Discover the power of Agricultural Pumice by Rocky Mountain BioAg® – your solution for enhancing soil structure and promoting plant health. This premium pumice is sourced with precision, offering a natural and sustainable method of improving aeration and drainage in your soil. The open, coarse texture is used to enhance soil porosity, providing a long-lasting solution for large-scale farmers and backyard gardeners alike.

The enhanced root development that comes with the use of pumice allows for better nutrient and water absorption by plants. Its natural insulative properties help regulate soil temperature to create an environment conducive to thriving plants. Additionally, the porosity of pumice provides an extra drainage mechanism, avoiding excess water and therefore cutting down on the potential for root disease. 

Pumice is a sustainable choice that is healthy for the earth, easy to use, and full of unique benefits for your plants. Agricultural Pumice is a staple for those seeking plant resiliency and a flourishing garden. Invest in the health of your plants today by ordering powerful Agricultural Pumice.

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.
