Cation Exchange Capacity and Base Saturation
What are Cation Exchange and Cation Exchange Capacity? Soil clay minerals and organic matter tend to be negatively charged, thus attracting positively charged ions (cations) on their surfaces by electrostatic forces. As a result, the cations remain within the soil root zone and are not easily lost through leaching. The adsorbed cations may easily exchange with other cations in the soil solution...
متن کاملAn Improvement in Cation Exchange Capacity Estimation and Water Saturation Calculation in Shaly Layers for One of Iranian Oil Fields
Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. Additionally, in shaly sand formations this assumption may not be true as the ion...
متن کاملAssessment of spatial variability of cation exchange capacity with kriging and cokriging
Cation exchange capacity (CEC) is one of the most important soil attributes which control some basic properties of soil such as acidity, water and nutrient retaining capacity. However, the measurement of cation exchange capacity in large areas is time consuming and requires high expenses. One way to save time and expenses is to use simple soil covariates and geostatistical methods in mapping CE...
متن کاملUse of Diffusion to Determine Soil Cation-Exchange Capacity by Ammonium Saturation
Soil cation-exchange capacity (CEC) is often determined by NH4 saturation, using a 1M solution of NH4C2H3O2 at pH 7. A study was conducted to ascertain whether this determination can be performed by employing a simple diffusion technique previously developed for direct inorganic-N analysis of soils. Values obtained for 10 diverse Illinois surface soils following overnight NH4 saturation were co...
