Management of forage grazing height by cattle may compromise soil physical properties. The objective of this study was to evaluate the influence of grazing height of brachiaria (Urochloa ruziziensis) and the average stocking rate, after three years into an integrated soybean crop-livestock system, in the physical attributes of a Haplorthox (Rhodic Ferralsol). A randomized complete block experimental design with three replications was used. Five treatments were evaluated in 1 ha experimental plots: grazing heights of 10, 20, 30, and 40 […]

The least limiting water range (LLWR) is one of the best indicators of soil physical quality in intensive production systems. The objective of this study was to evaluate the physical quality of a Typic Haplorthox by the LLWR after three crop growing seasons and the first year of crop-livestock integration in Xambrê, northwestern Paraná, Brazil. The experiment was established in a randomized block design with three replications. Treatments consisted of four brachiaria heights before grazing (0.10; 0.20; 0.30, and 0.40 […]

It has been found that the results of the land use and management techniques adopted for soils derived from Caiuá sandstone in the Northwest of Paraná are not always satisfactory in terms of crop yields. In this region, sandstone occurs in two forms: the Caiuá and Paranavaí Formations, with differences in soil particle size. We hypothesized that the water retention and availability for agricultural production is lower in the Caiuá soils, due to the higher proportion of coarse sand than […]
