How does Omya Calciprill correct soil pH quickly? 

 

Omya Calciprill is made of ultra-fine particles of natural calcium carbonate, granulated for easy application. The granules break down rapidly in soil moisture, allowing the fine particles to disperse through the soil profile.

 

The large surface area of the particles reacts quickly with the excess hydrogen in the soil, leaving the exchange sites on the clay humic complex to be filled by the calcium ions. This reduces soil acidity and improves soil structure within the season of application.

Why is calcium nutrition important for crops?

 

Calcium is an essential nutrient for the formation of cell walls and membranes. A continuous supply of calcium is required by all growing crops, particularly at fruit set.

 

Omya Calciprill provides a readily available source of calcium nutrition throughout the growing season, preventing deficiency and protecting yield by improving disease resilience.

Relationship between Calciprill and disease

"Because the products are granulated, I can spread them over large working widths, speeding up the application process and reducing fuel consumption. I saw good results in the first year, so now I use Omya Calciprill regularly."

 

        - Michal Sobczak, Arable Farmer, Poland

How often should I use Omya Calciprill?

We recommend regular soil sampling to check pH levels in your soil, and then apply Omya Calciprill to raise soil pH  to the optimal level close to 7. Once soils are at the optimal pH level, Omya Calciprill should be used annually at lower rates to manage soil pH and maintain soil health. For specific advice to suit your circumstances, consult your agronomist.

What results can I expect with Omya Calciprill

Omya Calciprill is proven in independent trials to deliver highly efficient soil conditioning and calcium nutrition to crops.

"As the agronomist for Coopers Farm Supplies for the past 9 years, I find the Omya granulated products easy to use with less dust, allowing farmers to spread through a conventional cone spreader, eliminating the need to rely on contractors with large belt spreaders. This makes them a great fit for smaller landholders, enabling them to take ownership of their paddocks and do the spreading themselves. In conclusion, these products break down quickly, stimulate plant growth, and help feed soil microbes."
