Book Description
Rotational grazing tends be recommended over continuous grazing for its potential improvements to forage quality, yield, and animal gain. However, work comparing these grazing systems using horses is sparse, and it is not appropriate to utilize findings from other livestock species due to differences in equine physiology and grazing behavior. The present study examined the effects of grazing system on horse condition, vegetation attributes, and soil properties for one year. The first objective was to evaluate four methods for estimating plant species composition. Each method agreed with each other method well enough to be used interchangeably. The second objective was to compare the effects of rotational and continuous grazing on horse and pasture condition. Horses were not affected by grazing system, but pasture condition was strongly affected with rotational pastures exhibiting higher production and ground cover than continuous pastures. The third objective was to evaluate the effects of rotational and continuous grazing on soil chemical, physical, and hydraulic properties. It was found that grazing system had no effect on soil fertility, bulk density, or hydraulic conductivity. Overall, these findings support the recommendation of rotational grazing for improved pasture condition, but do not offer evidence of improved horse or soil condition over continuous grazing.

Book Description
Horse Pasture Management begins with coverage of the structure, function and nutritional value of plants, continuing into identification of pasture plants. Management of soil and plants in a pasture is covered next, followed by horse grazing behavior, feed choices of horses, management of grazing horses, and how to calculate how many horses should be grazing relative to land size. Management of hay and silage are included, since year-round grazing is not possible on many horse farms. A number of chapters deal with interactions of a horse farm with the environment and other living things. As an aid in good pasture management, one chapter explains construction and use of fencing and watering systems. Contributions are rounded out with a chapter explaining how the University of Kentucky helps horse farm managers develop their pasture management programs. - The purpose of the book is to help people provide a better life for horses - Provides the basic principles of pasture management for those involved in equine-related fields and study - Covers a variety of strategies for managing the behavior, grouping, environmental, and feeding needs of grazing horses to ensure high levels of welfare and health - Includes information on environmental best practices, plant and soil assessment, and wildlife concerns - Explains pasture-related diseases and toxic plants to be avoided - Includes links to useful resources and existing extension programs

Book Description
Some grazing methods can negatively affect water quality through increased phosphorus runoff, causing eutrophication of surface water bodies. High stocking density and poor forage stands can increase these problems. Rotational grazing schemes have shown promise in increasing forage stands and vegetative buffers. There is little information available involving the effects of equine grazing on a rotational grazing scheme. During 2007 and 2008, cool season grasses were grazed by horses of light horse breeding to determine the effects of rotational and continuous grazing methods, during the summer growing season. Plate meter readings were taken to determine available forage, grass clippings were taken from a 0.0929 m2 area to determine dry matter and calibrate the plate meter. The rotational grazing system showed higher available forage between the two treatments (P_0.01) for both years. However, year and interaction effects were not significant (P0.05).

Book Description
Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Book Description
Abstract : There is an increasing recognition of the importance of rangeland ecosystems as the source of water supply, wildlife habitat, recreation, carbon sequestration, and so forth, in addition to being a resource for animal production. Land holders and graziers are concerned about the decline in pasture productivity, as well as the environmental consequences of their practices. Continuous grazing practice has been largely documented to encourage selective grazing by animals, exposing desirable plant species to repeated defoliations as compared with less desirable or undesirable species that are usually ignored. Long term continuous grazing in rangelands ecosystems has also decreased the relative abundance of palatable plants, resulting in lower productivity. Surface soil compaction is often attributed to continuous grazing, due to trampling, lower infiltration, higher runoff and soil loss, as well as imbalanced distribution of urine and faeces across paddocks. Time- controlled (TC) grazing, which includes short durations of intensive grazing, followed by long rest periods, has been increasingly adopted by graziers around the world. It is believed that TC grazing reduces the negative effects of continuous grazing and increases pasture productivity. Although the new TC grazing system has received a high degree of acceptance amongst livestock producers over the last two decades, little research has been carried out to document the environmental consequences of such a grazing system. To address this issue, a comprehensive large scale field study was carried out on the effects of the two grazing management systems (continuous and time-controlled) on selected pasture attributes, soil characteristics, runoff and soil erosion from 2001 to 2006 on the grazing property, 2Currajong3, in the south-east region of Queensland, Australia. The results obtained show a highly significant herbage accumulation of up to 150% under TC grazing in 2006 compared with the earlier results following the change from continuous grazing to TC grazing in 2001. In continuous grazing however no such a significant change was found over the course of the study. In line with the results of herbage cover, ground cover and residue also increased with time under TC grazing but not under continuous grazing.

Book Description
Using vivid images and detailed explanations, Gerrish takes graziers step by step through the MiG system. He begins from the ground up with the soil, and advances through the management of pastures and animals. Written for those new to MiG grazing, Gerrish's insight and personal experience can help experienced graziers fine tune their grazing operations for added income.
