Why does farmer need artifically to improve soil fertility?

Answer 1

This is an interesting question, but not for the reasons you might think. The issue might be why any farmer might wish to improve the fertility of his soil - the answer to which is obvious: because without action on his or her part, the soil is relatively unproductive, and action to improve the fertility makes the crops grow better. But the question contains two important words: need, and artificially.

Dealing with "artificially" first, the word could simply mean to improve the fertility by adding something to it, which could include, for example, straw or manure. But more likely, it means increasing fertility by adding chemicals. Then the answer to the question might be "because the soil is deficient in an important element such as biologically active nitrogen, potassium or phosphorous".

The word "need" is interesting because it might suggest that the farmer is forced by some external agency to try to improve soil fertility. The answer to the question might then be "because unless the yield is big enough he will default on his bank loan and the bank will repossess the farm". Or perhaps "because decades of misuse of the soil has reduced its natural fertility to the point where additional chemicals are needed."

It's important to frame the question correctly!

Answer 2

Farmers may need to use artificial methods to improve soil fertility if the soil is lacking essential nutrients for plant growth. This can be due to years of intensive farming depleting the soil nutrients. Artificial methods such as fertilizers can help replenish the necessary nutrients to ensure healthy crop growth and high yields.
