1 Answer

Answer :

Manure improves the soil quality with added nutrients. Manure provides extra organic matter called humus to the soil and therefore increasing the water retention capacity of sandy soils and drainage in clayey soil. Manures reduces soil erosion. They provide food for soil friendly bacteria which are helpful in growing crops. Effects of fertilizers are: Fertilizers make the soil to become too dry and powdered and rises rate of soil erosion. The organic matter decreases by decreasing the porosity of soil hence, the plant roots do not get oxygen properly. The nature of soil changes either to basic or acidic.
