Emissão de óxido nitroso e mineralização do carbono de plantas de cobertura e de dejetos suínos e bovínos em plantio direto de mamona
(Universidade Federal de Santa Maria, 2009-02-27)
The increase in the availability of nutrients to soil microorganisms, especially carbon (C) and nitrogen (N), through crop residues and animal slurries can increase
dioxide carbon (CO2) and nitrous oxide (N2O) emissions ...
Dinâmica do nitrogênio-15N de palha de arroz, soja e sorgo em dois solos de várzea
(Universidade Federal de Santa Maria, 2016-07-29)
The use of alternative crops to rice (Oryza sativa L.), such as soybean (Glycine Maxl.) and sorghum (Sorghum bicolor L.) in lowland areas changes the chemical characteristics of the straw returned to soil. Straw quality ...
Estabilização do carbono de resíduos culturais no solo com o uso de xisto retortado
(Universidade Federal de Santa Maria, 2014-01-31)
The impact of retorted oil shale (ROS) addition on the dynamics of carbon (C) of crop residues (CR) in the soil is little known. Under laboratory conditions, the present study aimed to evaluate the residual and immediate ...
Estabilização do carbono- 13C de resíduos culturais no solo afetada pela qualidade, manejo dos resíduos e teor de carbono do solo
(Universidade Federal de Santa Maria, 2020-08-28)
Crop residue quality and soil carbon (C) content influence the stabilization of C in the granulometric fractions of soil organic matter (SOM). However, little is known about the interactions between these factors and under ...
Transformações do carbono e do nitrogênio no solo e produção de aveia com o uso de dejetos de suínos em plantio direto
(Universidade Federal de Santa Maria, 2005-08-12)
The use of pig manure, especially of the deep-bedding manure, is not so often in the winter cover crops, preceding the summer commercial plantation. The aim of this study was to evaluate the carbon and nitrogen dynamics ...
Interação entre a qualidade de resíduos culturais e a textura do solo com a dinâmica do carbono
(Universidade Federal de Santa Maria, 2016-01-08)
The chemical quality of crop residues is considered the primary driver of the dynamics of
carbon and stabilization of soil carbon (C) from the crop residues (C-new) depend on the soil
texture. The aim of this study was ...
