In sub-Saharan Africa, including Uganda, there is declining soil fertility and limited on-farm use of inorganic fertilizers due to poverty and limited subsidies for inorganic fertilizer use. Thus, integration of soil fertility improving tree species (SFITs) in farming systems remains a plausible option to sustaining soil productivity. However, knowledge of the effects of many of the locally growing farmer perceived soil fertility enhancing tree species on to soil chemical and nutrient contents are thus still lacking, and this has constrained decisions on their adoption and scaling up. The objectives of this paper were to identify farmers' preferred soil fertility improving tree species in agropastoral communities of Kyeizooba subcounty Bushenyi district, and characterize their litter content and assess their effect on selected soil chemical properties. Semistructured questionnaires were administered to 333 randomly selected agropastoral farmers. Litter and soils under canopy soils were sampled from three different environments: Under canopy radius (A), canopy edge (B), open pasture land up to thrice the canopy radius (C). Results revealedEucalyptusas the most common tree species on livestock farms, followed byErythrina abyssinica. The highest litter content was recorded forMarkhamia lutea(240 g/cm2under its canopy) followed byCroton macrostachyus(90 g/cm2), and 19 g/cm2Erythrina abyssinica. Nitrogen was higher (P=.02) inErythrina abyssinicalitter, K and carbon inCroton macrostachyuslitter (P=.03). These results give evidence that of soil improversErythrina abyssinica,Croton macrostachyus, andMarkhamia luteamay positively affect soil fertility. Farmers' indigenous knowledge and or valuation of important tree species can be relied on, and thus, their indigenous knowledge need to be incorporated during identification of tree species for promotion in farming systems.

Abstract Background There is scarcity of scientific information on stocks and retention rate of soil organic carbon (SOC) among mixed farming systems in humid Western Ethiopia. The objectives of study were to determine the SOC stocks and retention rates along a 53-km long toposequence of Didessa watershed. The study was conducted in mixed farming systems (annual arable cropping, grazing, fallow, grassland, coffee agroforestry, Eucalyptus agroforestry and mechanized irrigated sugarcane production) within an elevation range of 1273 to 2543 meter above sea level. Results The results revealed that land use types greatly affected SOC stocks and retention rates in the upper 20 cm soil depth. The SOC stocks ranged from 9.27 to 13.5 Mg C ha− 1 (0-20cm) while the retention rates were 0.11, 0.2, 0.28, 0.31 and 1.14 Mg C ha− 1 yr− 1 for coffee agroforestry, fallow, grazing, Eucalyptus agroforestry and irrigated sugarcane production systems, respectively. Conclusion The retention rates demonstrated that the different farming systems are potential source of C sinks. The study indicated that the farming systems are efficient in sequestering SOC and their benefits can be further adopted for their economic values, social significance, restoration of degraded land and sequestration of C in humid tropical Western Ethiopia.
