“…Our results also confirm the findings of Materechera et al (1992), who showed that the average root diameter of the cotton plants increased as the root growth in the compacted soil layer was reduced. Glinski and Lipiec (1990) observed an increase in the average root diameter in compacted soil for barley, peas, and maize, and this effect is due to the high extension of the cortex, in which the cells were short in the longitudinal direction and large in the transversal direction, whereas the cell volume remained unchanged.…”

“…These similar responses represented by a single shape of the curves for the three systems in each cycle show a homogeneity in the behaviour of penetration resistance independent of treatment implements. The increase in resistance values with increasing depth is usually attributed to the presence of a vertical discontinuity between the horizon and subsoil tillage without work (Glinski and Lipiec, 1990).…”

ResumenEl comportamiento a corto plazo de las propiedades físicas de un vertisol, bajo sistemas de labranza tradicional y de conservación, en la zona de producción de maíz (Zea mays L.) del Valle Toluca-Atlacomulco, aún no ha sido reportado. La presente investigación se desarrolló durante un periodo de tres años (2010 -2012) en Toluca, Estado de México, para evaluar el efecto de los sistemas de labranza tradicional (LT), mínima (LM) y cero (LC), sobre la compactación de un vertisol y el rendimiento del maíz. Para determinar la compactación del suelo, se midieron las variables de densidad aparente (Da), resistencia a la penetración, mediante el índice de cono (IC), y velocidad media de infiltración del agua (VMI), en cada ciclo de cultivo. En general, para todos los ciclos y sistemas, la Da se incrementó con la profundidad y el mayor valor se presentó en la capa más profunda. El valor más alto de Da (1.64 g cm -3 ) se observó en LC a 15-30 cm de profundidad. Para el IC, el valor más alto (3 998 kPa), así como el mayor valor promedio (3 401 kPa), también fueron observados en LC. Para todos los ciclos de cultivo, la mayor VMI promedio se registró en LT (0.088 mL cm -2 min -1 ). Los mayores valores de rendimiento, en todos los ciclos agrícolas, fueron obtenidos en LM. El análisis de las AbstractThe short-term behaviour of the physical traits of a vertisol under traditional systems and conservation tillage in the production area of maize (Zea mays L.) Valley TolucaAtlacomulco, has not been reported so far. This research was developed over a three year period (2010 -2012) in Toluca, State of Mexico, to evaluate the effect of conventional tillage systems (LT), minimum (LM) and zero (LC) on the compaction of a vertisol and yield of maize. In order to determine soil compaction, we measured the variables of bulk density (Da), resistance to penetration by the cone index (CI), and mean velocity of water infiltration (AIR) in each crop cycle. In general, for all cycles and systems, Da increased with depth and showed the highest value in the deepest layer. The highest value of Da (1.64 g cm -3) was observed in LC at 15-30 cm depth. For the CI, the highest value (3 998 kPa) and the highest average value (3 401 kPa), were also observed in LC. For all crop cycles, the highest mean AIR was recorded in LT (0.088 mL cm -2 min -1 ). The highest yield values in all agricultural cycles were obtained in LM. The analysis of the different variables could not establish, in the short term, clear trends in the increase or remediation of compaction parameters of vertisol under different tillage systems. IntroducciónEn un contexto agronómico, la compactación es el resultado de la aplicación al suelo de cualquier fuerza, por ejemplo, la ejercida por la labranza y el tránsito rodado de maquinaria agrícola, que incrementa la densidad aparente del suelo y, por consiguiente, disminuye la porosidad del mismo (Soil Science Society of America, 2013). La compactación del suelo se asocia frecuentemente con una reducción en el rendimiento del cultivo...

“…According to Glinski and Lipiec (1990), under wet conditions, soils with high organic matter content could be more resistant to compaction than soils with low organic matter. Lapen et al (2002) describe positive associations between soil draft force measurements and soil water content.…”

This paper reviews the works related to the effect of soil compaction on cereal yield and focuses on research of field experiments. The reasons for compaction formation are usually a combination of several types of interactions. Therefore one of the most researched topics all over the world is the changes in the soil's physical and chemical properties to achieve sustainable cereal production conditions. Whether we are talking about soil bulk density, physical soil properties, water conductivity or electrical conductivity, or based on the results of measurements of on-line or point of soil sampling resistance testing, the fact is more and more information is at our disposal to find answers to the challenges.Thanks to precision plant production technologies (PA) these challenges can be overcome in a much more efficient way than earlier as instruments are available (geospatial technologies such as GIS, remote sensing, GPS with integrated sensors and steering systems; plant physiological models, such Decision Support System for Agrotechnology Transfer (DSSAT), which includes models for cereals etc.). The tests were carried out first of all on alteration clay and sand content in loam, sandy loam and silt loam soils. In the study we examined especially the change in natural soil compaction conditions and its effect on cereal yields.Both the literature and our own investigations have shown that the soil moisture content changes have the opposite effect in natural compaction in clay and sand content related to cereal yield. These skills would contribute to the spreading of environmental, sustainable fertilizing devoid of nitrate leaching planning and cereal yield prediction within the framework of the PA to eliminate seasonal effects.
