This test gauges compost maturity based on seed germination rates. To complete this test, you will need to send in 2 gallons of compost.
Interpreting results
Phytotoxins in immature compost will often kill seed embryos. Compare germination rate in compost to germination rate in the control group; 80 percent germination is considered satisfactory.A germination rate in the compost markedly lower than the rate in the control group indicates the compost is immature and needs further curing.
