RE: Choose your Country WiselyHow much potash is required per hectare per year??
For example...
Soybeans (along with most all other beans) remove 19.9 grams for everykilogram of soybeans removed. If you are trying to grow 3,600 kilograms perhectare then this results in 72 kilograms of potassium being removed perhectare. However, like corn, soybeans need more potassium than what is actuallyremoved to grow as a healthy plant. For this example, a farmer should apply 130kilograms of potassium per hectare.
Corn removes 4.2 grams of potassium for every kilogram of corn grainproduced. Suppose you are trying to grow 10,000 kilogram per hectare corn.This crop would remove 42 kilograms of potassium, but to grow this crop youwould need to apply 100 kilograms of potassium per hectare.
Wheat (along with most all other cereal grains) removes 4.2 grams for everykilogram of wheat removed. If you are trying to grow 3,600 kilograms perhectare then this results in 15 kilograms of potassium being removed perhectare. However, like corn and soybeans, wheat needs more potassium than whatis actually removed to grow as a healthy plant. For this example, a farmershould apply 70 kilograms of potassium per hectare.
4 million hectares of arable lease lands in Ethiopia x 100kg per hectare =400.000 tons/ year
