(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 ... -
Agrowaste compost as a component of substrates for ornamental plants = Compost de agroresiduos como componente de sustratos para plantas ornamentales
(ASAHO, 2022-01)The formulation of substrates for ornamental plants in containers implicates a compromise between physicochemical and biological characteristics, costs, andenvironmental impact for the use of peat. A way to optimize this ... -
Climate effect on Avena fatua field emergence dynamics: a 38-year experiment in the Semiarid Pampean Region of Argentina
(Wiley, 2022-02)Climate events modulate weed population dynamics mainly by influencing field seedling emergence patterns. Field experiments aiming to study the influence of climate on the early-stage establishment of weeds are of utmost ... -
Producción de forraje y densidad de plantas de alfalfa irrigada comparando distintas densidades de siembra
(Asociación Latinoamericana de Producción Animal, 2002)La alfalfa es la forrajera principal en el valle bonaerense del Río Colorado, Argentina. Sin embargo, se carece de datos locales sobre la densidad de siembra (den. smb.) que asegure elevada persistencia y producción del ... -
Curvas de crecimiento de forrajeras templadas irrigadas
(Asociación Latinoamericana de Producción Animal, 2001)Con el objetivo de construir y comparar las curvas de distribución estacional de forraje de 15 gramíneas y leguminosas se realizaron cuatro ensayos entre 1996 y 1999. Cada uno constó de dos repeticiones compuestas cada una ... -
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 ... -
