Changes in soil chemical factors following rainfall and calcium chloride applications
As detailed in the Super Journal report, "Changes in soil chemical factors following rainfall and calcium chloride applications" (24 KB pdf document), calcium chloride, when applied during rainfall periods, can have a positive effect on soil quality, especially in high sodium soils (greater than 110 ppm and 6% of the total extractable cations) that also have excessive sulfur (greater than 800 ppm for ryegrass overseeded bermuda fairways). The potential problem of accumulation of chloride in the soil was not an issue under these conditions. The fact that overall soil salinity was not significantly reduced indicates that either more rain and/or additional applications of calcium chloride will be required before overall salts are reduced.
