food wastes and many other organic waste streams have all been successfully
utilised in the production of food and fibre crops.
however, represent the greatest component of these recycled organics,
with over 1,000,000 tonnes being marketed by the company since its
inception. Biosolids may be described as the residual component
of wastewater treatment. Sometimes referred to as Black Gold,
biosolids are gaining increasing respect worldwideas natural soil
conditioners and fertilisers. The trend for this valuable growing
media may be in part attributed to extensive and long running research,
which has proven biosolids to be an excellent source of organic
matter and plant nutrients. Bio-Recycle has been able to offer biosolids
to the market place as dewatered cake direct from treatment works,
or as a value-added product from the companys N-Viro Soil
plants or bulk composting operations.
patented and licensed N-Viro technology is able to deodorise and pasteurise
biosolids through the addition of alkaline reagents. The result, N-Viro
Soil, offers farmers and horticulturists alike an organic liming alternative
for acid soil amelioration. Composted biosolids have also been successful
in providing an alternative for increasing soil organic matter.
the agricultural and horticultural markets, organics are recognised
for returning nutrients to the soil. In particular, processed organics
provide phosphorus and nitrogen in a slow release, or water insoluble
form, only releasing these nutrients slowly during natural decomposition
by soil microbes. Because of this slow release mechanism, many organics
may be applied in large quantities without risk of plant burn, soil
nutrient imbalance, or groundwater contamination.
large proportion of Australian soils are very low in organic matter
by world standards. Organics promote increased soil water retention,
improved soil porosity and air exchange around the plant roots, and
increased ability of soils to hold nutrients in a plant-available form.
In addition, the carbon: nitrogen ratio of organics, especially that
found within biosolids, is close to the 12:1 ratio considered optimal
for healthy agricultural soils.
