Kelzyme Calcium CAFE Micronized (35 lb pail)

Great Fertilizer for Adding Calcium

Calcium is essential for strong plant cell walls, healthy root growth, and quality fruit and flower production, and a micronized form allows for quick, efficient uptake. Kelzyme CAFE™ Micronized provides a fine, easy-to-mix powder sourced from ancient seabeds, delivering a highly available form of calcium carbonate and calcium oxide. With a guaranteed analysis of 35% calcium, it supports healthy plant growth while improving long-term soil fertility.

This ultra-fine texture makes it ideal for foliar sprays, fertigation systems, and soil drenches, allowing nutrients to be absorbed more rapidly than standard granular forms. It’s suitable for a wide range of crops and applications, including vegetables, fruits, flowers, shrubs, trees, turf, and vineyards. Regular use can help prevent calcium-related deficiencies such as blossom end rot in tomatoes and peppers while promoting overall plant resilience.

Because it’s naturally sourced and free from synthetic additives, Kelzyme CAFE™ Micronized is an excellent choice for sustainable gardening and farming practices. Its versatility and quick availability make it a valuable addition to both small-scale gardens and larger agricultural operations.
