Pelletized Calcitic Limestone
Agricultural Industries have been using Calcium for years. It is one of our most important mineral ingredients but it is not always available in the quantities needed for our plants. Most soils today need extra calcium, even those soils which originated from limestone.
When the balance shifts towards calcium, soil porosity increases , plant roots function more effectively to greater depths, soil dries more quickly in spring or after rains, yet water can move more easily to the root zones during drier periods.
Microbes, (beneficial soil organisms), decompose organic matter and break down soil minerals to release nutrients to growing plants. Most microbes are aerobic, i.e. they require an adequate supply of oxygen. The population of important soil microbes is related to the calcium levels which enhances the oxygen supply.
Of the four main nutrients (calcium, nitrogen, phosphorous, and potassium), calcium should be ranked first. But because it is often over looked, it may be the limiting factor in plant nutrition.
Many people believe all limestone will increase soil pHs to levels that create nutrient unavailability. Limestone with high levels of calcium and low levels of magnesium will not raise the pH of soil to levels where nutrients are unavailable.
