Petunia

Compost and substrate testing

This is an important part of our business and we carry out trials for a range of clients. These trials are usually glasshouse based but some involve growing container plants outdoors. Seedling studies using parsley or basil and young plant studies using petunias, pansy, antirrhinums, tomatoes or cabbage can help identify the suitability of composts for amateur or professional use.

STC are also involved in testing green compost as part of the BSI PAS 100 test looking at the plant growth and weed seed levels. We also carry out the compost stability test measuring the CO2 levels produced by the green compost materials.
