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 fertilizer (15 N) leaching in a central pivot fertigated coffee crop

Bortolotto, Rafael Pivotto; Bruno, Isabeli Pereira; Reichardt, Klaus; Timm, Luís Carlos; Amado, Telmo Jorge Carneiro; Ferreira, Ademir de Oliveira (Universidade Federal de Viçosa, 2012-07)

Nitrogen has a complex dynamics in the soil-plant-atmosphere system. N fertilizers are subject to chemical and microbial transformations in soils that can result in significant losses. Considering the cost of fertilizers, ...
Soil profile internal drainage for a central pivot fertigated coffee crop

Bortolotto, Rafael Pivotto; Bruno, Isabeli Pereira; Dourado-Neto, Durval; Timm, Luís Carlos; Silva, Adilson Nunes da; Reichardt, Klaus (Universidade Federal de Viçosa, 2011-11)

Coffee cultivation via central-pivot fertigation can lead to fertilizer losses by soil profile internal drainage when water application is excessive and soils have low water retention and cation adsorption capacities. This ...
