:
B
∙ Manures are the organic substances obtained by the decomposition of animal excreta and plant waste. Adding manure is a natural way of increasing soil fertility and in turn increasing yield.
∙ Fertilisers are artificially synthesised inorganic salts which also increase yield. Excessive use of fertilisers kill the micro-organisms present in the soil. They runoff into the nearby water bodies which would result in water pollution.
