Agricultural Grade Perlite

Man's Hands Holding a Tree Seedling

Expanded perlite’s value to the growth and sustainability of the agricultural sector is increasingly recognized, despite more traditional uses for ornamental growing. Perlite is naturally weed and pathogen-free, and readily holds moisture and nutrients that are crucial to a plant’s development. Perlite is used in the silviculture industry, and for starting row crops such as hops, and in seed production requiring controlled conditions. It is used extensively for growing tomatoes, cucumbers, peppers, figs, micro-greens and more. Outdoor crops benefit from perlite-filled irrigation channels that conserve water and bring moisture and nutrients directly to plant roots.

Fine perlite can be used to hold onto moisture in regions with poor soil or that are prone to drought. Agricultural perlite for soil conditioning is spread and tilled into fields during rotation, or spread evenly with an application of compost.
