project objectives To investigate the use of cotton-processing wastes as organic soil amendments for cotton production. Establish field-trials with composted gin-trash to: a. determine effects on cotton growth and yield. b. assess effects on essential soil properties. To conduct a field-assessment of organic-wastes as soil amendments in cotton production: a. design and establish field-trials in collaboration with a commercial cotton producer. b. apply prescribed rates of worm-composted organic-wastes prior to sowing. c. monitor responses in cotton at critical stages of growth. d. determine the cost-benefit of processing wastes for reuse on cotton soils
