Data show that 15,000 lb/acre of dried sewage sludge induces more growth of loblolly pine seedlings after 2 years than 1000 lb/acre of 10-10-10 fertilizer combined with 2000 lb/acre of lime. Data also show: any subsoiling is better than disking; using fertilizer and lime, subsoiling to 18 inches was superior to 36 inch subsoiling; using sewage sludge, 36 inch subsoiling was superior; and roots grow freely in the subsoiled material. Biomass data indicate that twice as much weed and grass is produced on the sludge plots. Pelletized sludge with increased N was superior to pelletized fertilizer but not as good as broadcast fertilizer or sludge. 2 tables. (MF)
