Question

If soil of a land is less fertile and farmer wants to cultivate a crop on this land then which of the following agricultural practices should be done by him to increase the fertility of soil as well as yield of crop?

(a) Adding excessive amount of fertilizer to the soil
(b) Adding manure to the soil
(c) By using crop rotation method
(d) Cultivation of weeds on that land along with crop

Answer 1

Adding manure to compacted soil helps loosen the soil. It enhances water-holding capacity of soil, promotes aeration and drainage, decreases soil loss by erosion, conserves moisture and prevents nutrient leaching and granulation, which help the plant growth. Crop rotation improves the physical and chemical conditions of soil and thus improves the overall fertility.
