Fertile soil is essential to obtain a better harvest from food crops. Rain and crop production remove large quantities of elements from soil and make soil unfertile. It also causes a decline in soil pH and makes nutrients unavailable to plants. On the other hand, accumulation of some elements brought about by indiscriminate use of agrochemicals and fertilizer enhances nutrient accumulation and causes difficulty in absorbing certain nutrients by plants. Deficiency in plant nutrients result in weak and stunted plants.
