How to make it work
-
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 65% 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 boron Your soil is likely short of boron.
Mix 4 kg of borax per acre into the soil before sowing.
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) 65%
- Muriate of Potash (MOP) 65%
- Nitro Phosphate Potash 65%
