Question

What will happen if only one crop is grown repeatedly in the soil?

Answer 1

If only one crop is grown repeatedly in the soil, it loses its fertility and gets devoid of nutrients. For this reason crop rotation is an important procedure, so that the fertility of the soil is retained and there is no loss of nutrients. For example, after cultivation of wheat, the fertility of soil decreases and thus leguminuos crops like peanut, moong etc. are cultivated after its harvest. These leguminous crops restore the fertility of soil.
