Sequestration of native soil organic carbon and residue carbon in complex agroecosystems
(Taylor and Francis Ltd., 2016-11)
Knowing short-term gains and losses of soil organic carbon (SOC) is crucial for understanding the role of different land management practices in climate change mitigation. This study evaluated the flow of carbon (C) in ...
For how long does the quality and quantity of residues in the soil affect the carbon compartments and CO2-C emissions?
(2016-10-01)
Purpose: The mineralization/immobilization of nutrients from the crop residues is correlated with the quality of the plant material and carbon compartments in the recalcitrant and labile soil fractions. The objective of ...
Phosphorus Fractionation in Soil Cultivated with Sugarcane Fertilized by Filter Cake and Phosphate Sources
(2015-10-28)
Studies of phosphorus (P) forms in high-weathering soils, after long periods of phosphate fertilizer application associated with organic residues, are important to optimize P fertilization. This study aims to evaluate the ...

Soil fertility and nutritional status of 'Ponkan' mandarin under solid organic residues and chemical fertilizationFertilidade do solo e nutrição de tangerineiras 'Ponkan' manejados com resíduos sólidos e adubação química
(2011-01-01)
The objective of this research was to evaluate some soil chemical attributes and the nutritional status of 'Ponkan' mandarin managed with organic residues and chemical fertilization. The experiment was carried out at the ...
Heavy Metals Extracted by DTPA and Organic Acids from Soil Amended with Urban or Industrial Residues
(Taylor & Francis Inc, 2013-12-16)
Understanding soil responses to the application of urban or industrial residues is necessary. In the current experiment, both sources of residues were applied to the soil surface of a Hapludox soil for 8 years. The four ...
