Past research on grazing and stream management focuses on the arid western U.S. This report from Ontario, “analyzes and summarizes data to determine the extent and magnitude of phosphorus and bacterial loading to surface water quality by livestock with access to water courses and left to graze in pastures without supplemental feeding” (pg. 3). It also provides recommendations for how to research the impacts of pasture management on downstream attenuation, and develop appropriate management strategies that will balance surface water quality with cost effectiveness for farmers.

Written by Extension Service staff and Minnesota’s grazing specialist, this accessible manual takes a reader through the decisions required for a grazing management plan as the first step to transitioning into rotational grazing. Sections cover a resource inventory (goals, land, livestock, forages, water, fence), grazing plan development (the design of paddocks, fencing, water, and heavy use areas), pasture management (forage and
livestock, soil fertility, weed control, sacrificial paddocks), and monitoring/record-keeping. Ten appendices provide worksheets, grass identification keys, water system considerations, average forage yields for Minnesota and Wisconsin, and formulas to calculate reserve herd days.

Reed canary grass is an excellent choice to reduce streamside erosion in streams wider than four feet. In smaller streams, sedges should be used, while bluegrass, shrubs, and trees should always be avoided. Most streams will heal themselves with minimal intervention from land use managers. This extensive publication covers vegetation, in-stream alterations, spawning grounds, and flood control, with an emphasis on the natural and managed physical stream attributes that influence trout. Pages 11 and 12 cover measures to improve and protect stream vegetation, including many pictures of streams before and after treatments. Some construction projects are explained in detail and with excellent graphics, should it be deemed necessary to undertake them. Appendix A provides an index of commonly used physical and hydrologic terms. (Wisconsin Department of Natural Resources, Technical Bulletin 39. Madison Wisconsin. 65pp.) |

With careful management, dairy cattle can stay outside through the Wisconsin winter. Care must be taken to prevent frostbitten teats, provide adequate nutrition, keep animals clean, and provide a windbreak. Research Brief #28. The Center For Integrated Agricultural Systems |

Thirty-three management intensive rotational grazing dairy farms in Wisconsin were studied to determine the destination of nutrients, organic matter, and biological components in dairy cattle over-wintering areas. There were three basic management approaches used by farmers in the study: rotation through paddocks, sacrifice paddocks, and bedded packs. In all three situations, wastes produced could be controlled and managed to enhance pasture fertility, and waste could be kept out of the water cycle. |
