| Abstract/Contents: | "A greenhouse pot experiment was conducted in which bermudagrass (Cynodon dactylon (L.) Pers.) was grown on Holtville silty clay and San Emigdio fine sandy loam soils, which were amended with aerobically (AEDS) and anaerobically (ANDS) digested sludges to supply N at 600, 900, and 1200 kg ha-1. Ammonium sulfate [(NH4)2SO4] was applied to other pots at rates to supply N at 300 and 600 kg ha-1. A second 600 kg N treatment as (NH4)2SO4 was applied in three split applications. All (NH4)2SO treatments received 60 kg of P as monocalcium phosphate (MCP). Cumulative yields of bermudagrass grown on aerobic sludge treatments were greater than those yields on anaerobic sludge treatments for both soils. Patterns of plant yields indicate that a large initial release of plant-available N occurred in aerobic sludge treatments relative to anaerobic treatments. Though not statistically significant, more N was accumulated by plants grown on aerobic than on anaerobic sludge-amended soils. On both soils, aerobic sludge-P was more plant-available than anaerobic sludge-P. Calculated recoveries of sludge-applied N and P showed little variation due to soil type at equal rates of sludge application. For both soils, 1 Mg of aerobic sludge or anaerobic sludge produced bermudagrass yields equivalent to those resulting from the application of 24-37 kg (NH4)2SO4-N and 7-10 kg (NH4)2SO4-N, respectively. Tissue concentrations of CD were below 9 X 10-4 mmol kg-1 for all treatments, and were not considered to be excessive." |
