CROSS REFERENCE TO THE RELATED [0007 ] Water dispersible granules as such have been dis APPLICATION ( S ) closed in U . S . Pat. No . 8 , 241, 387 and WO2012131702 have [ 0001 ] This application claims priority from India Patent been known for a very long time. While these granules Application Nos . 201721016449 filed May 10 , 2017 ; instantly provide the nutrients , these granules have a poor 201721021720 filed Jun . 21, 2017 , and 201721024425 filed attrition resistance, and practically no hardness . While these Jul . 11 , 2017 , the contents of which are incorporated herein documents discloses granules in the size range of 0 . 1 mm to by reference in their entirety . 2 . 5 mm and 0 .75 mm to 5 mm , respectively, it is observed that the granules actually do not retain their integrity , 2 . FIELD OF THE INVENTION including their size and shape , and have no mechanical strength to withstand post production handling , and break [0002 ] The invention relates to an agricultural granular down to a fine dust. It has been observed that attrition caused composition . More particularly , the invention relates to a during production , packaging, storage , handling and appli water disintegrable granular composition , which includes at cation of these granules or powders leads to a premature least one agrochemical and one or more agrochemically breakdown of these compositions resulting in substantial acceptable excipient. The agrochemical is selected from a loss of release control, and excessive nutrient leaching . crop nutrient or algae or pesticidal active ingredient. The Furthermore , one of the biggest problems and challenges water disintegrable granular composition particularly has a with these water dispersible granules is their application and particle size of 0 . 1 microns to 50 microns , a bulk density of dependence on labour. When applied through mechanical less than 1 . 5 gm /ml and hardness of at least 1 Newton . applicators (hoppers and drillers ), such compositions get Furthermore, the invention relates to a process of preparing released at one location and cannot be distributed uniformly the water disintegrable granular composition including one through mechanized means . Farmers typically apply mix or more water insoluble nutrients or algae or the pesticidal tures of fertilizers in a single application . However , due to active ingredients . The invention further relates to a method their form , these water dispersible granules need to be of treating the plants or the soil with the water disintegrable applied separately from other granular fertilizers such as granular composition . urea . This makes it cumbersome for application and 3 . DESCRIPTION OF THE RELATED ART increases the cost of application for the farmer . [ 0008 ] Moreover, both powder and granular formulations [ 0003] Crop nutrients or fertilizers and pesticides have further tend to leach away , due to their instant and complete been applied to the soil for several years. They have been available in well known granular forms, such as prills , water dispersibility in water . (See Column C , FIG . 5 ) dispersible granules, or wettable powders , pastilles contain [0009 ] Pellet compositions of crop nutrients are also ing bentonite . known, such as those formed with bentonite clay. Brimstone [ 0004 ] A large problem with several crop nutrients or 90 , Tiger 90 , Growmor, Vitsul, etc . are some of the tradi fertilizers , which when applied , rapidly leach through soil, tional brands available in the market . However, these pellets due to either their rapid mobility in the soil or their physical have a higher bulk density , high particle size and do not form and characteristics . Leached nutrients may contribute disperse or disintegrate well when applied to the soil. They to groundwater contamination in regions with intensive also , do not provide nutrients when required by the crop . agriculture . In humid climates, some nutrient leaching These pellets take a long time to be assimilated in the soil or occurs even under natural vegetation , but agricultural activi at times remain as a whole or in the form of residues within ties can greatly increase leaching losses . the soil even after the crop has been harvested . As a result , [0005 ] It is estimated in one study of sandy soils that they do not provide adequate amount ofnutrients to the crop , leaching losses of sulphur amounted to 35 kg/ ha to 83 kg /ha thereby hampering crop nutrition during the early and grow depending on the various types of sulphur used during ing periods. Furthermore , these compositions are also application . It is also known that a shortage of sulphur in the required to be applied at very high dosages of application . In soil lowers the utilization of the available soil nitrogen , the end , the use of these traditional pellets results in lower thereby increasing nitrate leaching ( Likkineni and Abrol, crop yields at high application costs to the farmer . 1994 ) . [0010 ) Furthermore , biological materials such as algae , [ 0006 ] It is therefore important to provide these nutrients bacteria and others are useful alternatives to chemical agents to the plant at the right stage for uptake and more so to make for improvement and maintenance of soil nutrients . Granular the nutrients available to the crops or the plant throughout formulations with exterior coating of biological materials the entire crop life cycle while also preventing or reducing are also known. WO2016113665 discloses pellets with a leaching of the nutrients after application . One of the great deformable core , a binder and an exterior coat . The coating est challenges in the application of known compositions is comprises two parts — the first coat comprises a biological providing adequate release of the actives or nutrients , and material , and the second coat comprises a particular dessi also ensuring that the active is available for plant uptake cant or binder. Thus , this entire granular composition owing
