Abstract The objective of this work was to assess soil quality indicators obtained with different datasets to compare soil management systems in the Brazilian Cerrado. Three criteria were used to select soil physical, chemical, and biological indicators: the full set of indicators obtained, with 36 parameters, for which all the physical, chemical, and biological soil properties were determined; a subset of indicators selected by principal component analysis (20 parameters); and a subset of indicators with some frequency of use in the literature (16 parameters). These indicators were obtained from the following management systems: no-tillage, conventional tillage, and native cerrado vegetation. Soil samples were collected at 0.0-0.1-m soil depth, and soil... |

Abstract The importance of physicals properties of soil has an appreciable influence on their functions, water quality, climate control, nutrient cycling, and biodiversity, among others. These provide more ecosystem functions than just the nutritional contribution to agricultural production. Currently, the soil is under management pressure to the food production energy and raw material, which has led to its physical deterioration and degradation. The objective of this study is to evaluate the effects of bulk density and soil aggregate size silvopastoral systems (from tropical dry forest pastures) on the growth of guinea grass (Megathyrsus maximus) cv. Mombasa. To this end, two separate experiments were carried out under greenhouse conditions, by... |
