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

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,

Journal of Degraded and Mining Lands Management, 2021 Salinity of soil and irrigation is a factor that may cause a decrease in shallot productivity, so it requires efforts with amendments. This research aimed to determine the effect of gypsum and zeolite amendments on soil and shallot growth with saline ...

Kinetic study of phosphorus desorption by Alfisols and Entisols
Communications in Soil Science and Plant Analysis, 1993 Abstract The kinetics of phosphorus (P) desorption by six Greek soils, four Alfisols and two Entisols, have been studied. By the addition of several amounts of P fertilizers at different water/soil rations and different contact times, that amount of P fertilizer required for the two major categories for Greek soils in order to avoid enviromental ...

Geochemical Fingerprint and Soil Carbon of Sandy Alfisols [PDF]
Soil Systems, 2019 Soil carbon storage is affected by particle-size fractions and Fe oxides. We assessed soil carbon concentrations in different particle-size fractions, determined the soil chemical composition of the soil, and weathering and mineralogy of sandy soils of the Wisconsin Central Sands, USA.

Irrigation management in Pigeonpea under rainfed Alfisols [PDF]
Journal of Pharmacognosy and Phytochemistry, 2020 Pigeonpeais one of the major crops and grown in an area of 67,547 ha in drought prone Ananthapuramu district. However due usage of the long duration traditional Pigeonpea varieties and continuous failure of the NE monsoon coincides with the crop critical stages (Flower bud initiation, flowering, pod development in the district are the major drawbacks ...
