Derived from the richest source of agronomically effective and organically certified plant active humates. It is known that humates work best when applied continuously during the growing season. Diamond Black is the only granular Leonardite proven soluble during a single season. Humates released into the plant's environment regulate the flow and enhance the transport of plant nutrients. Blended with rooting media, Diamond Black will slowly break down adding Humates to the root environment. This is a pure mined material and meets all organic standards for crop production. Hundreds of University studies have proven Humates increase plant growth and yield.
