Use of residual powder obtained from organic waste to partially replace cement in concrete
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
The main objective of this research is to investigate the feasibility of using the residual powder obtained from organic waste to replace a part of Portland cement during concrete production. The chemical and physical ...
Maize consumption in pre-Hispanic south-central Andes: chemical and microscopic evidence from organic residues in archaeological pottery from western Tinogasta (Catamarca, Argentina)
(Elsevier, 2015-03)
Pre-Hispanic Andean societies depended economically on the cultivation of maize (Zea mays), the main staple food crop in the region after its introduction from highland Mexico. Here we report new data from residue analysis ...
Impact of Crop and Residue Management on the Physical and Chemical Stabilization of Soil Organic Matter at Farm Level
(University of Nebraska, 2011)
This dissertation explores changes over time in soil organic matter (SOM) stabilization of two irrigated production fields: a continuous maize sequence that was converted from no-till to conservation deep tillage (Site 1), ...
Qualidade e quantidade de resíduos culturais modulam a estabilização de carbono e nitrogênio no solo
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2023-03-31)
Crop residues left on the soil surface play an important role in controlling erosion,
nutrient cycling and soil organic matter (SOM) formation. The diversification of
cropping systems is a strategy that allows the input ...

Harvest systems and residue management of sugarcane
(Empresa Brasil Pesq Agropec, 2005-03-01)
The use of sugarcane harvesting without residue burning is a common harvesting management in Brazil. The objective of this work was to evaluate the effect of harvest systems and management of sugarcane with and without ...
Characterization and thermal study of organic extracts of urban solid waste
(2014)
The urban residues put in landfill of the city of Sa˜o Carlos-SP, Brazil, in 2004 represent 58.7 % of decomposed organic material. The aim of this research was to characterize samples of urban solid waste and its organic ...
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 MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 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 ...
