- R. Daren Harmel, USDA-ARS - Principal Investigator
- Rick Haney, USDA-ARS
- Monty Dozier, TAMU
- Doug Smith, USDA-ARS
Project Summary
- Poultry litter application rates 0 - 6 tons/acre
- Apply poultry litter to crop fields, pastures,
small plots
- 1m2 plots to small watersheds (3-21 ac)
- Research grant from TSSWCB
Project Objectives
Collect data on water quality, crop yields, and management to evaluate:
Runoff water quality (edge of field and downstream) Crop yield impact Economic considerations Scale differences Best Management Practices (BMPs) on small plots
