/ha) respectively. Rice: Nutrient disorders and nutrient management. BRRI dhan29). Rusty brown spots on the panicles and poor grain formation. Rice crop removes 30-40 g Zn per tonne of grain. Leaves and culms become soft and droopy thus increasing mutual shading. It is mobile within the plant and promotes root development (Particularly the development of fibrous roots),tillering and early flowering. Regular application of farm yard manure (FYM)at 10-15 tonnes /ha if applied , it helps in mitigating deficiencies of all the micronutrients in long run. A greenhouse pot experiment including two Cd levels (0, 10 mg Cd/kg, as CdCl 2 ) combined with three S rates (0, 30, 60 mg S/kg, as Na 2 SO 4 ) was performed to investigate the effect of S application on uptake and allocation of Cd in wheat cultivated in paddy soil. Rice gave significantly higher yield as 25% in The elevated solubility of zinc (Zn) in acid sulfate paddy soils can limit rice production and pose a risk of environmental pollution. For direct seeded crop, the basal application should be done one week after sowing. Assess the average LCC values of 10 leaf samples. in paddy rice where zinc deficiency is often In the place of green manure, press-mud / composted coir-pith can also be used. Manufacturer of Micronutrients Product - Mangala Zinc Sulphate Heptahydrate, Mangala Zinc Sulphate Monohydrate, Mangala Magnesium Sulphate and Mangala S - 90 offered by Mangalaore Chemicals Fertilizer Limited, Bengaluru, Karnataka. It consists ZnSO 4 H 2O (Zinc Sulphate MonoHydrate). For short duration varieties, N is applied in three equal splits viz., basal, active tillering, and active panicle initiation stages. The subscripts of S and Zn represent the dose in kg ha -1 . Reduced number of spikelets and grain quality. Zone 4 - Central Dry Zone Significant increase was recorded in number of spikes m-2, grains spike-1, thousand grain weight, biological yield and grain yield with foliar application of nutrients. sulphate @ 0.5g + lime 0.5 g/liter of water and drench it after drainage of previous water. The Content of Zinc is 33 %. The treatments consist of control (water spray), spray at tillering (single spray) and/or spray at jointing (two sprays) and/or spray at boot stage (three sprays). Zone 8 - Northern Transition Zone Magnesium is an essential constituent of chlorophyll. One packet of the inoculant (200g) is sufficient to treat 10 kg of seeds. In the first year (2011) crop growth rate was higher in T 9 and it was significantly at par with T 8 at 60-90 days after transplanting (DAT) but at 90 DAT-harvest stage, T 9 showed significantly higher crop growth rate as compared to all other treatments. Leaves narrow, short, very erect ‘dirty’ dark green. Rice plant depends mainly for its nitrogen upon the decomposition of organic matter under anaerobic conditions and in the early stages of growth takes up nitrogen in the form of ammonia which is the stable form of nitrogen in submerged soils. Apply 25 kg of zinc sulphate with 50 kg sand before transplanting. Only 20-25 per cent of phosphorous is available to plants. Grow tolerant cultivars for low soil Fe availability. If the value is above the threshold value, there is no need for top dressing during that week. Brown spots on veins of lower leaf blades and leaf sheaths. Choose suitable plant spacing for each cultivar. Four packets of the inoculant is mixed with 20 kgs of dried powdered farm yard manure and broadcast in one acre of main field just before transplanting. It is possible that the amount taken up by paddy is equal to the amount of silicic acid present in the water