Determining temporal changes in field-saturated hydraulic conductivity ( K fs ) is important for understanding and modelling hydrological phenomena at the field scale. Little is known about the sensitivity of temporal change estimates to the method used for measuring K fs . The objective of this...
Growth and yield of pearl millet ( Pennisetum glaucum ) in the West African Sahel are characterized by significant spatial variability at short distances (5–20 m). Several studies have suggested that this variability is caused by aeolian redistribution of relatively fertile topsoil material....
Farm management practices have led to low soil organic carbon (SOC) and total nitrogen (TN) in Australia. Change in SOC and TN during 21 years of different rotation, tillage and stubble management systems were studied on a red earth, a Chromic Luvisol, at Wagga Wagga, NSW, Australia. The...
Bread wheat ( Triticum aestivum ) yields are often low on peasant farmers’ fields in Ethiopia due to the use of sub-optimal crop management practices. Four multi-factor crop management trials were initiated during 1992 in the south-eastern highlands of Ethiopia. Two of the trials were based on...
The objectives of this study were to determine the relationships between soil penetration resistance (PR) and some physical soil properties affecting soil PR, with classical statistical and geostatistical methods, and to observe the formation of a plow pan and its variability in the study area,...
The objective of this study was to determine in a long-term experiment (13 years) the effect of three different crop rotations (R1: wheat ( Triticum aestivum )–soybean ( Glycine max ), R2: wheat–soybean–vetch ( Vicia villosa )–maize ( Zea mays ), and R3: wheat–soybean–oat ( Avena...
