The adoption of no-till instead of reduced tillage does not improve some soil quality parameters in Argentinean Pampas
(Elsevier Science, 2016-02)
No-till (NT) has been recognized worldwide as a more suitable system than tillage for enhancing soil quality. However, several concerns remain about its conservative nature, especially when it is performed either without ...
Application of abscisic acid promotes yield in field-cultured soybean by enhancing production of carbohydrates and their allocation in seed
(Csiro Publishing, 2009-09)
This study investigates the effect of abscisic acid (ABA) and gibberellin (GA3) applications on physiological and productive parameters in complementary experiments performed with soybean cultured in the field for 3 crop ...
Exploring improved pesticide management in sub-tropical environments with GIS-supported fate modeling
(Elsevier, 2006-12)
The sensitivity analysis of pesticide models to input parameters related to crop management practices supplies working hypotheses to improve pesticide uses and environmental quality. Parameters of pesticide models that are ...
Uso de efluentes líquidos de tambo para mejorar la fertilidad del suelo y productividad de los cultivos
(Asociación Argentina Ciencia del Suelo, 2014-12)
Un experimento a campo se realizó en Esperanza (Santa Fe) sobre un suelo Argiudol típico con el objetivo de evaluar el efecto de la aplicación de diferentes dosis de efluente líquido de tambo sobre la fertilidad del suelo ...

(Universidad de Buenos Aires. Facultad de Agronomía, 2018-06)
La ecofisiología de cultivos en Argentina tiene una amplia y reconocida trayectoria no solo en al ámbitonacional sino también internacionalmente a través de una importante cantidad de trabajos publicadospor distintos grupos ...
Evaluation of hazelnut and walnut oil chemical traits from conventional cultivars and native genetic resources in a non-traditional crop environment from Argentina
(Springer, 2020-02)
The oil content and oil-quality responses of several hazelnut and walnut cultivars were evaluated in a new, non-traditional crop environment in north-western Patagonia. Moreover, two Argentinean landraces were studied for ...
Short-term effect of cover crops on aggregate stability assessed by two techniquesCultivos de cobertura: su efecto en el corto plazo sobre la estabilidad estructural evaluada por dos técnicas
(Asociación Argentina de la Ciencia del Suelo, 2019-12)
Aggregate stability (AS) is a property closely linked to soil fluid movement. AS can be determined by different methods and canbe improved using cover crops (CC), but the short-term effect of this practice has been little ...
Soybean response and ion accumulation under sprinkler irrigation with sodium-rich saline water
(Taylor & Francis, 2013-04)
The magnitude of crop growth and yield depends on the salinity level, the toxic ions present in the irrigation water and the irrigation system used. In order to study the effect of sprinkler irrigation with salty water on ...
Soil quality and productivity under zero tillage and grazing on Mollisols in Argentina – A long-term study
(2017-12)
The growing global demand for food, fibers and energy has triggered a scientific and political debate on how to attain increasing land productivity without further degrading soils. The objective of this study was to quantify ...
Response of soil microbial communities to different management practices in surface soils of a soybean agroecosystem in Argentina
(Elsevier, 2010-12-03)
Argentina is the world’s third most important soybean producer; hence, there is an urgent need to preserve soil health by applying appropriate agricultural practices to maintain sustainable production in the upcoming years. ...
