Influence of Long-Term Fertilisation on Nitrogen Leaching

Effect of long-term fertilizer application in maize crop growing on chemical element leaching in Fluvisol

“…However, from the ecological point of view, the impact of the strength of anthropogenic load with nitrogen fertilizers can be assessed based on the established conditions for migration of chemical elements under one-meter soil layer. Many studies have documented that the chemical composition of lysimetric water depends on the natural conditions -geology and hydrology of the land, soil type and climatic conditions, the form and amount of fertilizer used, and the processes of weathering (Atanassov et al, 1985;Meissner et al, 2010;Stoichev, 1997;Stoichev et al, 1996;Zhao, 2010). It is estimated that the rate of weathering of various minerals is a function of export of dissolved chemical elements draining the soil profile and are determined by the mineral and chemical composition of soil forming rocks (Chadwick and Chorover, 2001;Taylor and Velbel, 1991;Yakubu and Ojanuga, 2013).…”
