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 Calpril™ is highly water-soluble. As soon as Calpril™ granules come into contact with water, disintegration of the granule begins, and the many tiny particles which comprise the granule are released into the surrounding soil water medium and begin their work in the soil.

Calpril™ benefits soil in many ways:

  • Provides a source of calcium (36%)
  • Increases the pH of acidic soil – reduces soil acidity and increases alkalinity
  • Improves water penetration in acidic soils
  • Reduces excess aluminum, iron, and manganese
  • Increases availability of major plant nutrients in acidic soils: nitrogen, phosphorus and potassium, plus molybdenum

The primary reason for using lime is to correct the pH of highly acidic soils to improve plant growth and productivity. 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.
