Phytomass addition and liming in the dynamics of soil chemical and physical attributes. Author(s): SILVEIRA, P. M. da; NASCENTE, A. S.; CARVALHO, M. da C. S. In tropical regions, a greater phytomass addition to the soil can help to improve soil quality. Additionally, the use of limestone is a fundamental practice in weathered soils of these regions. The ob... ... Repository: BDPA Publication year: 2019
Land-use effects on the chemical attributes of low-order streams in the eastern Amazon. Author(s): FIGUEIREDO, R. de O.; SCHULER, A. E.; WATRIN, O. dos S. The objectives of this study are to investigate chemical changes in stream water in response to land use change under the geologic and soil conditions of the eastern Amazon. We used an upstream-downst... ... Repository: BDPA Publication year: 2010
Physico-chemical attributes of a Cambisol under pasture managed with annual burns after sugarcane vinasse application. Author(s): FERREIRA, R. R. M. Purpose: Sugarcane vinasse is generated in large amounts and can be utilized to improve soil attributes, especially in areas degraded by burns. The aim of the present study was to evaluate the effects... ... Repository: BDPA Publication year: 2018
Soil chemical attributes relationships around the Araucaria Angustifolia trees in agroforestry systems. Author(s): GOMES, J. B. V.; BOTOSSO, P. C. This work aimed to understand the relationships between araucaria trees and some abiotic factors (soil type, soil organic C and soil nutrient supply) in agroforestry systems (AFS). Soils of two produc... ... Repository: BDPA Publication year: 2023
Evaluation of corn production parameters and their spatial relatioship with chemical attributes of the soil. Author(s): MARTINS, A. L. da S. The characterization of the soil spatial variability allows a better understanding of the relationships between the soil attributes and the environment. The objective of the study was to evaluate the... ... Repository: BDPA Publication year: 2011
Changes in chemical attributes of soil treated with tannery sludge in Amazonia. Author(s): TEIXEIRA, S. T.; WADT, P. G. S.; PEREZ, D. V.; BERTOTTI, F.; KLIMAS, C. Application of residuals to soil can favor the development of nutrient-poor agricultural areas. The objective of this study was to evaluate changes in the chemical attributes of soil after application... ... Repository: BDPA Publication year: 2017
Multivariate analysis of chemical and physical attributes of quartzipsamments under different agricultural uses. Author(s): SALVIANO, A. M.; GIONGO, V. The inadequate agricultural management in the semiarid region of northeastern Brazil, associated with the fragility of most soils, has caused degradation of the quality of this resource. This study ai... ... Repository: BDPA Publication year: 2019
Chemical attributes of a Hapludox soil after nine years of pig slurry application. Author(s): VEIGA, M. da; PANDOLFO, C. M.; BALBINOT JUNIOR, A. A.; SPAGNOLLO, E. ABSTRACT: The objective of this study was to evaluate the pig slurry application effects on chemical attributes of a Hapludox soil managed under no-tillage system. Treatments consisted of 50, 100 and... ... Repository: BDPA Publication year: 2012
Spatial variability of some biometric attributes of sugarcane plants (variety IACSP93-3046) and its relation to physical and chemical soil attributes. Author(s): GREGO, C. R. Tests to evaluate competition between plants, in general do not consider the soil spatial variability, nevertheless, the uniformity rarely is present and can not be assumed without verification. The a... ... Repository: BDPA Publication year: 2010
Chemical attributes and microbial activity of soil cultivated with cassava under different cover crops. Author(s): ARAÚJO, F. S.; BARROSO, J. R.; FREITAS, L. de O.; TEODORO, M. S.; SOUZA, Z. M. de; TORRES, J. L. R. Conservationist systems of crop management increases the amount of substrate, alters fertility and increases soil biological activity. The objective of this study was to evaluate the influence of soil... ... Repository: BDPA Publication year: 2019
