- Good pasture condition is critical to a successful grazing system. Pasture quality may vary greatly from paddock to paddock or year to year, due to differences in management, environment, fertility, grazing pressure or animal species.
- Desirable species provide high quality and production for a large part of the grazing season. Typically the desirable forages are hardy grasses and legumes that regrow quickly. Undesirable species are those that are typically unpalatable.
- Plant diversity is important to maintain a productive pasture throughout the entire landscape and growing season. If only one kind of plant exists, diversity is narrow and production will be limited. If many plant varieties are present, diversity is broad.
- High plant density is important. Bare and open spots are unproductive and allow for weed encroachment and soil erosion.
- Rate of regrowth following grazing is critical to a productive sward. Desirable species should be healthy and growing at their potential.
- Legumes are an important source of nitrogen to pastures and improve quality and quantity.
- Severity and frequency of grazing are critical in maintaining productive pastures. Close and/or frequent grazing reduces vigor and density of desired species. Light use causes excessive residue buildup, blocks sunlight and reduces forage quality.
- Differences in species, plant maturity and stocking rates cause uneven grazing with some plants or parts of the paddock grazed heavily and others lightly. Uniform grazing results in all plants being grazed to a similar height.
- A woody canopy provides shade for animals but may result in uneven grazing, uneven manure distribution, trampling and erosion. A woody canopy also intercepts sunlight and competes for water and nutrients.
- Decaying plant residue provides nutrients and organic matter to the soil. Too much residue results in poor nutrient cycling. Too little residue results in excessive water run off or evaporation.
