"I like to say that when you buy an acre of land you get 43,500 square feet of solar panel. When you start thinking about your farm in these terms, the importance of having every acre covered with green, growing grass becomes apparent," Jim Gerrish writes.

Gerrish coined the phrase Management-intensive Grazing (MiG), putting the emphasis on management of the growth of the grass. The animals are merely harvesters, like lawnmowers. In Management-intensive Grazing, The Grassroots of Grass Farming, he uses vivid images and detailed explanations to take graziers step-by-step through the MiG system.

Written for those new to MiG grazing, Gerrish's insights and personal experience can help experienced graziers fine tune their grazing operations for added income. He begins from the ground up with the soil and advances through the management of pastures and animals, and covers how to manage the water cycle; how to work with legumes; how to stockpile forages for low cost wintering; how to plan and utilize permanent and perimeter fencing; and how to use pasture weaning for health and weight gain.

Gerrish's lively chapters explain how to make pasture fertility pay; the power of stock density; how to match forage supply with animal demand; how to judge maximum intake of forage; and how using pasture records offers information, not just data.

Jim Gerrish grew up on a grain and alfalfa hay farm in south-central Illinois. He spent over 22 years conducting beef-forage systems research and outreach while on the faculty of the University of Missouri. With over 20 years of commercial cattle and sheep production on his family farm in northern Missouri, he also has one foot solidly planted in commercial livestock production.

His research at the University of Missouri-Forage Systems Research Center encompassed many aspects of plant-soil-animal interactions and provided the foundation for many of the basic principles of Management-intensive Grazing.

Today, with his wife, Dawn, he contract grazes a commercial cow-calf operation on 260 irrigated acres in Idaho. He has received awards from the American Forage and Grassland Council, Missouri Forage and Grassland Council, National Center for Appropriate Technology, USDA-NRCS, the Soil and Water Conservation Society and others. He is also an independent grazing lands consultant providing service to farmers and ranchers on both private and public lands across the USA and internationally.
