Geophysical data to modeling soil properties in tropical hillslope areas. Author(s): CARVALHO JUNIOR, W. de 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... ... Repository: BDPA Publication year: 2022
Geoelectric method applied in correlation between physical characteristics and electrical properties of the soil. Author(s): NARCISO, M. G. 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... ... Repository: BDPA Publication year: 2017
Pedotransfer functions: the role of soil chemical properties units coversion for soil classification. Author(s): FONTANA, A.; TEIXEIRA, W. G. Chemical soil analysis data can be expressed by weight (i.e., gravimetric basis) or volume (i.e., volumetric basis) of the fine earth (sieved >=2 mm), resulting in different units, cmolc kg-1 and cmol... ...

Biochar as a soil amendment tool: effects on soil properties and yield of maize and cabbage in Brong-Ahafo Region, Ghana. Author(s): AKOLGO, G. A.; KEMAUSUOR, F.; AWAFO, E. A.; AMANKWAH, E.; ATTA-DARKWA, T.; ESSANDOH, E. O.; BART-PLANGE, A.; MAIA, C. M. B. de F. Ghana's soil is continuously declining in fertility due to continuous cultiva- tion and rapid mineralization of its soil organic matter. Previous studies have touted the potential of biochar to help i... ... Repository: BDPA Publication year: 2020
Soil classes and properties explain the occurrence and fruit production of Brazil nut. Author(s): SILVA, L. M. da; WADT, L. H. de O.; SILVA, K. E. da Soil properties and classes can influence the occurrence of plants and the production of Brazil nut fruits and may have a different distribution between sites. This study aimed to evaluate the relatio... ... Repository: BDPA Publication year: 2021
Soil physical, chemical and biological properties in Conilon coffee intercropping systems. Author(s): PEZZOPANE, J. R. M. Shaded coffee systems may offer a series of benefits, however, studies on shaded cultivation of Conilon coffee crops are still scarce in the literature. This study aimed to evaluate the soil physical,... ... Repository: BDPA Publication year: 2024
Unsaturated hydraulic property measurements of subtropical anthropogenic (purple) soils in China. Author(s): TEIXEIRA, W. G. Many anthropogenic soils, often referred to as red bed or purple soils, are distributed in various areas of southern China. Purple soils typically are highly weathered and often lead to natural and en... ... Repository: BDPA Publication year: 2024
Spatial variability of crop and soil properties in a crop-livestock integrated system. Author(s): ANDRADE, R. G.; BERNARDI, A. C. de C.; GREGO, C. R.; INAMASU, R. Y.; RABELLO, L. M.; VAZ, C. M. P. The knowledge of spatial variability soil properties is useful in the rational use of inputs, as in the site specific application of lime and fertilizer. The objective of this work was to map and eval... ... Repository: BDPA Publication year: 2010
Agricultural management systems affect on physical, chemical and microbial soil properties. Author(s): LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.; ALOVISI, A. M. T.; MARCHETTI, M. E.; CORTEZ, J. W. 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... ... Repository: BDPA Publication year: 2016
Spatial variability of vegetation index and soil properties in an integrated crop-livestock system. Author(s): BERNARDI, A. C. de C.; GREGO, C. R.; ANDRADE, R. G.; RABELLO, L. M.; INAMASU, R. Y. 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... ... Repository: BDPA Publication year: 2017
