Lime Grit is a coarse lime by-product of the precipitated calcium carbonate (PCC) production process. PCC is used as a whitener at paper mills. The coarse nature of Lime Grit provides a gradual release of lime value over time, and is ideal for maintaining optimum pHs in well-managed fields and sweetening the soil of forgotten fields.
- pH: 12.4 (average)
- Calcium: 431 lbs/ton
- Magnesium: 16 lbs/ton
- Lime equivalence: 2.2 tons of Lime Grit is equivalent to 2 tons of commercial lime
Lime Grit is spread through typical lime or fertilizer spreading equipment at rates of around 2 tons/acre. Actual application rates should be determined based on crop need and soil test results. Available in Central Maine.
An application of 2.2 tons/acre of Lime Grit is approximately equivalent to the liming value of two tons of commercial lime.
