Usage Recommendations
For agricultural use, apply dolomite to acidic soil based on soil test results. It can be broadcast and incorporated into the soil before planting or applied according to local recommendations. The application rate depends on soil pH, buffer capacity, crop type, and calcium/magnesium requirements. Do not over-apply, as excessive amounts may raise soil pH too high. Conduct a small-scale trial before large-area application. For industrial use, follow the relevant process requirements for ceramics, glass, refractory, building materials, and chemical applications.
