Seeking to provide essential information about sustainable tillage systems, this work aimed to assess the effects of liming and soil cultivation systems on the soil hydrophysical attributes of a long-term cultivated sugarcane field in the tropical region of southeast Brazil. Infiltration tests and soil sampling down to 0.10 m were performed in order to determine saturated soil hydraulic conductivity, soil bulk density, soil total porosity, macroporosity, microporosity, and soil resistance to penetration. The studied areas include no-tillage (NT) and conventional tillage (CT) systems with 0 (CT0 and NT0) and 4 (CT4 and NT4) Mg ha⁻¹ of lime, and an adjoining area with native forest (NF). The data analysis included an analysis of variance followed by the Tukey test to compare different systems, assessment of the Pearson correlation coefficient between variables, and a principal component analysis of the dataset. The lowest bulk density and highest soil total porosity, macroporosity and saturated hydraulic conductivity were found in the NF. The bulk density in CT4 and NT0 was higher than in other systems, indicating the need for amelioration. NT4 is suggested as the most viable system for conservation agriculture in sugarcane fields, combining the benefits of no-tillage and liming to enhance soil hydrophysical functions.

Integrated crop-livestock-forest systems promote soil health and deliver more ecosystem services (ES) compared to conventional livestock systems, although most studies on the subject poorly describe the soil component of these systems. This preliminary studyassessed the condition of the soil resource and its role in the provision of ecosystem services from a Brazilian Oxidic soil under conventional and integrated livestock-based systems. Five systems were studied from pasture only to partial and fully integrated croplivestock-forest systems. All are located on one of the Brazilian Agricultural Research Corporation (Embrapa) Research Farms. Data for the quantification of the soil resource and ES for each of these livestockbased systems were retrieved from previous studiesand used to quantify soil health, the provision of food and fibre and climate regulation, as well as report their impacts on receiving environment. Soil organic carbon content, a key component of soil health, was higher in the most integrated system. Soil-based grass yields were lower in integrated systems due to competition for resources from the trees or space taken by crops but had the highest overall provision of food and fibre. Carbon sequestration by trees in the integrated systems offsets enteric methane emissions from beef production, and this ES contributes to mitigating climate change. Future studies should include analysis of all the naturalresources and a wider range of soil-based ecosystem services, along with impacts on receiving environmentsto provide a more complete picture of the performance of integrated livestock-based systems.
