Use our soil amendments to improve your soil structure and biological function. These organic and mineral substances enable you to create or rejuvenate a natural soil with all the nutrients and trace elements necessary for improved soil fertility. Once added microbes act upon these inputs converting them to plant available forms. Soil amendments are available to plants over longer periods of time making them slower to act than most liquid nutrients. Re-amending is an infrequent task, so is simpler than monitoring and adhering to feeding schedules. This saves you time to concentrate on other aspects of gardening.
