Soiltest has obtained a BW Max XT gas meter to measure compost pile oxygen levels in the field.  Used with an attached 7-foot probe, compost pile oxygen can be read rapidly.  This meter is also capable of detecting hydrogen sulfide and flammable gasses (% LEL).

Compost Testing at Our USCC Compost Testing Laboratory

If your business creates the essential ingredients for organic compost, you have the luxury of either using it for your own operations or selling it to a third party. No matter what its use, it is vital that your compost meet the quality standards as outlined by the US Composting Council.

At Soiltest Farm Consultants, we offer Tier I and Tier II analysis of organic compost at our Seal of Testing (STA) approved laboratory. Compost testing must be done by commercial and USCC-member compost producers to evaluate its quality and meet the guidelines set forth by state regulatory and permitting agencies. However, you do not need to be a member of the USCC to benefit from the expertise and benefit of our STA approved laboratory for your compost testing.

Some operations that will benefit from testing their compost include:

  • Municipal Yard Waste Composters
  • Confined Animal Feed Operations
  • Feed Lots
  • Hen Houses
  • Horse Boarders
  • Community Gardens & Master Gardeners
  • Organic Farmers

As the only STA Approved compost testing laboratory in the Northwest, we guarantee accurate results that you can depend upon. Additionally, we do Department of Transportation (WSDOT and ODOT) compost testing at our Soiltest Lab facility.

Organic Compost

People Often Wonder How to Compost – Here is a Basic Overview

Obviously, when someone asks how to compost it’s important to understand there are major differences between large and small scale organic composting. For large scale compost needs, such as a yard waste composting, a system should be set up that covers the following bases:

Site Selection and Preparation – Factors to consider for a compost site include size, slope, hydrology, erosion controls, accessibility, and a buffer zone to prevent affecting neighbors.

  1. Collection of Waste – Collection of waste is often the costliest part of creating compost. There are a number of compost collection methods, each with its own advantages and disadvantages depending on the type of operation you run.
  2. Processing – Much like collection, there are various means by which organic compost can be processed (the windrow-and-turn method is often used to process yard waste).
  3. Finishing, Storing & Testing the Compost – It is during this phase that we often test compost with our USCC approved compost testing analysis.
  4. Uses and Markets for Compost – There are a number of applications for compost, and it is always in demand from third parties such as farms, landfills, and recreation facilities.

Now that you know how to compost, it’s important to understand the goals of testing. You can more information directly from WORC by following this link.
