What Are The Benefits of Grazing Management? Producer Benefits � Increased production per acre- increased energy efficiency � Increased organic matter � More available water � Drought tolerance � Lower cost � Less hay needed � More cow comfort Society Benefits � Improved water quality- lower cost to purify water � Improved soil quality- cheaper than CRP and better soil � Reduced flooding � Less CO 2 emissions � Lower temperature of environment � More energy captured

Methods Two similar orchardgrass plants were chosen from greenhouse. � Both were managed the same for 6 months: � �Clipped ~once per month �Supplied with good fertility (N, P, K) and water

Methods � Left plant simulates continuous grazing. � Initially clipped to a 1 inch

Methods � Left plant simulates continuous grazing. � Initially clipped to a 1 inch height � Then clipped weekly for the next 4 weeks at a 1 inch height � Right plant simulates rotational grazing. � Initially clipped to a 3. 5 inch height � Then clipped again at 3. 5 inches four weeks later � Time lapse photography started at the beginning of the fifth week (day 29) for both plants.
