Impacts
This project has contributed towards significant interest in grazing sysytems within Ohio. The number of grazing farms has increased with at least 20 new farms using dairy grazing during the study period. There has been renewed interest in the Ohio program for beginner grazers, with 20 "Beginning Grazing" courses being conducted throughout Ohio. There have been 6 Advanced Grazing Course also held. One significant finding was the result from 2007 of few differences between rotational and continuous grazing. This result, although reported in the literature, allows researchers to focus on aspects of grazing systems that do result in benefits to producers (even though greater production may not occur) One significant grazing tool that is gaining increasing interest is the rising plate meter. This simple tool has potential for on-farm use in quantifying forage biomass, and adjustments in the grazing system. At least 25 producers throughout Ohio are using rising plate meters as an adjunct to their grazing management. Regular data measurements are posted to the website: http://forages.osu.edu/ Detailed measurements of soil, plant and animal performance were made on the Coshocton field study during summer 2008. In a study at 2 adjacent field sites (Donn Scott & Coshocton) biomass growth curves were measured that showed an excellent representation of biomass accumulation by an asymptotic Gompertz relationship. One implication of this relationship is that biomass is, mathematically, an excellent predictor of growth rate. This result adds weight to current emphasis to farmer investment in pasture biomass monitoring (a key component of this project). A preliminary Excel model was developed that uses the pasture growth equations to predict likely impacts of variable biomass on forage production. This will be the basis for a) modeling comparisons of rotational and continuous stocking for future work, and b) modeling the grazing treatments in Part 1 of this study, during 2009. Farmer interest in this project (and the model development) remains high, with several presentations for local and state producer meetings. This project contributed to development and maintained of the website of the Ohio Integrated Forage team (Sulc): www.forages.osu.edu. Research findings, Amazing Graze articles and Blogs posted to website (Sulc) As the final year of this study, research focused on analysis and modeling; 9 research studies were conducted during 2010. Measurements during 2010 were consistent in support of 2008 & 2009 data, in providing evidence for the adoption of Gompertz to represent forage production. In 2010, our measurements were expanded from previous years to include forage quality. To address the concern that previous measurements of herbage accumulation included considerable mass with poor quality, we focused on developing Gompertz curves for digestible biomass. Preliminary analysis suggests that optimum biomass will be lower when considering digestible biomass accumulation rather than total biomass accumulation.

The Agronomy Journal paper has generated some interest from forage researchers. Since its publication, the authors have received several invitations to present the findings at technical workshops and meetings. A no-cost extension was granted at the end of the project for final forage quality analysis to get completed.

Progress 09/01/08 to 08/31/09
Outputs
OUTPUTS: This project conducted research and extension relevant to management intensive grazing to improve profitability of Appalachian hill-farms in south-east Ohio. Research during 09/01/2008 to 08/31/2009 comprised: 1) Conduct of a 56 ac grazing study with 32 cows at the USDA-ARS North Appalachian Experimental Watershed (NAEW), in Coshocton Ohio. Briefly, cow-calf pairs were divided into 4 groups and either rotational or continuously stocked to four pastures (2 replicates of two treatments). The responses measured included livestock and forage performance, and characteristics of the runoff water. 2) A graduate project (Ferraro) measured the relationship between forage growth rate and herbage mass, for four 'rotational' treatments for the three forage species (and a mixture) present in the NAEW pastures. (2 publications) 3) A graduate project (Nave) measured the relationship between forage quality and herbage mass, for typical 'cattle' pasture in Columbus OH. (1 publication) 4) A graduate project (Smith) measured the performance of 9 forage species (and 6 mixtures) under rotational cattle grazing in Wilmington OH. Extension during 09/01/2008 to 08/31/2009 comprised: 1) Invited technical presentations by project PI's to six meetings of producers and industry professionals 2) Four Grazing Schools were offered, with 149 participants. 3) Four web-pages/web-articles were produced for Extension media PARTICIPANTS: D.J.

Impacts
Changed Knowledge: A comparison of rotational and continuous stocking treatments showed relatively few differences in livestock performance. Total cow gain was 57.3 and 49.1 lb/acre, for continuous and rotational treatments. Calf weaning weight was similar for the two treatments, 558.5 and 551.0 lb/calf, respectively. Hay was made in the rotational treatment, averaging 4.9 tons/pasture, however this was not fed back to livestock, to extend the grazing season. The Autumn of 2008 had only half average rainfall and livestock were removed early from pastures. Additional experimentation was conducted to determine the mechanistic basis for forage responses to grazing. Pasture accumulation over time was fit to sigmoid curves. Derivatives of these equations showed the time-dependant response of pasture growth. Re-expression of these equations showed the time-independent relationship of pasture growth on herbage mass. One conclusion from the time-independent relationship obtained in this study is that it is not so much the forage defoliation method (rotational vs continuous) that affects overall forage production, but the result of defoliation on herbage mass and its impact on pasture growth that has the greatest effect on forage production. Farmer behavior: Four grazing schools were conducted during 2009, for a total of 149 producers. A survey of those producers found: 1) 61 (of 89 who responded) were able to use information from the grazing school to extend their grazing season by an average of 40 days in fall and 24 days in spring. 2) 75 (of 91 who responded) were able to improve farm production, by increased stocking rate (17), increased forage production (29), fed less hay (10), increased fencing (9), and various other methods. Additional profit increases resulted from; decreased feed costs (20), decreased fuel costs (14) and decreased animal health costs (6). 3) 16 (of 52 who responded) reported less stress, and 11 reported less labor.

Impacts
This project has contributed towards significant interest in grazing sysytems within Ohio. The number of grazing farms has increased with at least 10 new farms using dairy grazing in 2007. There has been renewed interest in the Ohio program for beginner grazers, with 10 "Beginning Grazing" courses being conducted throughout Ohio. There have been 3 Advanced Grazing Course also held. One significant finding was the result from 2007 of few differences between rotational and continuous grazing. This result, although reported in the literature, allows researchers to focus on aspects of grazing systems that do result in benefits to producers (even though greater production may not occur) One significant grazing tool that is gaining increasing interest is the rising plate meter. This simple tool has potential for on-farm use in quantifying forage biomass, and adjustments in the grazing system. At least 15 producers throughout Ohio are using rising plate meters as an adjunct to their grazing management.
