Effects of lime and phosphorous application on chemical properties of soil, dry matter yield, and phosphorus concentration of barley (Hordeum vulgare) grown on Nitosols of Emdibir, Southern Ethiopia

The effects of lime and P fertilizer application on chemical properties of acid soil, and dry matter yield (DMY) and phosphorus concentration of barley were investigated in a greenhouse experiment in 2013. The experimental soil was collected from Emdibir, South-Western Ethiopia. Five lime levels (CaCO3) (0, 6093, 12186, 18280, and 24373 mg CaCO3 kg-1 soil) in a factorial combination with five phosphorus (TSP) rates (0,...

Organic carbon sequestration in mineral soil layers of cold-temperate mixed forests

The aim of this study is to analyze the concentration of soil organic carbon (SOC) and C stocks in cold-temperate mixed forests in southern Québec, Canada. More specifically, the analysis deals with SOC concentrations and C stocks with respect to other key soil properties and environmental factors (such as soil pH, nitrogen, texture, structure, bulk density, litter thickness, drainage), including vegetation data...

Effect of rhizobial inoculation combined with phosphorus fertilizer on nitrogen accumulation, growth and yield of soybean in Benin

The objective of this study was to determine the amount of phosphorus application needed for the Bradyrhizobium inoculation to improve soybean N uptake and grain yield. Two factors were investigated: inoculation with Bradyrhizobium diazoefficiens strain USDA 110 and application of phosphorus fertilizer with different doses (0; 50; 100 and 150 kg ha-1 P2O5). Trials were carried out in two agro-ecological zones (ZAE) in...

Modifications induced in soil physicochemical properties by repeated fire for different fuel load treatment in a West African savanna-woodland

Fire is known to stimulate growth of savanna vegetation, promote species’ diversity, and regulate tree and grass balance. However, the timing and frequency at which savannas are burned and the fuel properties can affect residual soil nutrient content and, ultimately, productivity. The objective of this study is to characterize changes in soil physical and chemical properties in a savanna-woodland subject to...
