The use of chemical fertilizers in agriculture in the last few decades has led to a marked increase in agricultural production. The addition of chemical fertilizers to crops ensures that plants receive the correct formulation of nutrients that are necessary for growth. Plants will mature faster and produce more when this is done. Fertilizers also enable the use of agricultural lands to be ongoing as there is no need to rest the soil to allow nutrients to naturally build up. Growing can, therefore, be continuous all year round, leading to increased production.
