UltraCal

UltraCal is a high-calcium limestone carbonate that is mined domestically. It is an effective soil conditioner for acidic soils. Formulated as a fine powder for bulk broadcast application, UltraCal absorbs quickly to restore balance in soil pH. This low magnesium mineral conditioner provides long-lasting soil benefits. It is a cost-effective solution for managing soil pH for multiple seasons.

Why is Calcium Carbonate Best For Neutralizing Acidic Soil?

UltraCal’s chemistry makes it an ideal mineral to neutralize acidic soil and promote crop yield. UltraCal calcium carbonate for soil features:

  • Calcium Carbonate Equivalent (CCE) of 101*
  • Fineness Factor of 100**
  • Neutralizing Index of 101***
  • *Determined by laboratory tests
  • **Fineness Index = 20% x (% of particles between 20 & 8 mesh) + 60% x (% particles between 60 & 20) + 100% x (% of particles passing 60% mesh)
  • ***Neutralizing Index = Fineness Factor x (%CCE/100)

Increase Yield for Corn, Alfalfa and Soybean

For optimum yields and nutritional value, soil pH must be maintained at a level suited for crops and future rotations. UltraCal is naturally high in calcium and low in magnesium to maximize crop nourishment for alfalfa, corn and soybeans. UltraCal is cost effective and efficient because of its soluble format, meaning you need less product to achieve the desired pH when compared with similar products.
