Cambios en la estabilidad estructural de un Mollisol tratado con Vinaza
(2009-11-19)
La vinaza, subproducto de la destilación de alcohol carburante, posee una elevada concentración de electrolitos y es empleada en agricultura como fertilizante. Algunos autores afirman que independientemente de este uso, ...
Cation nutrient reserves decline markedly under intensive cropping of Pampas Mollisols
(Elsevier, 2023-04)
The availability of exchangeable cationic nutrients in soils, such as calcium (Cae), magnesium (Mge), and potassium (Ke), is vital for crops growth and development. However, the concentration of these nutrients can be ...
Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina
(Elsevier, 2021-01-14)
The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ...
Critical bulk density for a Mollisol and a Vertisol using least limiting water range: effect on early wheat growth
(2013-01)
The least limiting water range (LLWR) integrates crop growth-limiting values based on easily measurable parameters such as soil water content and bulk density (BD) and has been validated as a valuable soil physical quality ...
Desarrollo de una metodología basada en reflectancia difusa para determinar carbono orgánico en suelos de la cuenca del chambo

A Rapid Chemical Method for Estimating Potentially Mineralizable and Particulate Organic Nitrogen in Mollisols
(Taylor & Francis, 2017-01)
The objective of this study was to obtain an indicator of labile nitrogen (N) through a cost- and time-saving procedure by evaluating the relationships among potentially mineralizable N (N0), particulate organic matter N ...

Sorption and Selectivity Sequences of Cd, Cu, Ni, Pb, and Zn in Single- and Multi-Component Systems in a Cultivated Chilean Mollisol
(TAYLOR & FRANCIS INC, 2010)
The heavy-metal sorption ability of soils is one of the most important factors that determine the fate of these contaminants in this medium of the biosphere. When heavy-metal containing soil amendments are land applied, a ...
