Correction of resistance to penetration by pedofunctions and a reference soil water content. Author(s): MORAES, M. T. de; DEBIASI, H.; FRANCHINI, J. C.; SILVA, V. R. da ABSTRACT: The soil penetration resistance is an important indicator of soil compaction and is strongly influenced by soil water content. The objective of this study was to develop mathematical models... ... Repository: BDPA Publication year: 2012
Analyzing spatial and temporal variability of soil water content. Author(s): VIEIRA, S. R.; GREGO, C. R. TOPP, G. C. Durante as últimas duas décadas métodos geostatísticos têm sido intensamente adotados para descrever a variabilidade espacial em profundidade. O objetivo deste estudo foi avaliar a variabilidade espac... ... Repository: BDPA Publication year: 2008
Spatial Relationships Between Soil Water Content and Hydraulic Conductivity in a Highly Structured Clay Soils. Author(s): VIEIRA, S. R.; GREGO, C. R.; TOPP, G. C.; REYNOLDS, W. D. The water, element essential for life, is present as a large reservoir in the soil. Soil water content varies in space as a consequence of the variability of other related properties and its study is... ... Repository: BDPA Publication year: 2014
Soil penetration resistance in a rhodic eutrudox affected by machinery traffic and soil water content. Author(s): MORAES, M. T. de; DEBIASI, H.; FRANCHINI, J. C.; SILVA, V. R. da ABSTRACT: Soil compaction caused by machinery traffic reduces crop yields. This study aimed to evaluate the effects of intensive traffic, and the soil water content, on the soil penetration resistance... ... Repository: BDPA Publication year: 2013
Modeling the influence of water content and bulk density on soil penetration resistance. Author(s): VAZ, C. M. P.; MANIERI, J. M.; MARIA, I. C. de; TULLER, M. Repository: BDPA Publication year: 2010
Nitrate and ammonium content in percolated water after successive application of swine manure in soil cultivated with soybean. Author(s): MENEZES, J. F. S.; SILVA, M. P. da; BENITES, V. de M.; RIBEIRO, R. de L.; LEITE, A. K. F. The objective of this study was to determine the amount of percolated water per day and the levels of ammonium and nitrate leachate during soybean cultivation, based on precipitation and fertilization... ...
