Soil dry aggregate stability and wind erodible fraction in a semiarid environment of Argentina
(2010-10)The size and stability of soil aggregates are primary factors that affect the soil susceptibility to wind erosion. Relationships among several soil properties and both the wind erodible fraction (EF) and the dry aggregate ... -
Soil physical changes after conversion of woodlands to pastures in dry Chaco rangelands (Argentina)
(2017-03)The conversion of dry woody rangelands into pastures can alter key soil physical properties that regulate ecosystem water circulation and storage. Based on three paired stands of native woodlands and pastures established ... -
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 ... -
Soil type affects biological phosphorus cycling more than soil management
(Elsevier, 2022-08-10)There is a need for more sustainable management of phosphorus (P) fertilization including reutilization of wastes and taking more advantage of the biological cycling of P in the crop-livestock-soil system to comply with ... -
Soil type, land-use and -management as drivers of root-C inputs and soil C storage in the semiarid pampa region, Argentina
(Elsevier, 2019-09-01)The objective of the study was to assess the effect of soil type, land-use and -management on root-C inputs and soil carbon storage in the central semiarid pampa region, Argentina. Twenty-one sites were assessed with ... -

Sorption, desorption and leaching potential of sulfonylurea herbicides in Argentinean soils
(2015-02-25)The sulfonylurea (SUs) herbicides are used to control broadleaf weeds and some grasses in a variety of crops. They have become popular because of their low application rates, low mammalian toxicity and an outstanding ... -
South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning
(Wiley, 2022-12)Livestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns ... -
Spectral indices from aerial images and their relationship with properties of a corn crop
(Springer, 2018-03)Identification of areas with similar restrictions to crop productivity could improve the efficiency to manage agricultural systems, guarantee stable yields, and reduce the effect of droughts in rainfed systems. The ability ... -
