Project Number: 6022-63000-004-01
Start Date: Jul 01, 2012
End Date: Jun 30, 2017
Management practices will be evaluated that optimize the proportion of landscape/small farm in pasture with buffers and trees to maximize environmental and economic returns. Effects of trees and buffers on runoff and water quality will be evaluated to reduce off-site environmental impacts. Poultry litter will be applied each year on watersheds that are hydrologically isolated with earthern berms and equipped with flumes and automatic water samplers. There will be five treatments: (1) overgrazed, (2) rotationally grazed, (3) rotationally grazed with grass buffer strip, (4) rotationally grazed with riparian buffer strip, and (5) hayed. Each treatment will be replicated three times. Concentrations and loads of antibiotics in runoff will be measured from every rainfall event that results in runoff.
