ABSTRACT The success of soil prediction by VIS-NIR-SWIR spectroscopy has led to considerable investment in large soil spectral libraries. The aims of this study were 1) to develop a soil VIS-NIR-SWIR spectroscopy approach using legacy soil samples to improve spectral soil information in a regional scale; (2) to compare six spectral preprocessing techniques; and (3) to compare the performance of linear and non-linear multivariate models for prediction of sand and clay content. A total of 1,534 legacy soil samples, stored […]

Effects of pig slurry application on soil physical and chemical properties and glyphosate mobility

Daniela Aparecida de Oliveira, Adilson Pinheiro, Milton da Veiga

01/Oct/2014

Pig slurry applied to soil at different rates may affect soil properties and the mobility of chemical compounds within the soil. The purpose of this study was to evaluate the effects of rates of pig slurry application in agricultural areas on soil physical and chemical properties and on the mobility of glyphosate through the soil profile. The study was carried out in the 12th year of an experiment with pig slurry applied at rates of 0 (control), 50, 100 and […]

Physical attributes of a Haplic Cambisol in vineyards subjected to different traffic intensities

Agricultural machine traffic causes soil compaction in vineyards, which may be accentuated between the rows due to greater intensity of traffic. The aim of this study was to evaluate the variability of soil physical properties as a function of the sampling position in relation to the plant row in commercial vineyards of the Bordô variety planted directly in the soil and subjected to different management practices. In February 2012, three vineyards were selected in the municipality of Major Gercino, southern […]

Paper-recycling waste application to an Inceptisol and its effect on soil and crop cultivation

Alvadi Antonio Balbinot Junior, Milton da Veiga, José Alfredo da Fonseca, Gilcimar Adriano Vogt, Jackson Adriano Albuquerque, Epitágoras Rodson Oliveira Costa

01/Feb/2014

The paper recycling process produces a large amount of waste and applying it on the soil may be one important strategy for use of this product. However, it is necessary to study the effects of application of this waste product on soil properties and crop performance. The aim of this study was to evaluate the effect of paper recycling waste on the chemical properties of an acidic Inceptisol and on the yield of soybean and common bean. A randomized complete […]

Tillage systems and nutrient sources affecting soil cover, temperature and moisture in a clayey oxisol under corn

Milton da Veiga, Dalvan José Reinert, José Miguel Reichert

01/Dec/2010

Tillage affects soil physical properties, e.g., porosity, and leads to different amounts of mulch on the soil surface. Consequently, tillage is related to the soil temperature and moisture regime. Soil cover, temperature and moisture were measured under corn (Zea mays) in the tenth year of five tillage systems (NT = no-tillage; CP = chisel plow and single secondary disking; CT = primary and double secondary disking; CTb = CT with crop residues burned; and CTr = CT with crop residues […]

Aggregate stability as affected by short and long-term tillage systems and nutrient sources of a hapludox in southern Brazil

Milton da Veiga, Dalvan José Reinert, José Miguel Reichert

01/Aug/2009

The ability of a soil to keep its structure under the erosive action of water is usually high in natural conditions and decreases under frequent and intensive cultivation. The effect of five tillage systems (NT = no-till; CP = chisel plowing and one secondary disking; CT = primary and two secondary distings; CTb = CT with crop residue burning; and CTr = CT with removal of crop residues from the field), combined with five nutrient sources (C = control, no […]

Short and long-term effects of tillage systems and nutrient sources on soil physical properties of a Southern Brazilian Hapludox

Milton da Veiga, Dalvan José Reinert, José Miguel Reichert, Douglas Rodrigo Kaiser

01/Aug/2008

Soil tillage promotes changes in soil structure. The magnitude of the changes varies with the nature of the soil, tillage system and soil water content and decreases over time after tillage. The objective of this study was to evaluate short-term (one year period) and long-term (nine year period) effects of soil tillage and nutrient sources on some physical properties of a very clayey Hapludox. Five tillage systems were evaluated: no-till (NT), chisel plow + one secondary disking (CP), primary + […]

Nutrient sources associated with soil tillage systems: technical aspects

Carla Maria Pandolfo, Carlos Alberto Ceretta, Milton da Veiga, Angelo Mendes Massignam

01/Apr/2008

Manure has been used as organic nutrient sources in different soil, climate, crop, and soil management systems. The effects of the continuous use of these systems is best evaluated by integrated analysis, based on different soil and crop attributes. This study was carried out to compare nutrient sources, mainly the organic ones, based on some chemical and physical soil attributes as well as crop attributes. The study was carried out at an experimental station of Epagri in Campos Novos, on […]

Mulch and soil organic carbon content and their relationship with the maximum soil density obtained in the proctor test

João Alfredo Braida, José Miguel Reichert, Milton da Veiga, Dalvan José Reinert

01/Aug/2006

The susceptibility of soils to compaction, measured by the Proctor test, decreases with increasing soil organic matter (SOM) content. For a given energy level, with increasing SOM contents the maximum obtained density decreases and the corresponding critical moisture content increases. Due to its low density, elasticity and deformation susceptibility, straw is potentially able to dissipate applied loads. This study was conducted to evaluate the SOM effect on the soil compaction curve and to evaluate the ability that mulch has to […]
