Runoff initiation, soil detachment and connectivity are enhanced as a consequence of vineyards plantations.
2017
[EN] Rainfall-induced soil erosion is a major threat, especially in agricultural soils. In the Mediterranean belt, vineyards are affected by high soil loss rates, leading to land degradation. Plantation of new vines is carried out after deep ploughing, use of heavy machinery, wheel traffic, and trampling. Those works result in soil physical properties changes and contribute to enhanced runoff rates and increased soil erosion rates. The objective of this paper is to assess the impact of the plantation of vineyards on soil hydrological and erosional response under low frequency - high magnitude rainfall events, the ones that under the Mediterranean climatic conditions trigger extreme soil ero…
An economic, perception and biophysical approach to the use of oat straw as mulch in Mediterranean rainfed agriculture land
2017
[EN] Soil erosion is a key cause of land degradation in agriculture lands; and it is a worldwide threat that must be solved by means of nature-based strategies to be able to achieve sustainability. The use of mulches can be a solution, but there is a lack of information on long-term effects of the use of straw. Furthermore, little is known about the perception of farmers and the economic cost on the implantation of straw as a conservation measure. Eight paired plots were selected in Sierra de Enguera on an agriculture field to determine the effect of straw cover on soil erosion. Four plots were tilled three times per year (Control) and four plots were not ploughed and 0.125 kg m(-2) y(-1) o…
The impact of agricultural management on selected soil properties in citrus orchards in Eastern Spain: A comparison between conventional and organic …
2017
The agricultural management of citrus orchards is changing from flood irrigated managed orchards to drip irrigated organic managed orchards. Eastern Spain is the oldest and largest European producer of citrus, and is representative of the environmental changes triggered by innovations in orchard management. In order to determine the impact of land management on different soil quality parameters, twelve citrus orchards sites were selectedwith different land and irrigation management techniques. Soil samples were taken at two depths, 0-2 cmand 5-10 cm for studying soil quality parameters under the different treatments. Half of the studied orchardswere organicallymanaged and the other sixwere …
Oscuro sobre claro. Consideraciones en torno al hidrónimo Luxia
2013
The hydronym Luxia, one of which uses Pliny to refer to rivers near to Huelva, has been considered traditionally derived from an Indo-European root close to the meaning of "clear" or "bright". The dark waters of the Odiel and Tinto advise to find another etymological solution for the hydronym. These dark rivers printed a peculiar religious bias to the territories that cross, explaining the emergence of sanctuaries linked to underground deities.
