Irwin Hunter & Co has three standout pasture seed blends tailored to WA farmers: MaxiMix, SouWest, and Self Regeneration Mix.

Each is designed with productivity, palatability and long-term value, offering solutions for seasonal productivity and/or future pasture persistence.

MaxiMix

MaxiMix is a versatile, all-around performer that delivers high production and exceptional nutritional value across a broad range of soil types – combining short to medium maturity Diploid and Tetraploid annual ryegrasses, oats and carefully selected aerial-seeded clovers, and a white seeded sub clover, which guards against seasonal variability – early or late starts and early or late finishes.

The mix offers productive and excellent feed quality throughout the growing season, and boosts nitrogen fixation and soil health for the long term.

It is suited for grazing, silage or hay.

When allowed to set seed in spring, MaxiMix will regenerate, with its inclusion of hard-seeded clovers that can protect against a false break, giving farmers a sustainable pasture in the following years.

With a 25–35kg/ha sowing rate and ideal for areas with 450mm+ rainfall and pH 5+, it offers a balance of production and resilience for year-on-year returns.

SouWest

SouWest, WA's proven and trusted pasture mix, which, even with seasonal variability, offers productivity and diversity across a wide range of farming systems.

Its blend of productive annual and perennial ryegrasses, with an array of hard-working clovers including Arrowleaf, Crimson, Persian, Balansa and sub clovers, this mix ensures seasonal balance and sustained growth.

SouWest thrives on good grazing practices and can also be managed to regenerate year after year.

This mix sets the benchmark for mixes in WA, providing versatility for grazing, haylage, silage, hay, or regenerative options.

Recommended sowing rates are 15-25 kg/ha.

Self Regeneration Mix

Self Regeneration Mix is a forward-thinking solution for those needing early-flowering ryegrass and clover pastures that also guard against Annual Ryegrass Toxicity (ARGT).

Featuring Safeguard ryegrass, this blend, with a sustained regenerative management program, prevents toxic bacterial colonisation, making it safe for grazing into spring and summer.

Combined with sub, Rose, and Balansa clovers, the mix can lift winter dry matter yields by up to 50 per cent against unimproved pastures, supporting feed demand during crucial low-growth months and providing a sustainable option for future regeneration, if allowed to come to seed in spring.

Whether you're chasing early-season bulk, safer and productive, or a well-rounded all-rounder pasture, Irwin Hunter & Co has a mix to match your pasture goals — delivering productivity now and persistence into the future.
