Municipal sewage sludge, amended with Eucalyptus tree trimmings and composted, is being evaluated in San Diego as a soil amendment for field and greenhouse plantings of onion, snapdragon, turf and spinach. So far, increases in yields have been significant. In greenhouse studies comparing compost containing Eucalyptus trimmings with heat-dried sludge, results show both materials equally beneficial to crop growth. The presence of Eucalyptus did not decrease yields.
