Agriculture dolomite

Dolomitic limestone, often referred to as ‘do-lime’, is a mixture of both calcium and magnesium carbonates. Do-lime should be used on soils with a magnesium soil test of 100 ppm or less. It is an excellent and inexpensive source of magnesium for acidic soils. On soils with a magnesium test greater than 100 ppm ag-lime or do-lime may be used.
