Secuencia de cultivos con predominio de soja: efecto sobre indicadores de calidad física del suelo.
(Asociación Argentina de la Ciencia del Suelo, 2020-12)El aumento en la frecuencia del cultivo de soja y de su monocultivo puede provocar disminuciones en la materia orgánica del suelo (MO) y afectar sus propiedades físicas. Sin embargo, prácticas de manejo como la fertilización, ... -
Sistemas de cultivo alternativos desarrollados por productores en el sudeste de la provincia de Buenos Aires
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-10-21)El proceso de expansión de la soja (denominado sojización) en la pampa argentina ha tenido como consecuencia la especialización de numerosas explotaciones agrícolas en el cultivo de soja. Sin embargo, muchos actores del ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Storing soybeans (Glycine max) in silo bags: economic outcomes and grain loss risk
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12-01)Silo bags have the potential to increase grain marketing efficiency and to give farmers additional bargaining power. However, silo bags are prone to tearing that can cause grain losses. This article assesses the economic ... -
Sustainable intensification of agriculture improves soil nitrogen in the argentinean humid pampas
(American Society of Agronomy, 2022-03-31)In the Argentinean Humid Pampas, intensification practices like crop rotation, cover crops (CC) and fertilization can improve soil nitrogen (N) balance. This study aimed to assess how intensification practices affect soil ... -
The effect of agriculture on topsoil carbon stocks is controlled by land use, climate, and soil properties in the Argentinean Pampas
(Elsevier, 2022-05)The conversion of native grasslands into croplands with a high frequency of soybean (Glycine max L.) in crop rotations has diminished soil organic carbon (SOC) stocks in the Argentinean Pampas. The aims of our study were ... -
The potential of glomalin-related soil proteins as a sensitive indicator of changes in different cropping systems in the Argentine Pampas
(Springer, 2023-03)The glomalin-related soil proteins (GRSPs) are currently used to describe different fractions of the protein, which are linked to the arbuscular mycorrhizal fungal activity and include the easily or total GRSP (named EE ... -
Tracking on-farm innovations to unearth alternatives to the dominant soybean-based system in the Argentinean Pampa
(2016)Las actividades agrícolas en la Pampa argentina tienen centrado en la producción de soja desde los años 1990. La resultante sistemas de cultivo pueden no ser sostenible en el largo plazo debido a la desarrollo de las malas ... -
Validation of a heat, moisture and gas concentration transfer model for soybean (Glycine max) grains stored in plastic bags (silo bags)
(2017-06)A two dimensional finite element model that predicts temperature distribution and moisture content of soybean stored in silo bags due to seasonal variation of climatic conditions is described. The model includes grain ... -
Water productivity in soybean following a cover crop in a humid environment
(Elsevier, 2020-02-05)We evaluated the influence of the termination dates of a winter cover crop on (i) soil water availability during soybean (Glycine max L. (Merr)) growing season, (ii) soybean evapotranspiration (ET) and iii) water productivity ...
