Soil organic carbon (SOC) is a major attribute of soil quality that responds to land management activities which is also important in the regulation of global carbon (C) cycling. This study evaluated bulk soil C and nitrogen (N) contents and C and N dynamics in three soil organic matter (SOM) fractions separated by density. The study was based on three tillage systems on farmer managed experiments (conventional tillage (CT), ripping (RP), direct seeding (DS)) and adjacent natural forest (NF) in Haplic Arenosols (sandy) and Rhodic Ferralsols (clayey) of Zimbabwe.
Performance of forest tree Khaya senegalensis (Desr.) A. Juss. under sewage effluent irrigation
The increasing demand of water in agriculture has compelled to search alternative source of water which could prove more economic and effective. Therefore, this investigation was carried out to study the effect of sewage effluents on Khaya senegalensis seedlings as well as on soil properties after 6, 12 and 18 months of plantation. The primary effluent treatment was highly significant (P
Land exploitation resulting in soil salinization in a desert–oasis ecotone
Understanding the process of agricultural land expansion and its impact on soil properties is crucial for land management and environmental health. A desert–oasis ecotone is typically located between an oasis at the lower reach of inland rivers and neighboring desert in arid regions, and acts as an interactive zone between irrigated farmland and the natural desert ecosystem. The arid region of northwest China has experienced dramatic land exploitation since the 1960s and soil salinization has been a serious environmental problem ever since.
Seroprevalence and risk factors associated with zoonotic parasitic infections in small ruminants in the Greek temperate environment
A cross-sectional serological study was carried out to screen the sheep and goat population of Thessaly, Greece for evidence of infection with Toxoplasma, Toxocara, Leishmania, and Echinococcus and to determine the risk factors related to herd characteristics, herd management practices, farmer status, and the bioclimatic variables associated with these zoonotic parasitic infections. A total of 540 sheep and goat serum samples were examined. The seroprevalence of infection in all examined animals was 24.5% for Toxoplasma, 32% for Toxocara, 0% for Leishmania and 85.9% for Echinococcus.
Measuring impacts of community forestry program through repeat photography and satellite remote sensing in the Dolakha district of Nepal
During the 1990's community-based forest management gained momentum in Nepal. This study systematically evaluates the impacts that this had on land cover change and other associated aspects during the period 1990–2010 using repeat photography and satellite imagery in combination with interviews with community members.
