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.
About 45% of local fields of this crop get it.
-
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.
About 45% of local fields of this crop get it.
-
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.
Few local farmers add it to this crop, so it's an easy place to get ahead.
-
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.
Few local farmers add it to this crop, so it's an easy place to get ahead.
What local farmers put on it (share of fields):
- Di-Ammonium Phosphate (DAP) 45%
- Urea 9%
