Biological Amendments

Home/Store/Biological Amendments

These products are based on microbes and their interaction with the soil and the plant. They help the plant assimilate nutrients, reducing the need for higher amounts of fertilizer and saving the grower money. They often come in the granular or wettable form and can be applied to the plant at various stages of plant growth.
