  • In pastureland, grazing management is the most important factor affecting stand health. The frequency of re-grazing of individual plants and the length of recovery will influence the direction of plant succession. Until this is addressed, no other aspect of rejuvenation will maintain healthy stands.
  • The use of fertilizer or manure to improve production and longevity should be based on recommended application rates considering fertilizer use efficiency, availability of nutrients in the soil and soil moisture.
  • Under the right condition, fertilizer application can be one of the most cost-effective methods to improve forage yield and quality.
  • Breaking and re-seeding is one of the most commonly used forage stand rejuvenation methods in western Canada. However, at least one year of forage production is lost through this method. If moisture conditions are not favorable, it can take more than one year to re-establish the forage stand.
  • Sod seeding is the direct seeding of forages into an existing perennial forage stand without any breaking and discing in order to improve species composition. The use of non-selective herbicide is necessary to suppress existing vegetation to achieve successful forage establishment.
  • The use of herbicides to control weeds prior to emergence of legumes and grasses will ensure successful forage stand establishment.
  • The use of herbicides to control woody re-growth, brush expansion and poisonous plants is an important management tool in stand rejuvenation.
  • The selection of suitable perennial forage varieties can improve soil condition.
  • Sward composition is an important consideration when deciding on the types of forage mixture and the seeding rates. Include appropriate mixture of grass and legume varieties suitable to the soil type and local growing conditions.
  • Legume-grass stands require much less nitrogen fertilization if the legume is properly inoculated with proper bacteria (Rhizobium). Bacteria that grow in root nodules are able to take up nitrogen from air and convert it to nitrate nitrogen for plant use.
  • Legume seed coated with R. meliloti for alfalfa, R. trifolii for clover and R. loti for trefoil just prior to seeding will ensure nitrogen fixation occurs in the established forage stand.
  • Often, rest alone can be an simple and effective tool to rejuvenate stands.
