Question

what can cause a decrease in soil quality of farm land that is left without crops during some months every year

Answer 1

Answer:

Let the land lie fallow for a season

Explanation:

In Agriculture when a farmer has some problems with the quality of his soil due to continued planting all year round without allowing the soil rest, there seems to be loss of some of the nutrients that help crops grow and he is unable to grow crops on his field.

The best option is to allow the land low fallow with grasses and other plants growing and replenishing the soil.
