Question: What does lime do for soil? (2021)

Calcium hydroxide (,hydrated lime,) is an alkaline compound that can create pH levels as high as 12.4. The high pH also provides a vector attraction barrier (i.e., prevents flies and other insects from infecting treated biological ,waste,). Because ,lime, has low solubility in ,water,, ,lime, molecules persist in biosolids.
