Evaluate the effect of three levels pH in leaching and volatilization of nitrogen fertilizers, in three soil types
Scholars Research Library Der Pharma Chemica
The present study was realized in order to determine the type of soil and the suitability of pH to avoid the losses of nitrogen from leaching and volatilization, using three different soils: organic, clayish and sandy, pH: 6, 7 and 8 and four nitrogenous fertilizers: Urea, Ammonium sulfate, Ammonium nitrate and Potassium nitrate. The ammonium and nitrates were estimated by using a probe and an spectrophotometer. The present research was conducted in Agricultural Sciences Faculty (IASA I),fatcat:s3eqbp7dl5ferdv7mhkel2ecoi