the roots absorb, so that the greater the amount of water transpired, the greater their uptake of silica. Improves aeration in rice soils by stimulating activities of surface film of algae and bacteria. The seeds required for an acre are mixed in the slurry so as to have a uniform coating of the inoculant over the seeds and then shade dried for 30 minutes. Effect of precision land leveling and Zinc bioavailability: Water use, productivity and input use efficiency in transition from flooded to aerobic rice (Oryza sativa), Effects of zinc fertilization on grain yield and shoot concentrations of zinc, boron, and phosphorus of 25 wheat cultivars grown on a zinc-deficient and boron-toxic soil, Effect of split application of zinc on yield of rice (Oryza sativa L.) in an inceptisol, Response of wheat to foliar application of nutrients, Response of rice (Oryza sativa) to sulphur and zinc on coastal alluvials of Andhra Pradesh, Zinc deficiency. Leaves initially show dark green colour, later become bleached and turn yellow to pink and necrotic. K is applied in two equal splits viz., basal and active panicle initiation stages. However, the effect of S on Cd uptake in winter wheat cultivated in paddy soil is rarely reported. Pale greyish green interveinal chlorosis spreads from the tip to the leaf base. Foliar application can guarantee the availability of nutrients to crops for obtaining higher yield. The organic acids produced by phosphobacteria dissolve the insoluble (fixed) form of phosphorous in soil and make it available to plants. Andhra Pradesh. Coat seeds with oxidants (e.g., Ca peroxide) to improve germination and seedling emergence by increasing the supply of O. Use 2gm of Mahazinc per litre of water and spray 15 days after transplantation in Paddy crop. Death of growing points, but new tillers continue to emerge during severe deficiency. Tips become chlorotic. Leaves narrow, short, erect and lemon-yellowish green. It offsets the harmful effects of excess nitrogen in the plant. Addition of mineral P fertilizer is required when the rice plants root system is not yet fully developed and the native soil P supply is inadequate. Soil and climate databases will be important in this effort. It is enough to apply 12.5 kg zinc sulphate /ha, if green manure (6.25 t/ha) or enriched FYM, is applied. Plough when the soil is dry so that B accumulates in the topsoil. yield attributing parameters (effective tillers, grains panicle-1 and 1000 grain weight) and straw yield were maximum in N 150 in 4 splits i.e. Started with an initial capacity of 4,500 MTPA of Zinc Sulfate heptahydrate in 1990, we are one of the largest manufacturers of Zink Sulphate in India with 17,500 MTPA with our manufacturing facility at Muzaffarnagar, UP. 38.19 and 18.27 mg kg, respectively. Adjust the number of splits and timing of N applications according to the crop establishment method. Leaf base of younger leaves become chlorotic brown and blotches/streaks on lower leaves. Incorporate straw instead of completely removing or burning it. Biofertilizers are ready to use live formulates of such beneficial microorganisms which on application to seed, root or soil mobilize the availability of nutrients by their biological activity in particular, and help to build up the micro-flora and in turn the soil health in general. Vitamin and protein content of rice increased. Aids in root metabolism and helps in the utilization of proteins. Moreover, this is highly effective for treatment of the different variety of crops such as cereals, pulses, oilseeds, cotton, sugarcane, vegetables, fruits, potato, paddy and much more.

