Effects of Sewage Sludge on Wheat Forage Production
Experiments were conducted in Avra Valley, Arizona, to study the use of digested liquid sewage sludge as a source of plant nutrients in the commercial production of green-chopped feed and hay from wheat. Wheat grown with the recommended amount of plant-available nitrogen from sewage sludge produced more green-chopped feed and hay than did wheat grown with the same amount of nitrogen from inorganic fertilizer. Wheat green-chopped feed and hay grown with sewage sludge and inorganic fertilizer had similar livestock feeding qualities. Fertilizing wheat with sewage sludge delayed maturity.
Effects of Sewage Sludge on the Yield and Quality of Wheat Grain and Straw
Experiments were conducted in Avra Valley, Arizona, to study the use of digested liquid sewage sludge as a source of plant nutrients in the commercial production of grain and straw from wheat. Wheat grown with the recommended amount of plant -available nitrogen from sewage sludge produced the same grain yield as wheat grown with the same amount of nitrogen from inorganic fertilizer. Wheat grain and straw grown with sewage sludge and inorganic fertilizer had similar livestock feeding qualities. Fertilizing wheat with sewage sludge delayed maturity.
