Spatial variability of an Alfisol cultivated with sugarcane [PDF]
Ciencia e investigación agraria, 2011 La variabilidad del suelo ocurre debido a factores que actuan en varias escalas espaciales y temporales, naturales o antropicas. El objetivo del presente estudio fue evaluar la variabilidad espacial y la relacion de algunos atributos quimicos, mediante diferentes tecnicas estadisticas. El trabajo fue realizado en el municipio de Maracanau (CE, Brasil),

Late Pliocene lakes and soils: a data-model comparison for the analysis of climate feedbacks in a warmer world [PDF]
, 2013 Based on a synthesis of geological data we have reconstructed the global distribution of Late Pliocene soils and lakes which are then used as boundary conditions in a series of model experiments using the Hadley Centre General Circulation Model (HadCM3 ...

Scaling the saturated hydraulic conductivity of an alfisol [PDF]
Journal of Soil Science, 1989 SUMMARY Alfisols exhibit a high degree of spatial variability in their physical properties. As a result, it is difficult to use information on physical parameters measured at one location to model larger‐scale hydrologic processes. In this study, the saturated hydraulic conductivity,

Kinetics of potassium desorption by Alfisols of Greece
Communications in Soil Science and Plant Analysis, 1994 Abstract The kinetics of potassium desorption from solution to exchangeable phases was investigated on Alfisol Haploxeralf samples, which were first saturated with calcium in the form of CaCl2. Potassium adsorption was studied using 5, 25, 100, 125, 150 and 200 μgK/ml solutions and equilibrated for 10, 20, 30, 45, 60, 120, 180 and 1440 minutes. Soil pH
