Estudios sobre el contenido de amonio en un Vertisol de secano mediterráneo. Influencia del sistema de laboreo y profundidad de suelo
(Agronegocios, 2015)La mineralización es un concepto que no siempre se interpreta del mismo modo. A veces se considera como la conversión de N orgánico a formas inorgánicas (amonio, amoniaco y nitratos) y otras se considera como un sinónimo ... -
Monitoring wheat root development in a rainfed vertisol: tillage effect
(Science Direct, 2010)Good root system development is essential for optimum wheat (Triticum aestivum L.) grain yield, especially under water-limiting conditions. Published information about the influence of tillage system on root dynamic and ... -
Effect of tillage system on the root growth of spring wheat
(SpringerLink, 2009)Little research has examined the influence of tillage system on root growth in wheat grown on rainfed Vertisols. A 3-year field study (2003, 2004 and 2005) was carried out on a typical Vertisol (southern Spain), to determine ... -
Chickpea and faba bean nitrogen fixation in a Mediterranean rainfed Vertisol: effect of the tillage system
(Science Direct, 2011)Efficient management of legumes in order to maximize benefits depends on a correct field assessment of N2 fixation. A field experiment was conducted during a 6-year period (2001–2002 to 2006–2007) in Córdoba (Southern ... -
Stratification ratios in a rainfed Mediterranean Vertisol in wheat under different tillage, rotation and N fertilisation rates
(Science Direct, 2012)Semiarid Mediterranean climatic conditions and intensive tillage systems accelerate soil organic matter losses. Therefore, assessing agricultural practices that enhance storage of soil organic matter is needed. Stratification ...
