ManageMent of IrrIgatIon and nItrogen fertIlIzers to reduce aMMonIa VolatIlIzatIon

In the summer growing season of 2009/10, in which the mean temperature of five days after fertilization was higher and rainfall lower, cumulative N volatilization losses were

Nitrogen application had a favorable effect on N concentrations in leaves and grains, Soil Plant Analysis Development (SPAD) chlorophyll meter readings and on grain yield, where

We evaluated urea-based N fertilizers treated with coating technologies, i.e., coating with boric acid and copper sulfate - UCuB (N = 44.6 %, B = 0.39 % and Cu = 0.16 %) and

Daily N-NH 4 + volatilization rate from the evaluated nitrogen fertilizers: U_Z-i, urea+zeolite incorporated; U_NBPT-i, urea+NBPT incorporated; U_S-I, urea+elemental

This study aimed to evaluate nitrogen losses by ammonia volatilization from stabilized, slow and controlled release urea and its absorption by maize grown under no-till in an

Various products have been developed to suit ammonia volatilization and enhance urea efficiency, thus creating ample innovation possibilities; the products include

Therefore, when planning for nitrogen fertilization, one should consider many factors, such as the cost of fertilizers and staff for fertilizer application and the fact that the use

O pensamento freudiano posiciona-se para além do isolacionismo disciplinar, toma para si uma argumentação filosófico-política, inscreve-se no que Merleau-ponty definiu
