ABSTRACT Coastal Tablelands are flattened areas cut by valleys, which have predominantly Argissolos Amarelos (Yellow Argisol) and Latossolos Amarelos (Yellow Latosol). In contrast to this landscape, there are depressed circular areas, known as ponds, that create new dynamics in soil formation, due to the intermittent presence of water throughout the year. The soils of these pond areas are little known, which leads to the possibility of inappropriate use and management. The objective of this study was to describe the soils […]

The estimation of non available soil variables through the knowledge of other related measured variables can be achieved through pedotransfer functions (PTF) mainly saving time and reducing cost. Great differences among soils, however, can yield non desirable results when applying this method. This study discusses the application of developed PTFs by several authors using a variety of soils of different characteristics, to evaluate soil water contents of two Brazilian lowland soils. Comparisons are made between PTF evaluated data and field […]

Face the planosols (Albaqualf) importance to the agricultural activities in the South Region of the State of Rio Grande do Sul, Brazil, the effect of chiselling on physical parameters of this soil was studied. Experiments were carried out at the Agricultural Machines Experimental Area of EMBRAPA – CPACT, in Capão do Leão, RS, November, 1994. It was analysed the effect of chiselling at three operating speeds (4.76; 3.63 and 2.58 km h-1), in two levels of soil moisture content (119.6 […]
