| The Blair Brothers Ranch is 12 miles north of Sturgis, SD in Meade County. The Blairs raise Black Angus cow/calf pairs. They started a management intensive grazing system with their yearling heifers during 1980. They chose yearling heifers to keep costs down. They also wanted to start small and make sure that the system would work. | |
| Using this system, the Blairs increased their stocking rate from 70-85 heifers to 125-140 heifers through the driest years since the 1960's. The pastures have also shown improvements with an increase in green needle grass and western wheatgrass. Hardpan spots are completely grassed over with western wheatgrass. After seeing how well the system worked, the Blairs started using the system with the cow herd. More cross fences, water pipelines, and tanks and tanks were installed. |
|
| The Blair Brothers have two separate grazing systems. One is at the home place. The other is at Ed Blair's place. The systems are about 2 miles apart. The do not rotate pastures during June while breeding using artificial inseminations (A.I.). The cattle at the home place (355 cow/calf pairs) are rotated on 3292 acres of grassland. The cattle at Ed's (164 pairs) are rotated on 1644 acres. The pastures are divided into paddocks ranging from 96 acres to 684 acres. |

The Blairs rotate the cattle based on pasture size and growth rate of the grass. The average grazing period is about 5-7 days, trying to leave 30 days of rest between rotations. Vegetation is native grasses, forbs, tame grasses, and introduced legumes. The soils vary from silty clay loams, clays on the level to sloping lands and overflow clays and silt soils in the lower drainage-ways. Some shallow gravelly soils are located on ridges and shale derived soils are on breaks in the southern and western parts of the ranch. |
| The main source of quality water is from a well with pipelines leading to tanks in several of the paddocks. Tanks are filled with water prior to moving to that pasture. During this drought season, the quality and quantity of stock water has not been a primary concern of the Blairs. Tanks are located between pastures so that one tank will serve two or three pastures. | |
