The application of chemical fertilizers causes many environmental problems such as, the greenhouse effect. Chemicals (especially nitrogen) enter the surface water through surface runoff, causing water quality deterioration. In addition, some fertilizers are becoming scarce and expensive. So it is imperative for crop growers to achieve the highest crop yields with as little fertilizers as possible. To this end, here you will read more about the technologies that are being developed such as Variable Rate Control (VRC) and section control during the application of fertilizers.
