On-farm nutrient management has a key role in farm and industry sustainability, and in ensuring minimal off-site impacts occur.
Ameliorants are important to maintain productivity by addressing soil limitations. Mill waste products (mud/ash) can supply significant amounts of nutrients (and trace elements), Organic Carbon and sufficient Phosphorus for up to two crop cycles thus reducing fertiliser inputs. Mill ash can also be useful in assisting to reduce impacts of sodicity. The full value of mill mud is explained via the link below.
Lime is necessary for reducing problems associated with acid soils and improving soil physical conditions.
