CALCIPRILL (GRANULATED CALCIUM CARBONATE)

Calciprill is prill made from very finely ground purity calcium carbonate.application is done to adjust soil PH. It is applied to tree crop, pasture and other crops. Calciprill is highly reactive and equally effective at rates 80-90 % lower than required by standard aglime. The rounded prills mean it can be applied, on its own or with additional fertilizer & seeds, by anyone with standard fertilizer spreaders.
Why use Calciprill
• Rapid pH improvement means rapid crop response
• Flexible application means less dependence on weather conditions
• Useful in precision agriculture
• Can be applied by air to steep terrain allowing utilization of all pasture
• Excellent source of calcium, an essential nutrient in plant cell structure
• Allows farmers to carry out regular soil maintenance Application Rates (0.1 pH Improvement)
Application rate depends on soil type, pH value, and crop.
