1. Microbiological Indicators of Soil Quality Under Native Forests are Influenced by Topographic Factors
Abstract: Several microbiological indicators of soil quality present high sensitivity, but little is known about the influence of topographic factors on them. This work aimed to evaluate variability of biological indicators of soil quality across a hillslope under native forest and the influence of topographic factors on them. Four positions on a hillslope w

2. BIOLOGICAL FERTILIZER AND COVER PLANTS ON SOIL ATTRIBUTES AND MAIZE YIELD
RESUMO O milho é uma importante cultura para a economia brasileira, porém, é produzido em sistema de monocultura, e por isso, torna-se necessário o uso de práticas conservacionistas de manejo do solo que favoreçam o desenvolvimento da cultura. O objetivo deste estudo foi avaliar os efeitos da adubação biológica e plantas de cobertura nas propriedade

3. Soil Microbial Biomass as an Edge Effect Indicator in Semi-Deciduous Seasonal Forest Fragments
ABSTRACT This work had the objective to evaluate the activity and microbial biomass of the soil as an indicator of edge effect in Semi-Deciduous Seasonal Forest fragments. Three fragments of different sizes (small, medium and large) located in the Southwest region of Bahia state were evaluated, in which three sampling ranges were defined in each, and soil sa

4. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

5. Soil quality indicators after conversion of “murundu” fields into no-tillage cropping in the Brazilian Cerrado
Resumo: O objetivo deste trabalho foi avaliar as alterações na qualidade do solo devido a diferentes tempos de adoção do sistema plantio direto em campos de murundus convertidos para agricultura, bem como identificar quais seriam os melhores indicadores para explicar essas alterações. O estudo foi realizado em Plintossolo Háplico, no Município de Por

6. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

7. Diversity of soil spiders in land use and management systems in Santa Catarina, Brazil
Resumo: A capacidade de dispersão das aranhas em áreas contíguas (Arachnida, Araneae) está ligada diretamente às condições de manejo do solo. Objetivou-se com o presente trabalho estudar o efeito do sistema de uso do solo (SUS) sobre a abundância e diversidade das famílias de aranhas edáficas, bem como a relação dessas com os atributos físicos e

8. Prediction of soil CO2 flux in sugarcane management systems using the Random Forest approach
ABSTRACT: The Random Forest algorithm is a data mining technique used for classifying attributes in order of importance to explain the variation in an attribute-target, as soil CO2 flux. This study aimed to identify prediction of soil CO2 flux variables in management systems of sugarcane through the machine-learning algorithm called Random Forest. Two differ

9. Soil Microbial Attributes Under Agroforestry Systems in the Cerrado of Minas Gerais
ABSTRACT The aim of this study was to evaluate the soil microbiological attributes of two Agroforestry Systems (AFS) in the city of Grão Mogol-MG considering two soil classes (Udox and Aqualf). Three composite samples were collected from the 0-5 cm soil depth layer. Each sample was subsequently divided into five replications to evaluate the carbon of soil

10. Microbiological Attributes of Soil Under Spontaneous Restoration
ABSTRACT The aim of this study was to evaluate the effect of vegetation on soil microbial activity during spontaneous restoration and the effect of remaining eucalypts on the restoration stage of reserve ranges installed in eucalypt plantations. The studied areas were in the following stages: initial restoration stage with and without remaining eucalypts; ad

11. Soil management of sugarcane fields affecting CO2 fluxes
ABSTRACT The harvesting system of green sugarcane, characterized by mechanized harvesting and no crop burning, affects soil quality by increasing the remaining straw left on the soil surface after harvesting, thus, contributing to the improvement of physical, chemical, and microbiological soil attributes, influencing CO2 fluxes. This study aimed to evaluate

12. Reclamation status of a degraded pasture based on soil health indicators
Pasture degradation is a concern, especially in susceptible sandy soils for which strategies to recover them must be developed. Microbiological and biochemical soil health indicators are useful in the guindace of soil management practices and sustainable soil use. We assessed the success of threePanicum maximum Jacq. cultivars in the reclamation of a pasture
