After a soil test to identify the soil's biological, mineral, chemical and physical requirements, compost alone may not meet your nutrient requirements; your agronomist may recommend a blending solution to amend your soil's deficiencies and optimise production.
The soil may require adding a formula (ratio) of ingredients to compost to create a blend rich in trace elements, sustainable nutrients, carbon and microbiology.
Please discuss your requirements, as Biomix can blend as a "special order" to your needs.
