Soil Fertility & Health

Soil fertility is commonly misinterpreted as the amount of nitrogen, potassium, phosphorous and microelements quantity in the root zone depth of soil. But in reality, it is defined as the ability to mobilise nutrients quickly, scientifically known as soil's cation exchange capacity (CEC). CEC of the topsoil that can be used to feed food crops like rice can be considerably increased by adding organic fertiliser and increasing the organic matter content (OMC) that will facilitate the plant to absorb available nutrients from the soil straight away without any obstruction or fixation and finally resulted in fairly high rice yield production while minimising the yield gap.
