How to make it work
-
Short of nitrogen Your soil is likely short of nitrogen.
Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of organic carbon Your soil is likely short of organic carbon.
Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of sulphur Your soil is likely short of sulphur.
Use single super phosphate instead of DAP, or add about 100 kg of gypsum per acre before sowing.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of zinc Your soil is likely short of zinc.
Mix 10 kg of zinc sulphate per acre into the soil before sowing. One dose lasts two or three seasons.
