Retrieval of Evapotranspiration from Sentinel-2: Comparison of Vegetation Indices, Semi-Empirical Models and SNAP Biophysical Processor Approach
(MDPI, 2019-10)Remote sensing evapotranspiration estimation over agricultural areas is increasingly used for irrigation management during the crop growing cycle. Different methodologies based on remote sensing have emerged for the leaf ... -
Análisis de variables biofísicas en cultivo de cebolla (Allium cepa) con fertilización nitrogenada mediante teledetección
(Asociación Argentina de Horticultura, 2020-12)La producción de bulbos cebolla (Allium cepa) requiere elevada cantidad de nitrógeno. Acorde a la demanda de la agricultura sustentable, el desarrollo de tecnologías de la información y la comunicación, permite mejorar la ... -
Panorama de las producciones vegetales intensivas de alimentos saludables – “Proalim Km 0”, en tiempos de pandemia por la Covid-19 – Parte 2 Preferencias de la producción, agroindustria, comercialización y consumo de diversidad de hortalizas
(Asociación Argentina de Horticultura, 2020-12-21)Las producciones de origen vegetal de alimentos saludables (PVIAS), particularmente las frutas y hortalizas, constituyen un grupo de alimentos de gran interés por los beneficios de su consumo, dada la importancia que tienen ... -
Intensive plant productions - “Proalim Km 0”, in times of a Covid-19 pandemic – Part 1. Predisposition of consumers of vegetables, fruits and medicinal aromatics to their production, agribusiness and consumption
(Asociación Argentina de Horticultura, 2020-12-28)Given the importance that, for the health of the population, an adequate consumption of products of plant origin has, and in order to have a diagnosis on the intensive vegetable production of healthy foods (PVIAS) of ... -
Spontaneous Gene Flow between Cultivated and Naturalized Vicia villosa Roth Populations Increases the Physical Dormancy Seed in a Semiarid Agroecosystem
(MDPI, 2021-05)Hairy vetch (Vicia villosa Roth) is the second most cultivated vetch worldwide being used as a forage and cover crop. As it is not domesticated, it displays several wild traits including seed dormancy. The physical seed ... -
Effects of Onion Residue, Bovine Manure Compost and Compost Tea on Soils and on the Agroecological Production of Onions
(MDPI, 2021-10)Organic solid wastes are rarely considered when planning for rural production in Argentina. Onion production in the low valley of Río Colorado (Buenos Aires) generates between 12,000 and 20,000 Mg year−1 of vegetal wastes ... -
Megachile rotundata (Fab.) as a potential agro-environmental conservation strategy for alfalfa seed production in Argentina
(Wiley, 2021-11)Alfalfa (Medicago sativa L. 1753) is one of the main forage crops of the world, and the availability of an adequate seed supply to farmers is one of the main concerns for the seed industry. The international alfalfa seed ... -
Towards Sustainable Dairy Production in Argentina: Evaluating Nutrient and CO2 Release from Raw and Processed Farm Waste
(MDPI, 2021-12)Mineralization studies are the first step in determining the usefulness of an amendment such as fertilizer, and are essential to creating guidelines for dairy waste management to help producers make informed decisions. Our ... -
Enhancing Sustainability in Intensive Dill Cropping: Comparative Effects of Biobased Fertilizers vs. Inorganic Commodities on Greenhouse Gas Emissions, Crop Yield, and Soil Properties
