As an alternative, commercially readily available seed content may very well be employed. The seed correction mustn't exceed 1.0 mg/L BOD, as a result treatment must be taken not to employ as well strong a seed product to the test. The key to an excellent seed correction is a relatively secure seed content which makes a good seed correction in each and every test condition.
