Define soil fertility.

1.	Define soil fertility.
Answer» Soil fertility is the inherent capacity of the soil to supply nutrients to plants in adequate amounts and suitable proportions. All productive soils are fertile, but all fertile soils need not be productive. The problems like salinity/ alkalinity, acidity, waterlogging, adverse climatic conditions, etc may cause fertile soils to be unproductive. Soil fertility is an index of available nutrients to plants.
