“…Although high C stocks in the soil were observed in TM, the total C stocks were reduced by 16% compared to ASP and by 65% compared to CAT. Other studies in TM areas confirmed this decreasing trend, particularly for the soil compartment (MAIA et al, 2007;VEUM et al, 2011;NOVARA et al, 2012).…”

-This study evaluated the contribution of agroforestry (AFS) and traditional systems to carbon sequestration and nutrient reserves in plants, litter and soil. The study was carried out in the semiarid region of Brazil in a long-term experiment on an experimental farm of the goat and sheep section of the Brazilian Agricultural Research Corporation (Embrapa). Two agroforestry systems were investigated: agrosilvopastoral (ASP) and forest-pasture areas (SP) as well as traditional agriculture management (TM), two areas left fallow after TM (six fallow years -F6 and nine fallow years -F9) and one area of preserved Caatinga vegetation (CAT). Soil, litter and plants were sampled from all areas and the contents of C, N, P, K, Ca and Mg per compartment determined. The AFS (ASP and SP) had higher nutrient stocks than the traditional and intermediate stocks compared to the preserved Caatinga. In the ASP, a relevant part of the nutrients extracted by crops is returned to the system by constant inputs of litter, weeding of herbaceous vegetation and cutting of the legume crops. After fallow periods of six and nine years, carbon and nutrient stocks in the compartments soil, litter and herbaceous plants were similar to those of the preserved Caatinga (CAT), but still lower than under natural conditions in the woody vegetation.Keywords: Agroecology; Family farming; Agroforestry.

“…The three watersheds are north facing with a 0-3 % slope; they have been planted in a corn-soybean rotation with notill management since 1991. Previous research at the site indicates no effect of landscape position on soil organic C, total N (Veum et al 2011) or water-stable aggregates (Veum et al 2012). Upland filter strips (4.5 m width) were established along the contour in 1997 and no-till cropping continues to occur in 23-36 m strips between the VFS.…”

“…This fact reinforced that the implementation of reduced tillage is a good measure to increase SOC in topsoils. Besides, this SOC increase will influence other factors, such as infiltration, water content, porosity and soil aggregation (Veum et al, 2011), improving soil quality (Govaerts et al, 2009). In addition, higher ACF in depositional topsoil samples than in eroded ones suggested that, in agreement with Carter (1992), the more bioreactive carbon fraction was more sensitive to soil management than was stable carbon.…”

Mediterranean mountain agroecosystems are sensitive areas to soil degradation due to climatic conditions and anthropogenic pressure from agriculture and grazing practices.Soil redistribution processes affect the spatial variability of soil properties and nutrients, as soil organic carbon and nitrogen (SOC and SON) Cs inventory than the reference for the area. In addition, there was a generalised loss of soil nutrients. SOC gain was found in less than 1% of the study field and there was a large loss of SON compared to the undisturbed reference site. Higher and significant (p≤0.01) contents of soil nutrients were found in topsoil than in bulk samples. Furthermore, there was an enrichment of the relative contribution of ACF to total SOC in sampling points where there was a 137 Cs gain in both bulk and topsoil samples as a consequence of the soil redistribution particles by tillage and runoff.Understanding patterns of soil nutrients can be useful for developing or implementing land management strategies to preserve soil quality in Mediterranean agricultural areas.