Apply 5-10 kg Zn ha-1 as Zn sulfate, apply 0.5 â 1.5 % ZnSO. Green manuring builds up soil structure and improves tilth. LCC critical value is 3.0 in low N response cultures. Bacterial biofertilizers are supplied as carrier based inoculants. to identify and recommend high zinc-efficient paddy genotypes under different water saving irrigation practices and zinc fertilization levels for zinc-deficient saline soils of semi-arid tropics. Nitrogen, the most important nutrient for rice, is universally limiting the rice productivity. Potash: 40 to 50 Kg KO/Ha. 95 ($19.95/Fl Oz) Save 5% more with Subscribe & Save . In summary, drainage, oxidation and potentially, acidification of paddy soils at the grain fill stage results in the rapid transformation of CdS and ZnS to phyto-available ‘Algalisation’ increases the nitrogen content of both grain and straw besides increasing soil fertility. Green Manuring Crops: Sanai, Dhaincha and Moong/Urad. Decreases tillering and increase spikelet sterility. Chlorosis of tips and margins of older leaves as initial symptoms. Post Tehsil District State 3 Contact Details. Iron is necessary for the synthesis of chlorophyll. Promotes formation of crumbs in heavy soils leading to aeration and drainage. 2008. In rainfed environments, nutrient demand is closely linked to water availability, and participants saw a need to characterize environments accoring to the different patterns of resource limitations. Orange-yellow interveinal chlorosis on leaves followed by leaf tip death and leaf margin scorch. Like wise in flooded conditions due to continuous rains fertilizers could not be applied to the soil. However, little attention has been paid to the ligand-controlled release of Zn in these soils. Yellowing of leaves in paddy indicates the deficiency of nitrogen, but it is difficult to decide the quantity of nitrogen to be applied based on the extent of yellowing. It is an activator of nitrite reductase and  many respiratory enzymes. Rapid correction of Mg deficiency symptoms is achieved by applying a soluble Mg source such as kieserite or Mg chloride. If deficiency symptom appears, foliar application of 0.5% Zinc sulphate + 1.0% urea can be given at 15 days interval until the Zn deficiency symptoms disappear. For medium and long duration varieties, N are applied in two equal splits viz., basal and active panicle initiation stages. White and rolled leaf tips of young leaves. Applying 15-20 kg S ha-1 gives a residual effect that can supply the S needed for two subsequent rice crops. It might also offer health benefits for people with age-related macular degeneration -- a chronic, progressive eye disease characterized by vision loss at the center of your field of vision. For correcting the zinc deficiency, 25-30 kg /ha sulphate is mixed with 25-30 kg of fine soil and broadcast in the whole field at the time of final ploughing. This is a summary of discussions and conclusions from a workshop on nutrient-use efficiency of rice cropping systems, held 13–15 December 1995 at the International Rice Research Institute, Los Baños, Philippines [Field Crops Research, Special Issue, 1998]. Phosphorus is particularly important in early growth stages. Silicon sources: BRRI Dhan 29). Such a system of concurrent growing of cowpea also reduces weed pressure in semi-dry rice. Phosphorus is remobilized within the plant during later growth stages if sufficient P has been absorbed during early growth. Ash from burnt straw heaps should also be spread over the field. Leaf tips dry out eight weeks after planting. application of Zn at 50 kg ZnSO 4 /ha and among the genotypes Sugandha Samba and RNR-2354 have recorded highest grain yield. These products are quick acting, even in cool soils and they are inexpensive. Three foliar applications of nutrients resulted in maximum number of spikes m-2, grains spike-1, thousand grains weight and biological yield. Availability of both soil and applied zinc is higher in upland soil than in submerged soil. Zn deficiency can also be corrected by spraying 0.5-percent zinc sulphate (at a per-hectare rate of 2.5 kg zinc sulphate and 1.25 kg unslaked lime dissolved in 500 litres water). All concentrations are given in weight-% and the solvent is water if nothing else is shown. Harbour N fixing bacteria, rhizobia in root nodules and fix atmospheric N In order to obtain maximum yield, transplanting of paddy should be completed between Here, an application of zinc sulphate of 62.5 kg/ ha once every 2–3 years is suggested. $19.95 $ 19. It can be applied to rice through seed or seedling or soil. Cool temperatures and a wet winter-spring season may result in zinc deficiency in plants, due to reduced microbiological release of zinc from organic matter and/or restricted root development. Although it has been shown that zinc applications can last several years, under severe zinc deficiency situations or in Zone 2 - North Eastern Dry Zone Carry out dry tillage after harvesting, to increase the rate of sulfide oxidation during the follow period. Nitrogen: 100 to 150 