How to do soil treatment in Cotton crop?
  • After starting the cultivation process in cotton with deep ploughing, use a harrow 3-4 times so that the soil is friable and water holding capacity increases. By doing this, the harmful insects present in the soil, their eggs, pupa and the spores of fungi are also destroyed.
  • Soil treatment must be done so 4 kg of zinc solubilizing bacteria, 2 kg of Growmax (seaweed, amino acids, humic acid, and mycorrhiza), 2 kg of Trichoderma viride and 100 gm of NPK consortia bacteria in 4 tons FYM per acre mix well at the rate and spread it in the field.
  • By doing this, along with improving the structure of the land, complete development of plants and complete nutritional growth, it also protects against harmful soil-borne fungal diseases.
