Nitrate leaching through climatologic water balance in a fertigated coffee plantation

Bortolotto, Rafael Pivotto; Bruno, Isabeli Pereira; Dourado-Neto, Durval; Timm, Luís Carlos; Silva, Adilson Nunes da; Reichardt, Klaus (Universidade Federal de Viçosa, 2013-11)

Nitrate losses from soil profiles by leaching should preferentially be monitored during high rainfall events and during irrigation when fertilizer nitrogen applications are elevated. Using a climatologic water balance, ...
Nitrogen dynamics in a Latosol cultivated with coffee

Souza, José A.; Rocha, Genelício C.; Gomes, Mateus de P.; Rezende, Carlos H. S. (Departamento de Engenharia Agrícola - UFCG, 2018-06)

The objective of this study was to evaluate nitrogen losses by NH 3 volatilization and quantify the upward and downward NO 3- flows in Latosol cultivated with arabica coffee. An experiment was set in 2010, in Viçosa-MG, ...
Nitrogen loss by volatilization of nitrogen fertilizers applied to coffee orchard

Dominghetti, Anderson William; Guelfi, Douglas Ramos; Guimarães, Rubens José; Caputo, André Luiz Carvalho; Spehar, Carlos Roberto; Faquin, Valdemar (Editora UFLA, 2016-03)

Ammonia volatilization (N-NH3) is one of the main pathways of Nitrogen loss reducing nitrogen use efficiency in coffee orchard. This work aimed at quantifying ammonia volatilization (N-NH3) losses from N-sources to be used ...