Kg/Ha. Apply gypsum in Ca deficient high pH soils,e.g., on sodic & high K soils. Water Source: Bore well. Calcium combines with pectin in the plant to form calcium pectate, which is an essential constituent of the cell-wall. 4.6 out of 5 stars 2,045. It is an important element for improving plant health and disease resistance. Select fully opened disease free new leaf i.e. Apply 5-10 kg Zn ha-1 as Zn sulfate, apply 0.5 – 1.5 % ZnSO 4 /ha as a foliar spray at tillering (25-30 DAT), 2-3 repeated applications at intervals of 10-14 days. Helps in production and movement of photosynthates to sink. Zinc Sulphate: 25 Kg/Ha. It is estimated that the world’s annual rough rice production must increase still further, from 519 million tons in 1990 to 758 million tons by 2020 if food production per caput is to be maintained (IRRI 1989). Organic Zinc Zink. This method is used for transplanted crops. Boron facilitates the translocation of sugars by forming sugar borate complex. Blanket recommendation (Kg/ha) â 150:50:50. Two packets of the inoculant is mixed in 40 litres of water. Home ; Search results for: 'Z zinc sulphate' Search results for: 'Z zinc sulphate' Stable adult with fluid loss from the small bowel: Additional 12.2 mg zinc/liter of small bowel fluid lost, or an additional 17.1 mg zinc/kg of stool or ileostomy output is recommended. Use acid-forming fertilizers, e.g., ammonia sulfate [(NH. Avoid applying excessive amounts of N fertilizer, which increases yield and total uptake of N and Si, but also decreases the Si concentration in straw because of excessive biomass growth. Reduced tillering and increased spikelet sterility. Our offered Zinc Sulphate Monohydrate is extensively used for curing mineral deficiency of the plants especially zincs. Yellowish brown spots between leaf veins, extending to the whole interveinal area. Flowering and seed setting may be retarded. The actual requirement of nitrogen by the crop can be correctly assessed by leaf colour chart. Apply lime on acid soils to raise pH and Ca availability. It is enough to apply 12.5 kg zinc sulphate /ha, if green manure (6.25 t/ha) or enriched FYM, is applied. The bio-fertilizers used for rice crop are azolla, Blue green algae, Azotobacter, Azospirillum, Phosphobacteria. Young leaves chlorotic or light green colored with the tips becoming necrotic. Deficiency of zinc in lowland rice occurs in near neural to alkaline soils, particularly in calcareous soils. Workshop participants reviewed current research in crop management and genetic improvement of rice, and concluded that increased rice production will depend on explicit considerations of nutrient supply. The S0Zn0 (control) had the lowest grain yield with 4.35 t ha -1 as well as the lowest straw yield with 5.47 t ha -1 . Plate assay The isolates were inoculated into agar medium containing 0.1% insoluble zinc compounds viz ZnO, ZnS and ZnCO 3. Read about company. A diet of 300–400 g cereals day−1will supply only 4–6 mg Zn day−1in the case of … 0.5 -1 t of biomass of azolla /ha is used for paddy in two ways either as green manure before transplanting, or as dual crop in 7 DAT. Severe Si deficiency reduces the number of panicles m. Si-deficient plants are particularly susceptible to lodging. Ammonium sulfate used as N source was better than rest of the sources. Soil application of 25 % excess of recommended N. Foliar application of Urea 1% at weekly interval till the symptoms disappear. Furthermore, it is necessary for the development of a good root system. In Tamilnadu LCC critical value is 3.0 in low N response cultures like White Ponni and 4.0 in other cultivars and hybrids. In Asia, where arable land is scarce and population pressure is high, most of the targeted production must come from existing rice land. Commence the assessment of the leaf colour with LCC at 14 DAT in transplanted rice or 21 DAS in direct seeded rice and continue up to flower initiation/heading at an interval of 7-10 days. Maximum grain yield was recorded for two foliar sprays which was statistically similar to that of three foliar sprays. Effect on yield is more pronounced when S deficiency occurs during vegetative growth. Plant B-toxicity tolerant varieties (e.g., IR42, IR46, IR48, and IR 54). Delay planting until pH has increased sufficiently after flooding (to immobilize Al). Fertilizing the crop during early vegetative growth promotes tillering leading to higher yield. For more rapid correction of Si deficiency, granular silicate fertilizers should be applied: Calcium silicate 120-200 kg/ha , Potassium silicate 40-60 kg/ha. Functions with enzyme systems involved in breakdown of carbohydrates, and nitrogen metabolism. 4 Details of Farm On Cu-deficient soils, apply CuO or CuSO. Area: 3.00 Acres. Under special conditions of drought and waterlogging, apply N as foliar spray. It also enhances the availability of phosphorus than chemical fertilizer on 40th day besides improving the C:N ratio of soils. Productivity of mechanically transplanted rice (Oryza sativa L.) as influenced by time of nitrogen a...

