Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier Science, 2015-12)
Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...
Algunas propiedades del suelo que condionan su comportamiento: El pH y la conductividad eléctrica
(EEA Bariloche, 2020-08)
Cuando se solicita un análisis de suelo, los primeros parámetros que se suelen recomendar son el pH y la conductividad eléctrica. Sin embargo, a la hora de analizar los resultados en conjunto, suele prestarse más atención ...
Carbon Stocks and Isotopic Composition of the Organic Matter in Soils Covered by Native Vegetation and Pasture in Sorocaba, SP, Brazil
(UNIV TEHRAN, 2009)
Land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. The goal of this study was to compare the carbon stock and the isotopic signature of the organic ...
EFFECTS OF STERILIZATION AND TEMPERATURE ON THE DECREASE KINETIC OF PHOSPHORUS BIOAVAILABILITY IN TWO DIFFERENT SOIL TYPES

Changes in soil pH and addition of inorganic phosphate affect glyphosate adsorption in agricultural soil
(Wiley, 2022-02)
Glyphosate is the most widely used herbicide in Argentina. The strong sorption of glyphosate to the mineral fraction of the soil can be affected by environmental conditions and agricultural management, such as the application ...
Laser-induced breakdown spectroscopy: Extending its application to soil pH measurements
(2015-06-23)
Acid-base equilibria are involved in almost all the processes that occur in soil. The bioavailability of nutrients for plants, for instance, depends on the solubilization of mineral nutrients in the soil solution, which ...
Automatic Recovery Estimation of Degraded Soils by Artificial Neural Networks in Function of Chemical and Physical Attributes in Brazilian Savannah Soil
(Taylor & Francis Inc, 2019-06-27)
The Oxisols is predominant in 54% of Brazilian territories and characterized by high weathering, relatively low chemical properties, and adequate structure. This study aimed to analyze the Oxisols through an Artificial ...
