Biological soil properties in integrated crop-livestock-forest systems. Currently, agricultural productivity and sustainable development are the desired bases for the creation of production systems. Farming for greater production and the efficient use of soil resources ar... ... Repositório: BDPA Ano de publicação: 2017
Geoelectric method applied in correlation between physical characteristics and electrical properties of the soil. This paper presents the study of the relationship between electrical properties and physical characteristics of the soil. Measures of apparent electrical resistivity of the soil were made for differen... ... Repositório: BDPA Ano de publicação: 2017
Agricultural management systems affect on physical, chemical and microbial soil properties. The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried... ... Repositório: BDPA Ano de publicação: 2016
Spatial variability of vegetation index and soil properties in an integrated crop-livestock system. ABSTRACT - The knowledge of soil property spatial variability is useful for determining the rational use of inputs, such as the site-specific application of lime and fertilizer. The objective of this... ... Repositório: BDPA Ano de publicação: 2017
Land-use type effects on soil organic carbon and microbial properties in a semi-arid region of Northeast Brazil. ABSTRACT - Land-use change is one of the most important anthropogenic environmental change drivers affecting the biodiversity and functioning of ecosystems. However, there is limited knowledge of the... ... Repositório: BDPA Ano de publicação: 2016
Changes in soil properties under two different management systems in the Western Amazon. Upland soils in the Amazon basin are often highly weathered and therefore possess low plant-available nutrient contents. Soil fertility is principally maintained by geochemical, biochemical, and bioge... ... Repositório: BDPA Ano de publicação: 2011
Geophysical data to modeling soil properties in tropical hillslope areas. Aero geophysical data is becoming an important source of environmental covariate in digital mapping. Airborne gamma-ray spectrometry is more common in digital soil mapping, because of the penetration... ... Repositório: BDPA Ano de publicação: 2022
Soil chemical properties in banana crops fertigated with treated wastewater. Determining the effects of using wastewater as fertilizer on soil chemical properties allows a safe reuse of this effluent in agriculture. This study evaluated the effects of fertigation with tertiary... ... Repositório: BDPA Ano de publicação: 2019
Soil chemical properties affected by cover crops under no-tillage system. The use of cover crops in no-tillage systems (NTS) can significantly improve the soil?s fertility. Thus, a study was performed to evaluate changes in chemical properties of soil caused by cover crops... ... Repositório: BDPA Ano de publicação: 2015
Effect of alternative multinutrient sources on soil chemical properties. O custo atual do cloreto de potássio relacionado à grande dependência de sua importação para suprir a demanda nacional sugere a necessidade de estudos que procurem avaliar a eficiência de fontes alter... ...
