Épocas de aplicação de ureias associadas à de nicosulfuron em híbridos de milho
Autor: Heitor Franco de Sousa, Paulo César Timossi, Edésio Fialho dos Reis, Guilherme Braga Pereira Braz
Publikováno v: Agrarian, Vol 14, Iss 52, Pp 136-143 (2021)
A adubação nitrogenada próxima à da aplicação de nicosulfuron ainda é considerada uma preocupação na agricultura. Essa associação pode ocasionar redução no crescimento e produtividade final de grãos. A necessidade de estudo sobre essa a

Ammonia volatilization from enhanced-efficiency urea on no-till maize in brazilian cerrado with improved soil fertility
Autor: Eduardo Lopes Cancellier, Douglas Ramos Guelfi Silva, Valdemar Faquin, Bruno de Almeida Gonçalves, Leandro Lopes Cancellier, Carlos Roberto Spehar
Publikováno v: Ciência e Agrotecnologia, Vol 40, Iss 2, Pp 133-144 (2016)
ABSTRACT High nitrogen losses by ammonia volatilization are expected when urea is used as the source of N. The use of controlled-release urea and urease inhibitors are possible strategies to reduce such losses and increase nitrogen use efficiency. Th

Ammonia volatilization and yield components after application of polymer-coated urea to maize
Autor: Eduardo Zavaschi, Letícia de Abreu Faria, Godofredo Cesar Vitti, Carlos Antonio da Costa Nascimento, Thiago Augusto de Moura, Diego Wyllyam do Vale, Fernanda Latanze Mendes, Marcos Yassuo Kamogawa
Publikováno v: Revista Brasileira de Ciência do Solo, Vol 38, Iss 4, Pp 1200-1206 (2014)
A form of increasing the efficiency of N fertilizer is by coating urea with polymers to reduce ammonia volatilization. The aim of this study was to evaluate the effect of polymer-coated urea on the control of ammonia volatilization, yield and nutriti

Publikováno v: Revista Ceres, Vol 61, Iss 2, Pp 241-247 (2014)
As videiras em produção tendem a aproveitar pequena quantidade do N, derivado do fertilizante mineral, mesmo cultivadas em solos com textura arenosa e baixo teor de matéria orgânica, o que confere a esses solos baixa capacidade de fornecimento de

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 37, Iss 4, Pp 969-975 (2013)
In Brazilian agriculture, urea is the most commonly used nitrogen (N) source, in spite of having the disadvantage of losing considerable amounts of N by ammonia-N volatilization. The objectives of this study were to evaluate: N lossby ammonia volatil
