Denitrification is the only reaction capable of removing the tremendous quantity of nitrogen applied when high-rate land filtration systems are used for renovating sewage water. This study determined that a shortage of organic carbon limits denitrification, and the effects of increased dissolved organic carbon concentrations on soil clogging and movement of fecal coliform bacteria are clearly shown. Finally, the removal of dissolved organic carbon at different carbon concentrations during high rate soil filtration (40-50 cm/day) also limits denitrification.ISSN

Response of Barley and Wheat to Sewage Sludge Loading Rates(College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)A greenhouse experiment was conducted to evaluate the responses of barley and wheat to sewage sludge loading rates of 150 to 750 lb /acre plant-available N and to recommended inorganic N (150 lb/ acre). All sewage sludge rates delayed maturity in both barley and wheat. Sludge loading rates up to 450 lb /acre of plant-available N increased vegetative growth and grain yield in both crops. Sludge rates higher than 450 lb/acre of plant-available N resulted in a reduction in the number of plants per pot; however, the stand reduction was greater for wheat than for barley.

Barley Grain Grown with Dried Sewage Sludge(College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)A four-year experiment, conducted at the Mesa Agricultural Center, studied the use of dried sewage sludge from the City of Phoenix as a source of plant nutrients in the commercial production of barley grain. The objective was to compare the effects of sewage sludge and commercial fertilizer on barley growth, grain yield, and quality. Three fertilizer treatments were used: (1) suggested rates of nitrogen (N), phosphorus (P), and potassium (K) in Arizona; (2) dried sewage sludge to supply plant-available N in amounts equal to the suggested rate; and (3) N, P, and K from inorganic fertilizers, in amounts equal to those in sewage sludge. Characteristics of barley growth, grain yield, and quality were similar for the three fertilizer treatments. Barley can use the fertilizer nutrients in dried sewage sludge to produce grain as effectively as it can utilize the fertilizer nutrients in inorganic fertilizer.
