Abstract/Contents: | "One of the factors limiting the rate at which sewage sludge can be applied to soil is the speed at which inorganic N is formed and the fate of that inorganic N. A greenhouse lysimeter study was initiated in order to quantify some of the sinks into which N from sludge applications might move. For 12 weeks soil columns were treated at 3-week intervals with a surface application of 2.5 cm of liquid sewage sludge. During each 3-day interval 2.5 cm of water was applied to: (i) soil receiving no sludge (Soil-2.5), (ii) soil receiving sludge (Sludge-2.5), and (iii) soil planted to Coastal bermudagrass (Cynodon dactylon L. Pers.) receiving sludge (Grass-2.5). Five centimeters of water was added to soil + grass + sludge (Sludge-5) during each 3-day interval. Another treatment was used to encourage a nitrification-denitrification cycle. This treatment (Grass-F) was identical to Grass-2.5 except that during each third week sufficient water was added to bring the 3-week total to the same as that in Grass-5. Provisions were made to collect the leachate for NO3-N analysis and to measure NH3 volatilization from the sludge. The average loss of N as NH3 was 36% of the applied NH4-N in the Soil-2.5 treatment and 24% in the three grass treatments. This represented 4.9 and 3.3%, respectively, of the total N applied. The Grass-5 treatment resulted in the maximum NO3-N leaching loss (5.4% of the applied N). The Grass-F treatment did not result in reduced NO3-N leaching. Grass removed 10.3% of the applied N. From 52 to 64% of the applied N remained in the sludge crust on the soil surface." |
