Pasture Blends

Most forage seed companies offer a pasture blend. Some customize their blend to the customer’s situation, but others use a least-cost formulation to produce a more attractively priced blend. Ideally, the blend should contain grasses and legumes that grow well together, are well-adapted to the environment and soil type they will be seeded in, will tolerate grazing, and produce good animal performance. Seed companies often don’t have all the information they need to formulate these ideal blends. As one example, forage breeding plots are typically far too small to graze, so forage yield is evaluated using a plot harvester. This means that forage varieties are being selected for their ability to produce and recover from mechanical harvesting rather than grazing. Forage improvement programs that integrate the breeding, agronomics, and grazing management research programs to gather the data needed to develop effective pasture blends take a long time and are very costly.

Forage stand mixtures



Establishing new pastures can be expensive and producers often prioritize stand life over yield. Seeding complex mixtures of grasses and legumes that maintain highly diverse botanical composition in pastures can contribute to increased persistence, yield stability and improved productivity. Yields benefit from including highly productive as well as drought-tolerant species. While some species will not persist beyond the first three or four years, other species in the mix can fill in the gap to maintain overall yields, to a degree.

Schellenberg (2013)1 assessed the productivity and crude protein content of forage stands to determine if species show complementarity in Swift Current, Saskatchewan. The fast growing and highly competitive species dominated biomass production in the early establishment phase.  Including less productive species in the forage sward had minimal impact on pasture productivity or nutritional value under good growing conditions. However, less productive species should be included in pasture mixes when they bring beneficial traits (i.e. increasing nitrogen availability, drought resistance) to the forage stand that provide ‘insurance’ for less optimal years.

Determining optimal forage species mixtures

Forages are a major feed component for the cow-calf and backgrounding sectors of the beef industry. Appropriately managed pasture with a significant legume component is inherently one of the most sustainable feed sources. Because forage species have different yield potential and nutritional quality, the mixtures of forage species in pastures can influence the productivity of the grazing cattle.
