In the realm of modern agriculture, the efficiency of agrochemical applications is a critical factor for successful crop management. Surfactants, or surface-active agents, have emerged as vital components in this …
Physical properties of fertilizers: Fertilizer materials of very low water solubility generally must be ground to small particle size to ensure sufficiently rapid dissolution in the soil and utilization by …
What are biogeochemical cycles? Nearly 30 to 40 elements are required for the proper growth and development of living organisms. Most important of these are C, H, O, P, K, …
The fate of herbicide in soil: When herbicides are applied to the soil, only a small portion of herbicide is absorbed by the plant. The rest is being lost through …

Ion Uptake Mechanism (Contact exchange theory, CO2 exchange theory) Ion Uptake Theory Scientists have postulated many theories about adsorption of ions, among them following 2 are most important 1. Contact exchange theory. 2. CO2 exchange theory. 1. Contact exchange theory Contact exchange theory In 1951 aenni and his associates develop this theory. This is a process of direct ion exchange between root cells and soil colloids. They observe that cations of soil colloids are generally moving around their own shell and similarly H+ ions of root surface are also moving around their own shell. In this process, once upon a time when two shells are come in contact closely they overlap each other. Then the ions of these two shells, exchange each other. Result by, H+ ions are replaced by other cations. H+ [Root] + K+ [Clay] → K+ [Root] + H+ [Clay]. 2. CO2 …
