Degradação de palhada e liberação de nitrogênio por plantas de cobertura sob plantio direto
(Revista Caatinga, 2014-01-01) [Artigo]
Crops used to cover the ground may also release nitrogen into the soil during mineralization. However, it is necessary to identify species that combine fast nutrient release and longer permanence of the straw on the soil ...
Adubação silicatada no sulco e nitrogenada em cobertura no arroz de sequeiro e irrigado por aspersão
(Bioscience Journal, 2014-01-01) [Artigo]
The objective of this work was to evaluate the effects of silicon application adjusted with nitrogen fertilization via top-dressing on grain productivity, the silicon contents of the soil, in the plant tissue and nitrogen ...
Produtividade de arroz de terras altas em função de reguladores de crescimento
(Revista Ceres, 2014-02-01) [Artigo]
The use of sprinkler-irrigation and/or high levels of fertilization in upland rice can increase plant height and hence plant lodging. Lodging can be controlled by using growth regulators, in order to reduce plant height. ...
Atividade da enzima nitrato redutase em cultivares de arroz de terras altas
(Agrarian, 2014) [Artigo]
The cultivation of upland rice seems to be, among the major crops, the least adapted to the notillage system (NTS). One of the reasons attributed to this lower adaptation to NTS would be the low activity of the nitrate ...
Nitrification inhibition in tropical soil under no tillage system
(Revista de Ciências Agrárias, 2014) [Artigo]
In no-tillage systems (NTS), biological activity and nitrification process in the soil are higher due to higher organic matter and moisture contents, resulting in higher levels of nitrate compared with areas under conventional ...
