Additional information

The half-life of LAB in soil that was treated with sludge was examined. Sludge was applied by subsurface injection into the soil of three farms in the UK, and samples were collected for analysis over 105 days. Results indicate that there was a 98% removal rate of LAB from the soil. The soil half-life was determined to be 15.3 days.
