Organic Carbon Pellets
Carbon-P – A cost effective product to supply soil organic carbon
The depletion of soil organic carbon in Western Australian agricultural soils has long been known to be a critical issue in the ongoing sustainability of cropping in Western Australia. Soils low in organic carbon are more prone to leeching applied nutrients into the water table and require more fertiliser over all.
Long term changes in cultivation have begun the increase in soil organic carbon in agricultural areas of Western Australia however additional carbon inputs are required to improve soils. Traditional composts have been poorly received in the broadacre regions due to the volume required to make substantial changes in the soil being cost prohibitive.
What is it?
Carbon Ag Solutions have been working alongside C-Wise and Bioscience to develop a cost-effective way of incorporating organic carbon into current farming practices. Carbon-P is a compost derived pellet designed to be used in broadacre cropping programs both as a nutrient source and as a soil ameliorant.
Composts are manufactured by allowing microbial activity to break down waste products that would otherwise end up in landfill into a highly valued product with many agricultural uses with high organic carbon levels and increased biological activity. By compressing these composts into a pelletised form rather than their original bulky composition there are easier able to be transported and used for agricultural purposes.
Carbon-P is a benign, fully organic product manufactured in Western Australia.
How does it work?
Using Carbon-P with tradition synthetic fertilisers allows Carbon-P to be placed alongside the seed at seeding, the carbon then in the soil supplied by Carbon-P allows the germinating plant better access to the nutrients supplied by the synthetic fertiliser. The soils supplied carbon are also better able to store moisture and have higher biological activity than untreated soils creating greater
Soil stability and biological activity..
Increasing biological activity in the soil allows for greater breakdown of crop residues, improves soils structure, helps to retain water quality by filtering nutrients and improves regulation of nutrient supply to the plant.
Benefits of Carbon-P
Increase soil organic carbon levels and soil health for greater plant productivity.
Carbon-P is a cost-effective source of carbon
Increased soil carbon levels can be used to offset carbon emissions through the governments Emissions Reduction Fund
Microbial diversity of Carbon-P
The Bioscience ARISA assay returns the total number of microbial “operational taxonomic units” (OTUs) or “species” for each sample (alpha diversity). It is generally accepted that a high biodiversity is indicative of a healthy soil, so the more microbial species that are present, the healthier the soil. The microbial diversity of compost was assessed for the Carbon-P product. The total number of operational taxonomic units was 396 which is relatively low compared to soils (usually 600 to 800 OTUs) but it included high numbers of potentially plant-beneficial bacteria such as Actinobacteria and Firmicutes.
