Soil Phosphorus Concentration under the Canopy of Perennial Grasses of Different Successional Stages Exposed to Water Stress
(Taylor and Francis, 2008-10)In this field study, the effects of water‐stress, rainfed, or irrigated conditions on soil phosphorus (P) concentration under the canopy of the native grasses of semi‐arid Argentina (late seral Stipa clarazii Ball., early ... -
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 physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
(2018-09)This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ... -
Soil porosity characteristics and water movement under zero tillage in silty soils in Argentinian Pampas
(Elsevier, 2006-05)The objective of this study was to identify pore characteristics (quantity, distribution, stability and orientation of pores) that condition water dynamics under continuous zero tillage (ZT) on silty soils of the Argentinian ... -
Soil Properties and Bacterial Communities Associated with the Rhizosphere of the Common Bean after Using Brachiaria brizantha as a Service Crop: A 10-Year Field Experiment
(MDPI, 2023-01)Intensive agricultural farming practices, such as monoculture, require long bare fallow periods and the overuse of agrochemicals, which compromise soil health over time. Increasing plant diversity in agroecosystems with ... -
Soil properties of sugarcane fields controlling triazine leaching potential.
(CSIRO PUBLISHING, 2019-08-21)Atrazine and ametryn are pre- and post-emergence herbicides widely used in sugarcane fields. Both herbicides are characterized by their moderate to high mobility in soil and are regarded as a threat to hydrologic systems. ... -
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 quality effects on Chenopodium album flavonoid content and antioxidant potential
(2008)Antioxidant capacity, total phenolic content and flavonoid glycosides profile were compared in C. album samples grown in intensively cultivated (IC) and nondisturbed (ND) soils to evaluate differences in their nutraceutical ... -
Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ... -
Soil quality indicators selection by mixed models and multivariate techniques in deforested areas for agricultural use in NW of Chaco, Argentina
(2016-01)Soil quality (SQ) is a multidimensional concept based on the use of indicators. Indicators integrated assessment gives much more information than individual data and a select set of parameters; solve operational and economic ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 2015-08)Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ... -
Soil salinization in Patagonian meadows with different grassland condition
(2018-08)Patagonian meadows (locally named “mallines”) are wetlands that develop in the lower parts of the landscape, were runoff water accumulates, and organic and humid soils appear, contrasting with the surrounding steppe. An ... -
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 ... -
Soil variability and crop yield gaps in two village landscapes of Burkina Faso
(Springer, 2016-07)Low crop yields in the savannah zones of West Africa are commonly attributed to rainfall deficits and poor soil fertility. In this study, an assessment was made on how the position of fields belonging to different farm ... -
Soil volume and carbon storage shifts in drained and afforested wetlands of the Paraná River Delta
(2013-03)Wetland ecosystems have a high carbon storage potential as a result of high primary productivity and low decomposition rates dictated by water saturation. In the herbaceous wetlands of the Paraná River Delta, drainage and ... -
Soil water availability and water absorption by maize in sodic soils with high water table
(Elsevier, 2023-05)Context: Because of the increasing prices of commodities over the last decades, crops like maize (Zea mays L.) are being cultivated in lowland sodic soils with physical-chemical constraints, such as those having natric ... -
Soil water availability during spring modulates canopy growth and impacts the chemical and sensory composition of Shiraz fruit and wine
