  • Pasture managers view themselves as grass farmers and the livestock as a means of marketing the forage. The goal is to produce good-quality forage for as much of the year as possible and then choose livestock that best market it.
  • To maintain a productive plant community requires skillful management. Understanding animal: plant interactions and their influences on overall pasture production is key.
  • In setting production goals, consider the economic return per acre rather than production per animal. Compare production per acre or per dollar invested into the pasture.
  • Most cow-calf operations have lower nutritional needs than do stocker enterprises. If high-quality forage can be consistently produced, a stocker enterprise may be a good economic option. Different classes of cattle, horses, sheep, or goats might be more suitable for the feed source and management.
  • Time controlled grazing has become popular and improves profits. Pastures are divided into paddocks where the land is grazed for short periods of time and the livestock is removed to ensure the plants have adequate time to recover before being grazed again. Because this requires more knowledge of forage plants and pasture-animal interactions, controlled grazing is often referred to as management-intensive grazing (MIG).
  • Grazed pastures need less fertilizer than those that are hayed. Animals use very few nutrients from the plants they eat as most minerals are returned in animal manure and become part of a natural cycling of nutrients. When manure is evenly distributed throughout the paddocks and earthworms, dung beetles, and soil bacteria are active, nutrients will be recycled quickly.
  • Soil tests and forage analysis are useful to monitor mineral nutrients in the soil and whether nutrients are actually being used by the plant. Results include fertilizer recommendations based on field history and planned use. Recommendations may not be accurate for pasture because they may not account for the recycling of nutrients by the grazing animals.
  • Producers are best able to evaluate fertilization needs based on their observations of productivity and nutrient cycling in their paddocks and using the soil test to monitor changes in soil chemistry and nutrient levels.
  • Legumes in the mixture increase soil fertility, improve overall feed value and extend the grazing season. Bacteria that live in nodules on the legume roots capture atmospheric nitrogen and after the nodules separate from the roots or the plant roots die, this nitrogen becomes available to nearby plants.
  • In order for legumes to persist in a pasture, manage the grass-legume mix for the legume. Grass must be kept short enough so that legumes are not shaded out. Fertilize for the needs of the legumes to avoid excessive competition.
  • Many organisms live in a healthy soil ecosystem. Root systems cooperate with underground animals in a complex, highly organized system very similar to the one aboveground. The soil biological community includes large populations of bacteria, fungi, nematodes, mites, and microscopic animals.
  • With continuous grazing, animals graze the most palatable plant species frequently. Root reserves are eventually exhausted and the plants die. In a controlled grazing system, animals only have access to small parts of the pasture at one time. Once grazed, plants are allowed sufficient time to regrow and to restore their root reserves. Over time the plant community becomes more diverse.
  • A sustainable pasture plan should be based on animals harvesting forage for themselves as much as possible. When pastures produce more than livestock can use, forage banking is one strategy to extend grazing into the dormant season.
  • In a controlled grazing system, livestock assist in managing weeds. Because cattle have access to the paddock for a short period, their grazing is less selective. Weeds provide good nutrition while they are in young, tender growth stages, which cattle would reject when mature.
  • Grazing different kinds of livestock improves weed control. Sheep and goats will complement grass-eating cattle by consuming broad leaves, blossoms, and seeds, while goats prefer brushy vegetation high in cellulose.
