Calcium Products

The Driving Force of Calcium Products

Calcium Products is a company dedicated to helping customers maximize soil fertility to achieve higher crop yields and superior turfgrass. With a central location for distribution, access to pure limestone and gypsum deposits in Iowa, and the ability to create pellets that have a good balance between solubility and hardness, we offer the best calcium-based fertilizers on the market to growers and turfgrass managers across the country.

Our purpose is driven by a set of core beliefs that define who we are and how we operate. Our belief in continuous improvement drives us to strive for excellence in every aspect of our business, from our customer experience and products to our operational performance. We believe in the value of strong, long-term relationships built on trust and clear communication, and we work hard to deliver on our commitments.

Our Products

Our products, 98G pelletized limestone and SO4 pelletized gypsum, are manufactured in Iowa, atop some of the purest limestone and gypsum deposits in the world. Though a majority of our product is used in the agriculture industry, we also manufacture smaller grade sizes for the professional turf industry.

98G is pelletized limestone, the most effective and consistent product to correct and maintain soil pH. It is a critical factor in healthy plant growth and works as a master variable in the soil, governing chemical and biological processes. Don't just correct your pH when you soil test, maintain it at a level to maximize your yield every year.

SO4 is pelletized gypsum, the superior sulfur source that delivers the right amount of sulfur, perfectly matching plant needs. It supplies a strong initial release of sulfur followed by a steady supply throughout the growing season, perfectly matching plant needs. Averaged over 67 trials across the Midwest, SO4 increases corn yield by 15.4 bushels/acre compared to no sulfur.

Spring is an excellent time to address soil acidity with 98G. Many areas have not been able to apply limestone this fall/winter due to challenging field conditions. Other areas have been more successful with field operations to date, but everyone is looking for ways to improve soil fertility.
