The Ohio Pasture Measurement Project was started in 2005 as an attempt to help producers understand the value of timely measurement of their forages. The two objectives for this project are 1) to provide a source of current, objective information on the relative performance of forages growing in Ohio and 2) to demonstrate the use of pasture measurement/monitoring to aid in the management of grazing.  Initially, the project involved taking forage measurements weekly at three different farms in Ohio. In 2006, nine farmers cooperated, measuring 24 fields. The pastures measured contain typical forages found in Ohio pasture fields including: bromegrass, tall fescue, orchard grass, timothy, perennial ryegrass, Festulolium, bluegrass, reed canarygrass, and white clover. Management of the pasture fields including when to graze, clip or fertilize was up to the cooperating farmer. Measurements were taken weekly, from April through November, with additional measurements before and after grazing. Pasture growth was determined by a rising plate meter with calibration using clipping and drying 2'x 2’ quadrants. At each location a target residual level of forage was maintained in the pasture. Target residuals were 1200 lbs. DM/ac.  The average growth measured on the 24 fields during the months of April through November was 7,939 lbs. DM/ac. Predicted growth using the 3.5 ton average pasture production for the same months is 6,510 lbs. DM/ac. The range of the measured fields total DM production was 3,673 to 14,308 lbs. DM/ac. Trends from two years limited data show that Ohio grazers are able to manage and grow more forage from their pastures than the book values estimate. Growth per day for highly managed pastures can be very good in excess of 100 lbs. DM/ac/day. Pastures managed in the steepest part of the growth curve produced more than those allowed to grow for first cutting hay.
