The influence of two organic amendments on norflurazon sorption-desorption processes in four soils with very different physicochemical characteristics was studied in laboratory experiments to evaluate the potential leaching of this pesticide through organic fertilized soils. Sorption-desorption experiments were performed on original soils and on a mixture of these soils with urban waste compost...

Soil organic carbon (SOC) plays an important role in the global C cycle, as well maintenance and improvement of soil quality. Over time, special attention has been paid to it study SOC reserves worldwide; however, reduced given assessing spatial patterns stock (SOCS) semi-desert ecosystems. In this line, there are no conclusive studies drylands Africa affected by aeolian processes (semi-desert ...

The economic importance of Bactrocera oleae (Rossi) and the problems associated with insecticides make necessary new management approaches, including deeper biological knowledge its relationship landscape structure. Landscape complexity reduces B. abundance in late summer–autumn areas high dominance olive groves, but effect structure spring less dominated by groves has not been studied. It is a...

Ten years after the event and the question as to exactly why a driver passed a signal at danger to cause the Ladbroke Grove rail disaster is still an open one. This paper uses the literature on human error and cognition, combined with critical path analysis, to provide further insight. Five aspects of train operation are drawn out of the known facts surrounding the incident: custom and practice...

Soil organic carbon (SOC) plays a fundamental role in soil health, and its storage is an important element to mitigate climate change. How include this factor Life Cycle Assessment studies has been the object of several papers still under discussion. SOC proposed as additional environmental information some applications Product Environmental Footprint (PEF). In framework wider activity aimed at...

The olive oil composition of eleven cultivars (cvs. Arbequina, Arbosana, Arroniz, Cornicabra, Frantoio, Hojiblanca, Manzanilla, Picual, Picudo, Redondilla and Royuela) cultivated in a high-density grove located non-traditional producing region (Valladolid, Spain) was studied during four consecutive crop seasons. results showed that the 122 monovarietal oils could be classified as extra virgin o...

The short- and medium—long-term effects of management hillside position on soil organic carbon (SOC) changes were studied in a centenary Mediterranean rainfed olive grove. One way to measure these is analyze the quality, as it assesses degradation degree attempts identify practices for sustainable use. In this context, SOC stratification index (SR-COS) one best indicators quality assess from co...

In recent years, North-western Spain has experienced an increase in the cultivated area of olive trees. The main propitious areas for groves are Miño and Sil basins, as a consequence their Oceanic climate with Mediterranean influence. objective this study is to determine characteristics reproductive biology, phenological aerobiological behaviour trees most northerly new plantation Iberian Penin...
