“…In this case, the TM did not change the degree of compaction, possibly for the distribution of weight on the surface on all four wheels, which causes the pressure in the superficial layers are lower, this is consistent with reports of Botta et al (2006). Without the layer of 15-30 cm deep and continuous vehicular traffic of tractors, both features makes for changes in the sub-surface of soil travelled and in this case the 4 x 4 tractor showed a higher degree of compaction that the TL though not very different in magnitude, since in these conditions plays an important role densification of the soil, plowing floor and other physical factors of soil, coinciding with that described by Gameda et al (1987).…”

“…La compactación superficial está referida a la capa arable u horizonte A, donde se realizan en cada ciclo de cultivo los distintos aflojamientos y preparación de la cama de siembra y a la que se adicionan otras operaciones de cultivo. Este tipo de compactación ocurre con el empleo de conjuntos máquina-tractor de bajo peso y presión sobre suelos en condiciones de alta humedad o sobre suelos con mayor susceptibilidad a la compactación (Botta et al, 1997(Botta et al, , 2006Håkansson y Reeder, 1994). En contraste, la compactación subsuperficial es la que se transmite hasta el subsuelo, a profundidades de 40 cm o más, pudiéndose incrementar, entre otros factores no deseables y que pudieran llegar a ser permanentes: por on the order of 200 kN; These trends are presented in terms of seeking cheaper agricultural contractors in performance to reduce operating costs and enable increased acreage (Oskoui and Voorhees, 1985;Jorajuria et al, 1997).…”

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.

Abstract. South American countries with the highest surface of land under no-tillage (NT) management are Brazil, Argentina and Chile. In Argentina, 78.5 % of the agricultural land is cropped under NT management. Several experiments have confirmed the improvements in soil aggregation and infiltration achieved by NT management in dry-land farming areas associated with increases of bulk density (δ b ) under NT management. An increase in bulk density implies a reduction of the macro and mesoporosity that is in contradiction with the increased infiltration that occurs at macro and mesopores. We hypothesize that the increase of bulk density in NT management mainly affects the mesopores. We evaluated the evolution of the soil physical parameters in three management systems in four farmers' fields. We found that the reduction in total porosity under NT management is mainly a product of a reduction in the percentage of mesopores in the soil. In this work, the results indicate a modification of some soil physical parameters (porosity, near-saturated hydraulic conductivity, soil structure) due to uninterrupted agricultural production, but the management system did not affect the yields of crop.
