This paper aimed to evaluate the influence of management practices of marandu grass, at eucalyptus shading levels in a forest grazing system, on organic carbon (OC) and nitrogen (N) stocks, and on soil chemical characteristics in the Brazilian Cerrado. The experimental design adopted was entirely random with five repetitions. In the plots were allocated the environments with different light availability, and a treatment with marandu grass in full sun. The management of marandu grass pasture was distributed in the subplots with pre-pasture at 30, 40, 50, and 60 cm high. Evaluations were repeated in two crop cycles in year 1 and year 2. Soil chemical characteristics, OC and N stocks were analyzed. The management of marandu grass at 50 cm height in the forest grazing system provided higher levels of OC, N, organic matter in the soil and an increase in fertility, compared to monoculture pasture, with repercussions in two years. The integration of eucalyptus and marandu grass pasture contributes with greater stocks of OC and N in the soil strips closest to the tree row, due to greater nutrient cycling. Marandu grass in forest grazing systems with shading varying from 40 to 60% present greater efficiency and maintenance of soil chemical attributes, demonstrating greater sustainability compared to monoculture pastures.

“…Studies have shown that the integration of production with pastures, with the adoption of forest grazing systems, can increase soil OC stocks and improve land use sustainability (Almeida et al, 2021;Frazão et al, 2021;Jose and Dollinger, 2019;Ribeiro et al, 2019;Schinato et al, 2023), increase the quality and productivity of agricultural products, and the conservation of environmental resources (Hanisch et al, 2022;Santos et al, 2019).…”

“…Studies about the detailed arrangement of dryland plant species in the agroforestry system still have a limited purpose, to increase slope stability only, but do not pay attention to its economic and social functions [21][22][23]. Besides, plant layout arrangements that have also been widely discussed aim to protect the soil from nutrient loss due to erosion [24][25][26].…”

Agroforestry, as the dominant land use at the volcanic foot slope in Java Island, is prone to landslide due to a combination of rough relief and thick soil layer. However, evaluations of specific vegetation patterns against landslide reactivation due to soil erosion, which relays on the existing slope units and geomorphological processes, are still limited. The research data were collected through aerial photo interpretation by delineating morphological units of old landslides, slope units, and the existing land use. This was followed by field surveys for two consecutive purposes, i.e., (1) verification of aerial photo interpretation and (2) identification and intensity assessment of existing geomorphological processes. The data were tabulated according to slope units, as a basis for tree and crop arrangement in controlling erosion and landslide, by considering economic, social, and ecological functions. The agroforestry would control the landslides reactivation if the tree and crop arrangement was based on the morphological units formed by the previous landslide. The slope units are classified into residual zones at the highest elevations with flat slopes, erosion zones with the steepest slope, and sedimentation zones at the lowest elevations with gentle slopes. Trees and crops at those three units of the former landslide have different functions in controlling processes of rill erosion, gully erosion, and soil creep.
