APPLICATION OF MUNICIPAL REFUSE AND LIQUID SEWAGE SLUDGE TO AGRICULTURAL LAND .2. LYSIMETER STUDY

To determine if agricultural land could be used simultaneously for crop production and waste disposal-utilization, a lysimeter study was conducted using liquid sewage sludge and unsorted, pulverized municipal refuse. Refuse (R) at 188 metric tons/ha and a 2. 3-cm depth of sewage sludge (S) were applied separately and in combination (RS). A double refuse-sludge rate left bracket 2(R S) right bracket and a control treatment (C) receiving no additions were also used. Treatments were applied in the fall of 1971 and 1973. The cropping sequence was winter fallow-corn (Zea mays L. )-winter fallow-spring barley (Hordeum vulgare L. )-winter rye (Secale cereale L. )-corn.
