Changes in soil pH and phosphorus availability during decomposition of cover crop residues
(Taylor & Francis, 2017-03)
The aim of this study was to determine the effect of winter cover crop (CC) residues on soil pH and phosphorus (P) availability. Three incubation assays were performed in pots using two CC: vetch (V) (Vicia villosa Roth.) ...
Improving the Fluorescence Detectability of Polycyclic Aromatic Hydrocarbons for Evaluation of Workplace Environments of Cement Industries Processing Organic Residues
(TAYLOR & FRANCIS INC, 2008)
The burning of organic residues and wastes in furnaces of cement industries has been an attractive and lucrative approach to eliminate stocks of these pollutants. There is a potential risk for producing PAH in the workplace ...
Chemical modifications in solarized soil with addition of organic residuesModificações químicas em solo solarizado, com e sem incorporação de resíduos orgânicos
(2008-01-01)
The soil solarization is used in small properties as an alternative for control of phytopathogens and weeds, besides it also can affect the availability of some nutrients and phytotoxic elements in the soil. Thus, one ...
COMPARATIVE ASSESSMENT OF THE NUTRITIONAL STATUS FOR BARU (Dipterix alata) SEEDLINGS
(Centro Pesquisas Florestais, Ufsm, 2016-01-01)
To a successful revegetation process, besides improving the edaphic area conditions, seedlings must have good quality, which can be assessed by nutritional status. This research evaluated the foliar contents of N, P, K, ...

To a successful revegetation process, besides improving the edaphic area conditions, seedlings must have good quality, which can be assessed by nutritional status. This research evaluated the foliar contents of N, P, K, ...
Residue decomposition and fate of nitrogen-15 in a wheat crop under different previous crops and tillage systems
(Taylor & Francis, 2008-02-11)
Nitrogen (N) management may be improved by a thorough understanding of the nutrient dynamics during previous-crop residue decomposition and its impact on fertilizer N fate in the soil-plant system. An experiment was conducted ...
Carbono orgânico e carbono residual do solo em sistema de plantio direto, submetido a diferentes manejos
(2011-07-01)
The organic carbon is a major component of the soil organic matter, and its stock is influenced by the type of management system used. This study aimed to evaluate the effect of two cropping systems, with and without cover ...
