Definitions

  • the present invention relates to a crop nutrient and fortification composition
  • a crop nutrient and fortification composition comprising elemental Sulphur, at least one trace nutrient selected from Selenium and Vanadium, and at least one agrochemically acceptable excipient; wherein the composition has particles in the size range of 0.1 micron to 30 microns.
  • the invention relates to a crop nutrient and fortification composition in the form of water dispersible granules or aqueous suspension comprising elemental Sulphur in the range of 1% to 90% by weight of the total composition; at least one trace nutrient selected from Selenium and Vanadium in its elemental form or salts or complexes or derivatives thereof wherein elemental Selenium or Vanadium content is in the range of 0.001% to 10% by weight of the total composition; and at least one surfactant selected from non-ionic and anionic surfactant in the range of 0.1% to 40% by weight of the total composition wherein the composition has particles in the size range of 0.1 micron to 30 microns.
  • the invention furthermore relates to a method for improving plant health, plant yield and enhancing the uptake of nutrient by the plants; wherein the method comprises treating at least one of a plant, a plant propagation material, locus or plant parts thereof, a seed, seedling or surrounding soil with the crop nutrient and fortification composition of the present invention.
  • the present invention furthermore relates to a method of treating plants and meeting their nutritional requirement by making the nutrients like sulphur, selenium and vanadium available to them and also unlocking other micronutrients and trace elements present in the soil which hitherto were not available because of various factors primarily being soil degradation or antagonism between the nutrients on account of excessive use of synthetic fertilizers.
  • fertilizers to supply nutrition to plants and prevent degradation of soil health has been an integral part of crop management.
  • excessive and indiscriminate application of fertilizers particularly chemical fertilizers like urea, DAP etc. can cause severe imbalance of soil pH and nutrient antagonism resulting in nutrient deficient produce.
  • environmental conditions such as drought, biotic and abiotic stress
  • soil health also impacts the yield and quality of produce.
  • leaching of nutrients during heavy rainfall not only leads to lack of availability of the same for uptake by plants but also lead to ground water contamination.
  • another challenge is addressing the nutrient antagonism when multiple macronutrients, secondary macronutrients, micronutrients and trace nutrients are involved in fertigation.
  • Sulphur is an essential plant nutrient, long known for its role as a fertilizer. Deficiency of Sulphur has become widespread over the past several decades in most of the agricultural areas of the world, resulting in Sulphur being indicated as a limiting factor to high yields and fertilizer efficiency.
  • One of the reasons of growing Sulphur deficiency in recent times being global guidelines towards usage of desulphurized fuel to meet strict emission standards resulting in lack of replenishment of soil Sulphur which was earlier met to a large extent on account of presence of atmospheric Sulphur being delivered in the form of rain water.
  • the other reasons for deficiency of Sulphur are unavailability of Sulphur in assimilable form to the plants, loss of Sulphur caused by leaching and soil pH, and insolubility of elemental Sulphur in water.
  • Selenium and Vanadium are the trace elements which are not considered to be indispensable for plants and this may be one of the reasons for unavailability of an effective commercial product that supplies these nutrients with high nutrient use efficiency.
  • Selenium is not essential for plant however, it is an indispensable trace nutrient required for balanced nutrition in animals and humans.
  • the primary source of Selenium in animals and humans is from diet, which in turn depends on the soil Selenium content and its bioavailability to crops.
  • Selenium deficiency affects about 500 million to 1 billion people worldwide due to inadequate dietary intake (NDA/BLA Multi-disciplinary Review and Evaluation NDA 209379, US FDA).
  • Selenium in humans have been linked to several kinds of cancer, heart disease and other chronic and life-threatening conditions (Gupta et. al, Selenium in soils and crops, its deficiencies in livestock and humans: Implications for management, Communications in Soil Science and Plant Analysis, 31:11-14, 1791-1807, 2000).
  • Selenium is considered a beneficial element for higher plants, enhancing the antioxidant metabolism, photosynthesis, secondary metabolites and carbohydrates in plant leaves.
  • Deficiency of Selenium in plants leads to stunted growth of plants and chlorosis of leaves.
  • the uptake of Selenium by plants is governed by various environmental factors such as soil pH and concentration of other competitive plant nutrients.
  • Vanadium is known for its dual role in environment as it may exert both beneficial and detrimental effects on plants and humans. Vanadium also stimulates functioning of antioxidants and helps in improved nutritional uptake of Phosphorous, Iron, Copper, Zinc and Molybdenum in plants. Deficiency of Vanadium in humans have been linked to growth retardation, bone deformities, and infertility, whereas deficiency of Vanadium affects the growth and yield of plants.
  • Selenium containing fertilizers comprises Selenium in combination with nitrogen fertilizers such as ammonium sulphate or lime nitrogen or urea or NPK fertilizers.
  • nitrogen fertilizers such as ammonium sulphate or lime nitrogen or urea or NPK fertilizers.
  • uptake of Selenium decreases with increasing use of nitrogen, such compositions do not make Selenium readily available for plant uptake.
  • powder compositions not only has issues with respect to a practical application like the generation of dust but also pose risk to the users mostly because of eye irritation, inhalation risk and skin irritation.
  • compositions are not easily dispersible and tend to clog the nozzles when applied via drip, making it unsuitable for use in irrigation system.
  • these compositions have also been found to have poor suspensibility which lead to random and non-uniform distribution of active ingredient on the target area which would cause undesirable effects and pose a problem in effective delivery of nutrients to the plant or crop, leading to poor uptake of the nutrition by the plants. Owing to such issues, these compositions are also required to be used in large amounts rendering them uneconomical and environmentally unsafe.
  • US 4,847,087 discloses the composition of Sulphur and Selenium for application to pasture land primarily to provide Selenium to herbivores gradually and over a longer period of time.
  • the composition is in the form of porous structure prepared by dissolving elemental Selenium into molten elemental sulfur, and cooling to form a solid solution.
  • the process of production of such products has a number of disadvantages. The most important disadvantage is the fire and explosion hazards. Another problem is non-uniformity of the size and shape of the particles of the composition, and slow release of Selenium resulting in poor efficacy in the field. More than that, molten elemental sulphur composition once solidified, do not release sulphur and the granules are found intact in the soil, sometimes even one season after harvesting the crop.
  • CN109453736 discloses multi-component composite attapulgite soil-conditioner obtained by adsorbing sulfur and calcium as calcium sulphate on attapulgite powder and mixing this with silica sol containing Selenium and zinc as zinc selenite which is gelled, granulated and dried to obtain the soil conditioner of the silicon-sulfur- Selenium-zinc multi-element composite having silica sol coating over the attapulgite powder.
  • Such type of granules having silica sol coating releases a small amount of nutrients and trace elements such as silicon, Selenium and zinc after high temperature calcination.
  • CN112321350 discloses soluble fertilizer containing sodium selenite, sulfur as sulphate, manganese sulphate, zinc sulphate, magnesium sulphate, calcium chloride, ammonium molybdate, alkylpolyglycoside, chitosan quaternary ammonium salt for foliar application.
  • Such type of compositions supplying Sulphur in sulphate form viz. calcium sulphate, ammonium sulphate etc. are not found to be very effective since such compositions tend to be leached away during heavy rainfall or irrigation and fail to be absorbed by the plants and this in turn also causes ground water contamination. As soils become more saline, plants are unable to draw as much water and nutrients from the soil. This results not only in a marked loss of efficiency but also has serious environmental consequences.
