Document Summary
Grasses: depend on the climate and the soil: ph: 6-6. 5, well drained soil vs clay, ambient temps/ rainfall. Cool season: higher in sugar and fructans, especially when they are growing fast (spring and early fall: timothy, orchard grass, fescue, ky bluegrass, ryegrass and quack grass. Warm season: lower in sugar and fructans: brome grass, bermuda grass, switchgrass and bluestem. Switchgrass: biofuel, grow really and really dense, not great horse feed. (bacteria) nitrogen fixation improves soil: white clover causes them to drool a lot, red clover is more nutritious. Toxic plants: bitterweed, black locust, cocklebur, horse tail, milkweed, pigweed, yarrow, st. johns wort. Management: ph maintained with lime, weed control, moving, spreading manure, don"t over graze, rotational grazing. Give different spaces to allow grasses to grow back after over grazing. Sheep rotation with horses has benefits bc sheep eat fungi larvae that can hurt horse.
