The answer is, almost none.
Why? Because highly efficient plant-available sources are available. While the cost of these products on a per ton basis is many times higher than the ore they are derived from, the per acre cost is lower due to the efficiencies gained through the processing and pelletizing or granulation of these materials. This makes the product less expensive and more effective on a per acre basis than shipping and applying many tons of a low grade ore.
Wouldn't it be great if there was someone who manufacted a highly efficient, very pure lime or gypsum product?
Lucky for the farmer there is. SuperCal 98G is the highest quality, highest efficiency liming material avaialble for agriculture. SuperCal SO4 is the country's most effective gypsum product.
