How does crop residue removal affect soil organic carbon and yield? A hierarchical analysis of management and environmental factors
(2015-10)
The current advancement of the bioenergy sector along with the need for sustainable agricultural systems call for context-specific crop residue management options – implying variable degrees of removal – across climatic ...
Long-term residue removal under tillage decreases amoA-nitrifiers and stimulates nirS-denitrifier groups in the soil
(Elsevier Science, 2021-01)
No-till in continuous corn (Zea mays L.) production helps to keep an important volume of residues on the soil surface, creating management challenges that could be alleviated by residue removal for bioenergy or animal use. ...
Dynamics and efficacy of sulfentrazone, flumioxazin, and isoxaflutole herbicides applied on eucalyptus harvest residues
(2020-07-01)
Eucalyptus harvests generate residues that remain on the soil and affect the efficacy of preemergent herbicides in the following planting cycle. The objective of this work was to evaluate the dynamics of flumioxazin, ...
Arsenic entrapment in reactive columns of residual soils
(American Society of Civil Engineers, 2013-06)
The purpose of this research is to evaluate the aptitude of two residual soils for the remediation of groundwater contaminated by arsenic (As). Batch and soil column tests were performed to evaluate removal of As from ...
ORGANIC RESIDUE AND PHOSPHORUS AS CONDITIONERS OF DEGRADED SOIL AND EFFECTS ON THE INITIAL GROWTH OF Dipteryx alata Vog.
(Centro Pesquisas Florestais, Ufsm, 2014-07-01)
In northwestern Sao Paulo State, it was established, in 1965, the hydroelectric station of Ilha Solteira (CESP) that produced extensive degraded areas, from where it was removed the soil superficial layers. For the ...

(2014-07-01)
In northwestern São Paulo State, it was established, in 1965, the hydroelectric station of Ilha Solteira (CESP) that produced extensive degraded areas, from where it was removed the soil superficial layers. For the ...
Increases in Potentially Mineralizable and Dissolved Organic Nitrogen in a Sandy Surface Soil Fertilized with Nitrogen are Greater with Lupin than Wheat Residues
(Springer, 2021-09)
Maintaining adequate nitrogen (N) supply to dryland cereal crops remains a critical management issue for optimizing productivity and N-use efficiency. Combinations of crop residue and fertilizer-N inputs can be used to ...
