13. Impact of different grazing systems for bovine cattle on the soil microbiological and chemical characteristics
The objective of this work was to study the effect of grazing systems: rotational, continuous and the absence of cattle, in pastures of Brachiaria brizantha on microbial activity (respiratory, potential nitrification, solubilizing, and enzymatic) and on the chemical attributes (contents of organic carbon, total nitrogen, organic phosphorus, and moisture) of

14. Atividade e diversidade catabólica da biomassa microbiana do solo alterada pelo uso da terra / Effects of soil land use on microbial activity and catabolic diversity
The increasing demand for food creates environmental problems, mainly due to the removal of native vegetation cover for agriculture expansion in Brazil. These changes in land use leads to changes in the soil organic matter dynamics. The vegetation type also affects the soil biota and, therefore, its change causes modifications in the microbial biomass, as sh

15. Atributos microbiológicos, físicos e químicos de solos na região oeste paulista / Microbiological, physical and chemical attributes of soil in the western region of São Paulo state
A fertilidade e a atividade microbiana em solo têm sido utilizadas com frequencia para indicar mudanças na qualidade do solo. A atividade microbiana interage diretamente com as condições ambientais, classes de solo e diferentes sistemas de produção agrícola utilizados. Apesar dos avanços nesta área ainda é um grande desafio a definição de bons in

16. SISTEMAS DE MANEJO E SUCESSÃO DE CULTURAS NA QUALIDADE DO SOLO NOS TABULEIROS COSTEIROS SERGIPANO / Systems management and succession of crops in soil quality in the Table Lands Sergipano
The region of the Table Lands Sergipano is characterized by intense intemperization, because the influence of the high regime of rainfall and conditions of high temperature, so that there are mainly changes in physical and chemical properties of soil. The search for productive and environmental sustainability in agroecosystems is necessary to measure indicat

17. Bioindicadores de qualidade de solo em diferentes ecossistemas
Changes due to soil management and cultivated plant species may influence carbon, nitrogen and phosphorus cycling. Cycling depends on the integration of physical, chemical and mainly microbiological processes. This work assessed some microbial activity and processes related to carbon, nitrogen and phosphorus cycles in soil from six ecosystems in Guarapuava,

18. Diversidade microbiana em solos sob florestas de Araucaria angustifolia / Microbial diversity in soils under Araucaria angustifolia forests
The Ombrophilic Mixed Forest, also called Araucaria Forest, represents one of the richest remainders of subtropical pluvial forests in Brazil. Its main representative species is the endangered Araucaria angustifolia. The microbial diversity plays an important role in functioning of forest ecosystems. However, the microbial diversity in soils with araucaria f

19. Microbiological soil attributes of a pasture area with surplus irrigation of wastewater effluent / Atributos microbiológicos do solo em área de pastagem irrigada com lâminas excedentes de efluente de esgoto tratado
Crop irrigation with treated sewage effluent (STE) is an interesting and attractive practice, when applied in a controlled manner, as well as it makes possible the release of water of better quality for other human activities and serves as a way to polish the STE through the "biological filter" comprising the soil-plant system. However, wastewater irrigation

20. Atributos químicos e microbiológicos do solo após aplicações de resíduos de suínos em sistema de plantio direto
Intensive rearing of swine livestock results in a huge amount of liquid residues (pig slurry), which can be a source of contamination to the environment. This residue contains phosphorus nitrogen and other nutrients; therefore it seems appropriate to use it on cropped soils as fertilizer. This work aimed to evaluate chemical and microbiological changes in th
