A carbon-sink in a sacred forest: Biologically-driven calcite formation in highly weathered soils in Northern Togo (West Africa)
(Elsevier, 2020-11-10)Soil organic matter (OM) is a source of fertility for food provisioning and a means for climate mitigation. A high pedodiversity observed over very short distances due to both past and present land use, such as in Western ... -
A comparison of new and existing equations for estimating sensible heat flux using surface renewal and similarity concepts
(American Geophysical UnionWiley, 2006)This paper describes two approaches for estimating sensible heat flux, using surface renewal and similarity concepts. One approach depends on a temperature structure function parameter and is valid in the inertial sublayer. ... -
A dynamic model based on the piston flow concept for the thermal characterization of solar collectors
(Elsevier, 2012)A simple, transient model for the characterization of the dynamic thermal performance of solar thermal collectors was developed and experimentally validated. The proposed model equation is linear with respect to the input ... -
A manera d'Introducció : nitrats, aigua i agricultura, un problema modern d'ús del sòl
(Institució Catalana d’Estudis Agraris, 1999) -
A method based on high‐frequency temperature measurements to estimate the sensible heat flux avoiding the height dependence
(American Geophysical UnionWiley, 2002)A new method to estimate the sensible heat flux H using high‐frequency temperature data has been proposed. The new method proposes to scale the mean eddy vertical velocity responsible for the air parcels renewal using ... -
A method for livestock waste management planning in NE Spain
(Elsevier, 2003)A method of decision-making on livestock wastes management in areas with nutrient surplus due to high livestock density is applied in Catalonia (NE Spain). Nutrient balance is made considering soil nitrogen application ... -
A proposal of nitrogen balance in a very high density olive orchard
(El Oued University, 2016)The nitrogen (N) balance was estimated in a very high density olive orchard in north- east of Spain, in order to calculate the inputs and outputs of N related to tree response and soil nitrogen availability. The calculate ... -
A Short-term Study to Compare Field Strategies for Ammonia Emission Mitigation
(Crop Science Society of America, 2018-10-16)Abatement of ammonia (NH3) emissions is crucial in calcareous soils under semiarid Mediterranean climates. The aim of the study was to compare NH3 emissions using different slurry application methods. An experiment was ... -
A simple parameterization of bulk canopy resistance from climatic variables for estimating hourly evapotranspiration
(Wiley, 2006)This paper examines a model for estimating canopy resistance rc and reference evapotranspiration ETo on an hourly basis. The experimental data refer to grass at two sites in Spain with semiarid and windy conditions in a ... -
Accuracy assessment of digital terrain model dataset sources for hydrogeomorphological modelling in small Mediterranean catchments
(MDPI, 2018)Digital terrain models (DTMs) are a fundamental source of information in Earth sciences. DTM-based studies, however, can contain remarkable biases if limitations and inaccuracies in these models are disregarded. In this ... -
Acidification assessment after peat bog drainage in the Catalan Pyrenees (NE Iberia)
(MDPI, 2019-09-18)The Pyrenean range (NE Iberian Peninsula) has some favourable lithological and climatic conditions (iron-rich parent materials and udic moisture regimes) for the formation of acid sulfate soils (ASS) that have not been ... -
Acumulación de sedimentos finos en el lecho del río Isábena: efectos sobre el transporte y la dinámica sedimentaria
(Asociación Española para el Estudio del Cuaternario y la Sociedad Española de Geomorfología, 2011)El almacenamiento de sedimentos y sus efectos sobre el transporte de sedimentos y su dinámica ha sido estudiado en un tramo de ~3 km en el río Isábena durante un año hidrológico medio (2007-2008). La acumulación total ... -
Advances in the prognosis of soil sodicity under dryland irrigated conditions
(Elsevier, 2014)Salt-affected soils, both saline and sodic, may develop under both dryland and irrigated conditions, affecting the physical and chemical soil properties, with negative consequences in the environment, in crop production ... -
Aggregate Development and Organic Matter Storage in Mediterranean Mountain Soils
(Soil Science Society of ChinaElsevier, 2010-10-27)Soil aggregation and organic matter of soils from the pre-Pyrenean range in Catalonia (NE Spain) were studied, in order to assess their quality as carbon sinks and also to select the best soil management practices to ... -
Aggregate strength in calcareous soil fertilized with pig slurries
(British Society of Soil Science, 2017-07-13)Effects of applications of pig slurry on soil aggregate stability are not well understood in dryland agriculture. This research aims to (i) identify aggregate stability tests that give a reliable description of the soil's ... -
Agricultura de Precisión: ¿Qué se oculta detrás del nombre?
(New Ag International SARL, 2017-01-01)El término Agricultura de Precisión (AP) se ha discutido mucho durante los últimos años en exhibiciones y conferencias sobre agricultura, encuentros profesionales, revistas y cafés. Por otra parte también se usan expresiones ... -
Agricultural soil organic carbon stocks in the north-eastern Iberian Peninsula: Drivers and spatial variability
(Elsevier, 2019-02-22)Estimating soil organic carbon (SOC) stocks under agriculture, assessing the importance of their drivers and understanding the spatial distribution of SOC stocks are crucial to predicting possible future SOC stocks scenarios ... -
Ammonia emissions from different fertilizing strategies in Mediterranean rainfed winter cereals
(Elsevier, 2014)Anthropogenic ammonia (NH3) emissions mainly result from agricultural activities where manure spreading plays a significant role. For a Mediterranean rainfed winter cereal system there is a lack of data regarding NH3 ... -
