The management of soils with excessive sodium and magnesium levels

Reading Time: 15 minutes

Soils containing excessive concentrations of sodium and magnesium can have detrimental effects on plant growth and productivity. These minerals can accumulate in the soil to high levels due to various factors, including irrigation with water containing high salt content, excessive application of fertilizers rich in these minerals, and the deposition of animal excreta from grazing animals, which contain significant amounts of sodium and magnesium.

Soil fungi connections

Reading Time: 2 minutes

Soil fungi increase security, awareness, and knowledge for those connected to them. Any soil management action that results in the breakage of these connections, such as tillage and fungicides, destroys the entire nerve system of the soil thus isolating plants and soil organisms from each other.
