Our limestone comes from above ground limestone rock, and is crushed to a very fine powder. The smaller the particles in the powder, the more effective the lime is in reacting in the soil. For easier handling and application, the powder is then rolled into granules held together with a binding agent.
The binding agent used to make Dolopril™ is highly water soluble. Consequently, as soon as Dolopril™ granules come into contact with water, disintegration of the granule begins, and the many small particles that comprise the granule are released into the surrounding soil water medium and begin working in the soil.
Dolpril™ offers the following benefits to your soil:
- Provides sources of calcium (22%) and magnesium (11%) to the soil
- Raises the pH of acidic soil – reduces soil acidity and increases alkalinity
- Reduces excess aluminum, iron, and manganese
- Increases availability of major plant nutrients in acidic soils: nitrogen, phosphorus and potassium, plus molybdenum
The main difference between between DoloPril™ and CalPril™ is the % of Calcium and Magnesium they contain. The ideal ratio of Calcium to Magnesium is 6:1. DoloPril™ contains an approximate 2:1 ratio, so it is most used when soils have a Magnesium deficiency. Because of the 50% calcium carbonate contained in DoloPril™ it still benefits the lowering of soil pH.
Availability of primary nutrients is hindered in low pH (acidic) soils, with some plants, legumes in particular, not able to grow at all. Soils become acidic in areas of high rainfall due to leaching; after continual crop removal that promotes soil mineral loss; and in response to applications of chemical fertilizers.
