Question

write a note on manure and fertilizers and explain how they improve soil fertility​

Answer 1

Answer:

Manure is a natural substance obtained by the decomposition of animal wastes which supplies essential elements and humus to the soil to make it fertile.

A chemical fertilizer is a salt or an organic compound containing the necessary plant nutrients like Nitrogen, Phosphorus and Pottasium. Both Manures and Chemical fertilisers help in boosting the growth of a crop by supplying the soil with adequate nutrients for plant growth. Please keep in mind that Manure is not always able to supply enough nutrients so Chemical fertilisers come in handy.
