Groundwater contamination by nitrates due to agriculture is one of the main environmental problems. Nitrate leaching is a complex physical process, influenced by many variables. However, simulating nitrate leaching through models is now possible.Nitrate leaching from soils can be due to fertilization excess, improper irrigation or land management. It can be due to climate variability as well. Modelling … [Read more...] about Simulating nitrate leaching: Modelling approach
