which lime has largest impact on raising ph in soil
Raising pH The ideal pH range for soil is from 6.0 to 6.5 because most plant nutrients are in their most available state. Ifa soil test indicates a pH below 6.5, the usual recommendation is for the application of ground limestone. Inaddition to having the ability to raise pH, limestone contains calcium. Lowering pH Some soils are alkaline and have a pH above 6.5. Some fertilizers (ammonium sulfate, urea, and ammoniumnitrate) create an acid reaction in the soil, so they aid in lowering or maintaining a specific pH.
