A field study was initiated 1 December, 1992 to evaluate the effects of soil incorporated newsprint, wood chips, yard waste or gin trash with an adjusted C:N ratio of 30:1 using poultry litter on weed control and cotton (Gossypium hirsutum L.) production in North Alabama. Each organic waste was applied at a rate to provide 12,632 lbs/acre of total carbon. Half of the treatments were planted to wheat (Triticum aestivum L.). Each eight-row plot was planted to notill cotton 7 May, 1993. Four rows received chemical weed control and the remaining four received mechanical weed control. Wheat alone allowed more winter weeds than any of the other covers. Combining wheat and the waste materials reduced winter weeds. Newsprint and gin trash were more effective in reducing winter weeds while wood chips and yard waste produced little or no effects. Cotton maturity and yield were not affected by the fall application of poultry litter or by any of the organic wastes. There was no evidence of reduced efficacy of pendimethalin, fluometuron or norfluarazon when applied preemergence. There was no difference in chemical or mechanical methods of weed control. Results suggest that cellulose waste materials have potential of being disposed of in agricultural soils . Continued research is needed to verify long term effects.