Brown leaf margins and brown necrotic spots on the tips of older leaves. They are the most effective means of increasing crop production and supplement nutrient supply in the soil, especially to correct yield-limiting factors. Plant roots take up their silica as silicic acid. third leaf from the top as index leaf in paddy plant for assessing the leaf colour and ten leaves to be selected from ten plants in the field. Fresh uprooted rice has poorly developed root systems with many black roots. Dark brown elliptical spots on discolored areas two to three weeks later followed by browning and drying up. Excess of this element tends to delay maturity. Coarse, sparse, dark brown to black roots. The recommended P is fully applied as basal. ducted during the rice seasons of 2005 and 2006 at the Indian Agricultural Research Institute, New Keywords Rice Urea Zinc-coated urea Delhi, to evaluate the relative efficiency of 0.5, 1.0, Zinc nutrition Zinc oxide Zinc sulphate 1.5 and 2.0% Zn as ZnSO4- or zinc oxide (ZnO)- coated ureas for rice. Necrosis of chlorotic areas during severe Al toxicity. Cultivar improvement for efficient nutrient use can complement agronomic approaches. Inoculation with Azospirillum promotes early tillering and also the growth of rice and significantly increases filling rate of grain and the grain weight per plant at harvest. It plays an essential part in the formation of starch and in the production and translocation of sugars, and is thus of special value to carbohydrate-rich crops. Relative crop growth rate shows non-significant results during both the years. Apply 25 % recommended dose of N and K as basal. A. Assess the intensity of leaf colour each time at a particular time by a particular individual. Water application and control treatments resulted in minimum number of spikes m-2 , grains spike-1 , thousand grain weight, biological yield and grain yield, during both of the growing seasons. Foliar spray of Urea (10 g/lit) + DAP (20 g/lit) + KCl (10 g/lit) at PI and 10 days later for all varieties. It has the potential to significantly decrease the susceptibility of certain plants to both biotic and abiotic diseases. A field experiment on agronomic biofortification with zinc and iron micronutrients in maize was carried out during kharif season of 2015 at Agricultural Research Station, Bailhongal. Dark brown necrotic lesions on leaf tips, Leaves often bluish green and chlorotic near the leaf tip. Take average of two if the leaf colour matches between two colour strips of the chart. If deficiency symptom appears, foliar application of 0.5% Zinc sulphate + 1.0% urea can be given at 15 days interval until the Zn deficiency symptoms disappear. The solubilization potential was assessed both qualitatively and quantitatively under in vitro conditions. For clay soils where root snapping is a problem, 4kg of Gypsum and 1 kg of DAP per cent can be applied at 10 DAS. Apply Fe (salts, oxides) on low-Fe soils to increase immobilization of H. Avoid continuous flooding and use intermittent irrigation in soils that contain large concentrations of S. Carry out dry tillage after harvest to increase S and Fe oxidation during the fallow period. These fertilizers provide nutrients to the plant by foliar application as these fertilizers are completely soluble in water. Rock phosphate broadcast before flooding when soil pH is low. It involves in cell differentiation and development since boron is essential for DNA synthesis. Here we quantified the rate of ligand-controlled Zn release in Thai acid sulfate paddy soils, using ethylenediaminetetraacetic acid as the extractant.
