Balansa Clover
Trifolium michelianum

BOLTA (Trifolium michelianum) is an annual temperate pasture legume that grows during the autumn, winter, and spring seasons.

A late maturing hard seeded Annual Clover, BOLTA is well suited to medium to high rainfall environments, demonstrating semi-erect growth when grown in a mixed sward situation, however, will remain prostate if grown as a pure sward or grazed.

Bolta can provide excellent herbage production (particularly in spring conditions) and was selected for its superior late season production when compared to Paradana. Enhanced establishment is possible due to the seed size of Bolta being 15-20% larger than Paradana, assisting improved seedling vigour.

Bolta is an exceptional pasture variety suited to heavy grazing, is highly digestible (14-18% crude protein), and can be used on its own or in a pasture mixture with companion species such as sub clovers, grasses or lucerne, as well as providing the added benefit as a disease break whilst also fixing nitrogen.

Bolta Balansa Clover, Frances South Australia

Nathan Smith is at Frances, SA in a Bolta Balansa seed crop. The crop is a regenerated paddock that was taken for seed last year. It started germination from March and had a broad leaf spray applied. It has really good plant density. As the sun starts to warm up more, it will be in a good position to lock up for seed followed by grazing. Annual Clover
