Nitrate accumulation in the soil profile: long-term effects of tillage, rotation and N rate in a Mediterranean Vertisol
(Science Direct, 2013)
Excessive application of fertiliser in agriculture can have detrimental effects, one of which is diffuse contamination with nitrates. An 18-year field study was conducted on a typical rainfed Mediterranean Vertisol to ...
Nitrogen rhizodeposition by wheat under different tillage systems in a rainfed Vertisol
(Science Direct, 2013)
Roots and the nutrients that they deposit into the soil are a natural source of N for a current crop, or a subsequent crop in the case of rotations. Despite the importance of this process, there are few field studies of ...
Chickpea water use efficiency as affected by tillage in rainfed Mediterranean conditions
(Science Direct, 2013)
Under rainfed Mediterranean conditions, chickpea production can be increased by improving the soil water content (SWC). This study was conducted on a Vertisol in southern Spain over a period of ten years (2000-2009) to ...
