“…For most of the NT soil, the density value increased, while the macroporosity was reduced (Table 3, Figure 2), confirming Horn et al (1995), Jung et al (2010) and Peng et al (2012), who indicate that these are sensitive indicators of changes imposed on the soil by the management. On the other hand, the change in the soil use also led to changes in microporosity values, but of a lower magnitude than those observed for macroporosity.…”

“…This corroborates Munkholm and Schjonning (2004), who found that the aggregate structure is affected by the management of very moist soil. Alterations in these characteristics lead to changes in soil water, air and temperature flow dynamics, changes in water storage and redistribution Hatano, 2003), root system development (Bengough et al, 2006;Jung et al, 2010) with modifications in root syatem physiology and changes in nutrient uptake by plant roots.…”

“…This is because the compression can not be considered as a value of a single variable, but as the integration and understanding of a set of variables defining a degree of compression, tolerable or not, by the plant. Variables such as bulk density, pore distribution and arrangement, water content, permeability to air and/or water, soil resistance and structure (Horn et al, 1995;Jung et al, 2010;Peng et al, 2012), its development (Bengough et al, 2006;Jung et al, 2010), morphology and root physiology (Bengough et al, 2006;Lipiec et al, 2012), and the development and performance of the aerial part (Jung et al, 2010;Botta et al, 2010) are some of the indicators that help in understanding the degree of compaction.…”

The degree of soil compaction is intensified by its inadequate management, compaction being variable depending on soil type since even under identical management conditions, different types have different abilities to withstand load. The objective of this study was to evaluate the susceptibility to compaction of different classes of soils under no-tillage (NT) croping system compared to the original condition. Thus, i) soils with the same source material have distinct resistance to compression with increased NT adoption time; ii) the most sensitive indicators of this change are the ratios mass:volume and volume:volume and; iii) there is a relationship between resistance and compaction susceptibility with the amount and type of oxide. Soil samples were collected in areas under NT and under natural condition in order to assess the impact imposed by the NT on the attributes density and porosity, precompression stress and compressibility index and relate them to the oxide type of, and content in, the soils under study. The results show that the density and macroporosity were those most affected by the NT agricultural use, regardless of soil type, that is, its dynamic is related more to soil use and less to mineralogical characteristics. The soil resistance and compaction susceptibility were higher in soil developed in basalt, followed by those developed in sandstone and granite. Both the organic matter content and type and concentration of iron oxides were related to the soil resistance and susceptibility to compaction.

“…Thus, appropriate management practices are required. JUNG et al (2010) suggested a combination of management practices for mitigating or delaying soil compaction. Such practices include controlled farm machinery traffic and the use of crop rotations that include plants with deep roots that are strong, able to penetrate relatively compacted soils and provide good coverage and soil organic matter to improve the physical soil properties and the chemical and biological soil conditions and help control invasive plants.…”

This study aimed to evaluate the spatial dependence of physical attributes in a soil cultivated with Brachiaria grass. A 12-m regular sampling grid was established within an area of 3.500 m 2 . Thirty-five soil samples were collected at 0-30 cm depth for particle density, bulk density, texture and total porosity analysis. These data were evaluated using statistical methods of indicator kriging and the GS+ software. The GS+ software was used to develop three-dimensional maps and evaluate semivariograms. The spatial dependence was e valuated using experimental semivariograms. The analyzed attributes indicated the occurrence of spatial dependence when fit to the exponential model. Areas with higher porosity occurred in the regions with lower bulk densities and higher particle densities.KEYWORDS: spatial variability, management system, kriging. ATRIBUTOS FÍSICOS DE UM SOLO COM COBERTURA DE PASTAGEM ANALISADOS POR MEIO DA GEOESTATÍSTICA NA REGIÃO SUDESTE DE GOIÁSRESUMO: O objetivo deste estudo foi avaliar a dependência espacial de a lguns atributos físicos de um solo cultivado com Brachiaria, antes da implementação de adubo verde como transição agroecológica para o cultivo de cana-de-açúcar orgânica. Atribuiu-se uma grade de coordenadas para que as amostras pudessem ser georreferenciadas obtendo os valores de variabilidade espacial da densidade das partículas, densidade do solo, teor de areia, argila e da porosidade total em uma área de 3.500 m 2 . As amostras do solo foram coletadas em uma malha regular de 12 x 12 m, totalizando 35 pontos, na profundidade de 0-30 cm. Os dados foram avaliados por meio da geoestatística, apoiado no software GS+ que possibilita, além do estudo do semivariograma, a elaboração de mapas tridimensionais. A dependência espacial foi avaliada por meio de semivariogramas experimentais. Os atributos analisados apresentaram dependência espacial, ajustando-se ambos ao modelo exponencial. As áreas de maior porosidade ocorreram em regiões com menor densidade do solo e maior densidade de partículas. PALAVRAS-CHAVE:variabilidade espacial, sistema de gestão, krigagem.

“…Como consecuencia de una mayor intensidad de tránsito rodado con esas cargas sobre los ejes, se intensifica la compactación en suelos de cultivo y, por lo tanto, el poco crecimiento del sistema radical de las plantas, además de bajos rendimientos y calidad del agroecosistema (Jung et al, 2010). Adebiyi et al (1991), plantean que la compactación puede definirse como la compresión de una masa de suelo hasta lograr un volumen menor, originando, en consecuencia, un incremento en la densidad como resultado de las presiones externas aplicadas.…”

ResumenLa compactación del suelo es una de las áreas más importantes de la investigación para la protección del ambiente a nivel mundial. Los problemas de compactación del suelo se presentan con mucha frecuencia en áreas donde se tiene una mecanización agrícola extensiva e intensiva. Al respecto, esta investigación tiene como objetivo determinar el grado de compactación producido por el tránsito de tractores con diferentes sistemas de rodaje, masas e inflado de sus neumáticos, en un Vertisol. Para tal efecto se probaron tres tipos de tránsito rodado (3, 5 y 10 pasadas de tractores con diferentes masas). La presión media específica de uno de los tractores originó un aumento en el grado de compactación del suelo pero, a partir de las 5 pasadas de tránsito, el impacto fue mínimo. El tractor con fórmula 4 x 4 en su sistema de rodaje, fue el que menos alteró el grado de compactación en la capa superficial del suelo. Existe una relación lineal entre la presión media específica de los tractores y el aumento del grado de compactación del suelo en la mayoría de las variantes ensayadas.Palabras clave: humedad del suelo, índice de cono, multiarado. AbstractSoil compaction is one of the most important areas of research for environmental protection worldwide. The soil compaction problems occur frequently in areas where we have an extensive and intensive agricultural mechanization. In this regard, this study aims to determine the degree of compaction caused by tractor traffic with different systems of shooting, weight and inflating the tires in a Vertisol. For this purpose three types of road traffic were tested (3, 5 and 10 strokes of tractors with different weights). The specific average pressure of one of the tractors led to an increase in the degree of compaction but, beginning at 5 passes traffic, the impact was minimal. The tractor formula 4 x 4 running on the system least altered the degree of compaction in the topsoil. A linear relationship between the average specific pressure tractors and increasing the degree of compaction in most of the variants tested.
