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
Soil chemical attributes relationships around the Araucaria Angustifolia trees in agroforestry systems. Author(s): GOMES, J. B. V.; BOTOSSO, P. C.; LONGHI-SANTOS, T. 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
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
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.; VIEIRA, S. R.; XAVIER, M. A. 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
Influence of the physical, chemical, and hydric attributes of soils and leaf area on degradation levels of cultivated pastures. Author(s): SILVA, C. DE O. F.; RODRIGUES, C. A. G.; GREGO, C. R.; QUARTAROLI, C. F. Understanding the predominant factors that explain pasture degradation is crucial for developing reliable and feasible restoration plans. This article describes a multivariate analysis used for detect... ... Repository: BDPA Publication year: 2024
Influence of limestone and gypsum application on chemical attributes of dystrophic yellow latosol soil and corn yield in Eastern Amazon. Author(s): COSTA, S. D. A. da; BRASIL, E. C.; SILVA JÚNIOR, M. L. da The objectiveof this study was to evaluate changes in the chemical attributes of the soil caused by the use of limestone associated or not to with gypsum in no-tillage system. The experiment was condu... ... Repository: BDPA Publication year: 2020
Functional analysis of soil chemical attributes using Geographic Information Systems to assess nutrient deficiencies. Author(s): BARBOSA NETO, M. V.; ARAÚJO, M. do S. B. de; ARAUJO FILHO, J. C. de; SILVA, C. B. da; SAMPAIO, E. V. de S. B. Information on soil fertility is essential to determine the need for correcting measures. However, the use of appropriate techniques to provide information on the specific potential of each soil in ma... ... Repository: BDPA Publication year: 2022
Soil hydrophysical and chemical attributes in ferralsol amended with wood biochar. Author(s): LUCON, I. M.; CARNIER, R.; COSCIONE, A. R.; ANDRADE, C. A. de; JÚNNYOR, W. da S. G.; MARIA, I. C. de Abstract: Most studies concerning biochar, which can enhance chemical, physical, and biological soil qualities and increase crop yields, are short-term experiments in controlled environments with temp... ... Repository: BDPA Publication year: 2024
