Balansa Clover
Trifolium michelianum

Frontier is an annual temperate pasture legume that grows during the autumn, winter and vigorously during spring.

Frontier is an early maturing hard seeded annual clover, that is well suited for low to medium rainfall zones. It demonstrates semi-erect growth when grown in a mixed sward, but the plant will remain prostrate if grown as a pure sward or grazed. Leaf size, shape and markings vary significantly with some having strong leaf marks ranging in colour from white to silver, pink or green.

Frontier can provide excellent early herbage production in medium rainfall zones. It was selected for its early flowering attribute and increased forage production. Frontier has excellent seed yielding ability that ensures good regeneration and pasture density suited to heavy grazing. It is highly digestible (14-18% crude protein) and can be used on its own or in pasture blends that may consist of persian clover, sub clover, grasses or lucerne. Frontier provides added benefits as a disease break while fixing nitrogen which is available in the soil for the subsequent crops.

Frontier Balansa Clover, Keith South Australia

Here’s a production inspection of an early flowering Balansa crop called Frontier. It’s a second year regeneration paddock. The paddock is looking good for crop hygiene. In alkaline country, conical snails can be an issue but they’ve been baited to reduce damage to the crop in seedling stage. Frontier is very hard seeded and a prolific seeder. In long term pasture blends where farmers are looking for continual regeneration, Frontier Balansa fills that on farm requirement. Annual Clover
