Advising Services

  

We provide advising materials being processed
or help develop new composting operations.

For background information on composting, visit the page
Technical information - Compost and compost tea.

  

   
 


Monitoring of Temperature


         We do on-site measurement of temperatures in a compost pile. 

Management of temperature is important to ensure
the temperature of the pile is in the optimum temperature range,
to prevent fires from occurring within a pile and to determine when a pile is ready for use.
        

 

   


Monitoring of Moisture

Moisture content is calculated from samples collected from
within different locations of the pile and dried at our lab.

Moisture control is important to ensure microbes necessary for composting
can survive and disease-suppressive microorganisms colonize the curing materials.
 

   

 


Quality Assurance

We conduct trials to ensure a compost pile is stable and ready to use.
We also use the Solvita Test for compost maturity.

For further information please see the Solvita website at www.solvita.com

Compost Tea

We can help design a recipe for growing compost tea
that is specific for your needs.

  How to Make Compost

     Composting is the biological decomposition of organic waste under controlled conditions.

     Moisture, temperature and aeration are three things that must be monitored and maintained during the composting process.
 
     Usually, three phases occur during composting:
       An initial hot phase of 1 or 2 days, during which the smaller material is rapidly degraded.
       A period of many weeks when temperatures reach 45 to 65șC and most microbes are killed.
       A final curing phase when temperature declines and the material is re-colonized by microbes.

     Materials properly composted will reach the hot temperatures required to kill the microbes responsible for plant diseases. However, materials not composted properly may still contain pathogens. If kept wet for too long, the materials can trigger root and stem diseases.

     The curing phase is important for natural disease suppression. After reaching peak heating, different micro-organisms naturally colonize the piles. They include many parasites of root rot pathogens, such as Bacillus, Flavobacterium, Streptomyces and Trichoderma.
