How the soil score worksMoney

Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

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 phosphorus Your soil is likely short of phosphorus.
Add about a quarter more DAP or single super phosphate than the usual dose, at sowing.
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 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.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of iron Your soil is likely short of iron.
Spray ferrous sulphate, 5 g per litre of water, when young leaves turn yellow.
