The conversion of natural forests into conventional agricultural and cattle systems is very harmful to environmental sustainability. In Brazil, mainly at Atlantic Rain Forest, that deforestation can be observed by a great number of small widespread unconnected fragments, where genetic erosion is a result of reduced above- and belowground biodiversity, increased organic matter decomposition and thus, decreasing soil C storage. Agroforestry systems provide food production, but little is known about how standing litter can affect the nutrient supply for ecological-based agroforestry systems. This work was conducted in family small farms containing conventional agriculture, pasture, ecological-based agroforestry (summarized here as ecological agroforestry) and natural regeneration, where standing litter was collected, separated into different fractions, weighted and analysed for nutrient contents. Standing litter was greater in natural regeneration (13.7Mgha-1) and ecological agroforestry (10.2Mgha-1), than in pasture (4.8Mgha-1) and conventional agriculture (3.6Mgha-1), all mainly composed by leaves and branches. Standing litter of conventional agriculture was richer in N, P and Mg, due to external inputs. Standing litter of ecological agroforestry was richer in Ca, while pastures, in K. Standing litter from natural regeneration returned greater amounts of N (171.4Mgha-1), P (37.7Mgha-1), Ca (199.0Mgha-1) and Mg (44.3Mgha-1), while ecological agroforestry had greater amounts of K (346.9Mgha-1). Ecological agroforestry results were similar to natural areas, and significantly higher than monocultures, indicating the importance of litter management for sustainability of diverse land-use systems.
