GONZALEZ TORRES, Anselmo et al. Efficient use and apparent recuperation of nitrogen in fodder corn at different grounds. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.2, pp.301-309. ISSN 2007-0934.

Fertilization is the component of bigger influence in the production of fodder corn and nitrogen is the nutriment of bigger request and the more limitation for this cultivation. The correct recommendation of the dose of fertilization improves the efficiency of the fertilizers and it reduces the superficial and subterranean risks of water pollution. The objective of the present study was to evaluate the efficiency of use of nitrogen at two grounds of contrasting texture (clayey and sandy). The evaluated treatments were 0, 50, 175, 300 and 425 kg -1. The bigger moral values in the efficient use of I nitrogenate and the apparent recuperation of the I nitrogenate the elders at the ground came from clayey texture. With the increment in them dose of fertilization himself increase in the production of biomass but dismiye the efficient use of I nitrogenate as well as the apparent recuperation of the same increasing the potential risk of environmental contamination that way.
