Soil exchange association
WebNot everyone knows that plant roots have symbiotic relationships with certain types of fungi. These mycorrhizae help the plant absorb nutrients from the soil that are otherwise difficult to obtain and often provide some protection against soil-borne diseases. In exchange the plant suppliesfood to the fungus. To learn more about mycorrhizae, read this article... Webtypical exchange series in ascending order of exchange preference is as follows: Na+ < K+ < Ca2+ < Mg2+ < Al3+ (Grim, 1962). A good soil stabilizer should provide calcium ions (Ca2+) in sufficient amount so that the monovalent cations, especially Na+, adsorbed on the cleavage surfaces are replaced. This phenomenon is illustrated in Figure 1.

WebJul 31, 2024 · Soil pH, a measurement of the activity of hydrogen ions (H +) in soil solution, is a variable that drives many aspects of nutrient cycling and soil biology. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline. Most crops do best in the soil pH range of 6–7, though there are some exceptions.
