Nitrate leaching below the root zone was monitored and a water quality model was simulated for poultry litter application to pine seedlings. The six treatments used in this experiment were 4.5, 9.0, and 18.0 t/ha of poultry litter, 4.5 t/ha of poultr

A study was conducted to evaluate the feasibility of selectively harvesting broccoli by raking with spaced fingers to uproot plants having larger, marketable-size heads. Plant uprooting forces were unacceptably high under dry soil conditions. In subs
