Feed your soil microbes and support plant health with Perfect Blend Organic Calcium 2-2-1 fertilizer. Whether you're planting crops or a backyard garden, this fertilizer will give you plentiful and beautiful yields. 

Our proprietary process creates a rich 15 percent calcium fertilizer with complex nutrition, allowing it to feed plants and soil microbes simultaneously. In addition, every ingredient goes through a thorough three-step purification process to ensure purity and quality standards, preventing weed seeds, pathogens, or insect casements and eggs from appearing in the final product.

Perfect Blend Organic Calcium Fertilizer is pH balanced between 6.0 and 6.1 to maintain pH balance and promote rapid growth of microbes in the soil. The homogenous granular blend can be used in bulk, on established turfgrass, as a starter, in ornamentals or raised beds, with transplant crops, as a top dress, or in base potting soil.

    I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
