Biochar Super Compost (SF60) is the best soil improver. However, it is not a growing media, ie to be used on its own for potting up and container growing. For a Biochar Multi-Purpose Compost (ie growing media), please see our SF40 listing).
In our Biochar Super Compost (SF60) tests, we have seen an increase in plant and crop growth of 100% over the control soil. All plant growth testing is complex and it takes many test replications over a number of years before we will know the 'average' increase. We believe most users can conservatively achieve a +20% increase in luscious plants and tasty vegetables.
The biochar/colloidal humus matrix acts as a ‘sponge’ for water and essential nutrients – storing them ready for use. The ‘sponge’ matrix supports increased levels of soil microbes. Microbes (notably mycorrhizal fungi) can access the stored nutrients. They form symbiotic relationships with plant roots and supply nutrients to the roots. This mechanism leads to improved plant health and growth. (More detail via our SF60 FAQ blog post)
Apply 1 Kg/m2, this is about 10% ie 1 part SF60 to 10 parts soil.
The application and coverage can vary. For more detail on application rate calculations by area, volume and weight and tips on how to make your budget go further, please visit the application ratio blog. We also have a free Excel calculator if you need to work out accurate application ratios.
It is important to dig (or hoe) Biochar Super Compost (SF60) into the root zone.
SF60 can be stored in a cool dry place. Avoid direct sun and drying out
