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 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.
