The aim of the present study was to determine long-term K release rates from soil by use of a modified resin method, where vigorous agitation and soil–resin separations were avoided to minimise the dissolution of the soil minerals. Resins saturated with Ca2+ or H+ were tested; Ca2+ because it is the most dominating cation on the soil exchange complex, and H+ Cited by: A cation exchange resin method for measuring long-term potassium release rates from soil Article in Plant and Soil (1) January with 38 Reads How we measure 'reads'.

Introduction. Potassium (K +) is an element essential for plant growth and its importance in agriculture is well recognized (Sparks and Huang, ).Although the distribution of K + forms differs from soil to soil as a function of the dominant soil minerals present, total soil K + reserves are generally large.

Soil K + is typically divided into four forms: soil solution K +, exchangeable Cited by:   Within the framework of this study, the influence of high exchangeable potassium percent (EPP) on the physical condition of the soil and on growth is evaluated, assuming the possibility of its improving the structure of the soil.

A greenhouse experiment with a grumusol of different levels of EPP was conducted. The soil was irrigated with equilibrium solutions of two Cited by: 9.

The percentage of non-exchangeable K release to CaCl 2 during h was also correlated with the ratio of mica in the coarse fractions to total mica in the whole soil.

Results showed that the Elovich equation adequately described the reaction rates of K release from surface and subsurface soils and suggested a heterogeneous diffusion by: Potassium (K) is considered a major nutrient element together with nitrogen (N) and phosphorus (P) for plant growth.

However, in contrast to N and P, K fertilizers are applied at a much lower rate, and less than 50% of the K removed by crops is replenished ore, large agricultural areas of the world are reported to be deficient in available K 2,3, by: 7.

Cation exchange capacity (CEC): The negative charge that develops on organic and mineral colloids is neutralized by cations attracted to the surfaces of these colloids.

The quantity of cations expressed in milliequivalents per g of oven-dry soil is termed the cation exchange capacity (CEC) of the soil. Future improvement of woody biomass crops such as willow and poplar relies on our ability to select for metabolic traits that sequester more atmospheric carbon into biomass, or into useful products to replace petrochemical streams.

Lead in drinking water results primarily from the release of lead through corrosion of lead-bearing materials in plumbing and distribution systems. Corrosion control is the most effective treatment approach for minimizing lead concentrations at the point of consumption (Health Canada, b).

In well-aerated soil, air in the soil is similar in composition to air above the soil. Poorly aerated soils contain a higher content of carbon dioxide and a lower content of oxygen than the atmosphere above the soil.

Aeration is important because plant roots and aerobic soil organisms consume oxygen and release carbon dioxide during respiration.
