Supports Healthy Growth for Fruit Trees
We offer calcium carbonate powder for fruit applications. This product is specially designed for fruit tree cultivation and fruit quality improvement. We use low-iron limestone as the raw material. It undergoes strict sorting, crushing, screening, and washing processes. Our factory covers over 20 acres and is equipped with advanced production facilities and a professional quality control team. We do not simply supply raw materials-we help improve fruit yield and quality. Our calcium carbonate powder for fruit is a valuable tool for growers.
Key Specifications and Agricultural Focus
We strictly control iron and heavy metal content to ensure the product is pure and safe for agricultural use. The table below lists our key specifications. We use only low-iron limestone ore to guarantee quality from the source. We test according to GB/T 19281-2014 to ensure the calcium carbonate content meets the required standard. Low iron content is our core advantage, ensuring higher purity and improved safety for plants. Our calcium carbonate powder for fruit is designed specifically for agricultural applications.

Suitable Particle Sizes for Different Uses
Different fruit trees and applications require different particle sizes. Our 8–16 mesh size is used in orchards for soil improvement. The 16–30 mesh size is suitable for spreading around the base of fruit trees. The 30–50 mesh size is used in the preparation of Bordeaux mixture for disease control. The 50–80 mesh size provides a uniform coating that can help extend fruit shelf life. The 80–120 mesh size dissolves well in water for foliar spraying. We support customized grading and can adjust both particle size and packaging according to your specific needs.
