FARMING FOR CLIMATE CHANGE

It is a well-known fact that chemical fertilizers’ efficiencies are very low due to leaching, volatilisation and fixation. This contributes to low fertilizer efficiency (as low as 40-60% for nitrogen, 40-50% for potassium, and 30% for phosphorous). The most limiting factor today is microbial activity in the soil. Plant nutritionists must integrate plant nutrition and soil biology. Research has consistently shown that soil micro-organisms will increase the efficiency of applied fertilizers.

For every 1% increase in soil organic matter per hectare:
22-29 Kg of Nitrogen is available every year
5-7 Kg of Phosphate is available every year
2-3 Kg of Sulphur is available every year
234,000 Litres of available water
