Compost Technical Data Sheets
Understanding Compost Technical Data Sheets
Since growing conditions and plant requirements vary, compost users can benefit from information that accurately characterizes the compost products they use. This data can help you to improve the way you use compost to best meet your particular
needs and to fit your specific situation. Fortunately, all STA Certified Compost products come with Compost Technical Data Sheet (CTDS) upon request, which includes a variety of measures of that compost. This provides transparency about the quality and composition of the compost and the uses for which it is most suited.

DOT Compost Technical Data Sheet
DOT’s in each state have a customized format for their CTDS Data Sheet in the STA Certified Compost program. Here are some examples. Beside each test result you’ll see the boundaries
of what that state DOT will accept for each value.
Test Characteristics and their Importance
As part of the STA certification process, each batch of compost is tested on a number of different characteristics including pH, plant nutrients, maturity and others. Those test results are reported in each Compost Technical Data Sheet for the benefit of the end user.

STA Certified Compost Ingredients (Feedstocks)
The materials that go into making compost (e.g. leaves, food byproducts, etc) are known as “feedstocks”. Click on the link below for general descriptions of feedstocks that could be used to create compost. Disclosing the feedstocks in each compost product to customers is a requirement for every STA Certified Compost product in the program, and is shown on CTDS.Read More
Directions for Use
Our native soil profiles vary greatly around the country, along with climatic conditions, OM (organic matter) content, local plants with their specific needs, and cultural methods. The directions compost manufacturers provide on their CTDS is customized to your area of the country and that compost manufacturer’s compost product. It would be unrealistic to expect that one set of directions will apply to every consumer and scenario, but good directions provide specific numbers and reasonable ranges.
