Mix components

Formulation 2025

Component
Cowpeas
Fast growing annual legume known for its heat and drought tolerance, providing added nitrogen fixation. A very versatile, high-quality summer forage for grazing, hay or silage.
Millet
Early summer feed. Quick to establish, high yielding leafy plant producing high quality grazing with good regrowth. A great fibre provider.
Chicory
A drought tolerant perennial herb with a very deep tap root that has been known to break mild hard pans and draw moisture from deep within the soil profile. This taproot allows it to hang on well and produce quality forage with high nutrient and energy levels. Tolerant of grazing pressure with parasite inhibiting properties, and the flowers attract beneficial insects.
A robust root system that assists with drawing up nutrients, erosion control and mycorrhizal growth in the soil. Strong tall stalks offer support for companion species, and they attract numerous beneficial insects.
Large leaf area and rapid growth provide good weed suppression and reduced surface compaction. Versatile and suitable for a wide range of soil fertility and environmental conditions, stock classes and sowing times. Good frost tolerance and excellent regrowth potential, and may extend grazing from early summer to late winter.
Early summer feed and an excellent cover crop to assist in breaking a compaction layer in the soil. Being deeply rooted it relocates nutrients further down the soil profile and brings them back to the surface when it decomposes.
Widely grown as a cover crop, with rapid and dense growth choking out weeds. Often grown to attract beneficial insects.

*Occasionally some varieties in our mix will be replaced with a like-for-like variety where the original is not available or not easily accessible. Varieties in the mix will be specified on the bag label.

About this seed blend

Cover Crop Plus Summer Mix is a unique blend of 7 species which combines all the benefits of cover cropping, with species that provide high levels of biomass, nitrogen fixing legumes, soil improvers that improve soil structure and health, and species that attract beneficial insects. It is suited to a wide range of soil types and conditions, and serves as a valuable forage for livestock in mixed farming systems.

Cover crops provide protection to what may be bare soil for a large portion of the year, covering it like a protective blanket of biomass that ensures water infiltration and retention. By mulching the cover crop, further benefits are achieved by maintaining the cover and adding organic matter and carbon to the soil once decomposed.

Planting a selection of different species creates the biodiversity that helps promote the health of your soil, with a long list of benefits that include soil health, erosion control, weed suppression, nutrient management, drought resilience, salinity management, pest and disease management and carbon sequestration in the soil.

Biological BioNPK S coated. ECOCERT approved.

Planting & grazing notes

Optimal sowing time is spring. Decide the location based on the agricultural and environmental benefits you want to achieve, and have a soil test done. Ideally spray out any existing pasture or persistent weeds before planting and prepare an optimal seed bed, applying lime or gypsum if required. Ensure paddocks are clean of weeds and competitive grasses and you have no history of problem weeds. Ensure adequate soil moisture with the possibility of follow up rain, and choose a sowing method that gives good seed to soil contact. Increased sowing rates will increase your interplant competition and weed competition, assisting in reducing the weed burden and the requirement for early herbicide applications. Once established, ensure plants are not prone to pulling, then graze, mulch or leave to stand. If grazing, rotate or strip graze to give the pasture time to recover and regrow.

FAQs

What can I sow over summer to stop my bare paddock blowing away?

We recommend our Cover Crop Plus Summer Mix. It blends grains, broadleaves and legumes to put a blanket of biomass over the soil, protecting against erosion and helping water infiltration. It suits light sand to heavy soils with pH 5.0+ and 350mm+ rainfall, and is sown in spring.

What summer cover crop mix builds soil health in WA farming systems?

Our Cover Crop Plus Summer Mix combines species for biomass, nitrogen-fixing legumes, soil improvers and plants that attract beneficial insects. It includes cowpeas, millet, chicory, sunflowers, Winfred Forage Brassica, tillage radish and buckwheat, and is coated with biological BioNPK Powder S and ECOCERT approved. It suits light sand to heavy soils with pH 5.0+ in 350mm+ rainfall areas.

When do I sow a summer cover crop, and at what rate?

We recommend sowing our Cover Crop Plus Summer Mix in spring at 15 to 20 kg/ha. It suits 350mm+ rainfall areas and light sand to heavy soils with pH 5.0+. Sow into adequate soil moisture with the possibility of follow-up rain, using a method that gives good seed-to-soil contact.

Can I graze a summer cover crop, and how should I manage it?

Yes. Our Cover Crop Plus Summer Mix can be grazed, mulched or left to stand once established, when plants are not prone to pulling. If grazing, we recommend rotational or strip grazing so the pasture can recover and regrow. Because the mix includes Winfred Forage Brassica, introduce stock gradually and monitor animal health.

What cover crop helps break up compacted soil over summer?

Our Cover Crop Plus Summer Mix includes tillage radish, a deep-rooted cover crop that helps break a compaction layer, and chicory, whose very deep tap root is known to break mild hard pans. The mix also adds biomass and nitrogen from legumes, and suits light sand to heavy soils in 350mm+ rainfall areas.

Does sowing cover crops count toward carbon credits in Australia?

Cover cropping is one of the practices that can support soil carbon projects earning Australian Carbon Credit Units (ACCUs), subject to the scheme rules. Our Cover Crop Plus Summer Mix builds soil health, covering the soil with a protective blanket of biomass, and mulching it adds organic matter and carbon to the soil once decomposed. We recommend checking eligibility with a carbon adviser.

I want a summer crop that brings in bees and beneficial insects to my farm. What should I sow?

We recommend our Cover Crop Plus Summer Mix, which includes flowering species such as sunflowers and buckwheat that attract beneficial insects, along with legumes and brassicas. The diversity supports biodiversity and pest suppression. It flowers over summer and suits 350mm+ rainfall.

What species are in Cover Crop Plus Summer?

Cover Crop Plus Summer Mix currently contains seven species: cowpeas, millet, chicory, sunflowers, Winfred Forage Brassica, tillage radish and buckwheat. Together they provide biomass, nitrogen fixation, deep roots and flowers for beneficial insects. We update our mixes from time to time, so check your bag label for the exact varieties.

Cover Crop Plus Summer vs Cover Crop Plus Winter, which do I need?

Choose by season. Cover Crop Plus Summer Mix is sown in spring and grows through the warm months with species like cowpeas, millet and sunflowers, while Cover Crop Plus Winter Mix is sown in autumn with cool-season species such as oats, ryegrass, vetch, peas and clovers. Both suit light sand to heavy soils with pH 5.0+ in 350mm+ rainfall areas.

Is Cover Crop Plus Summer drought tolerant?

Yes, Cover Crop Plus Summer Mix is built on heat and drought tolerant summer species, including cowpeas and the deep-rooted chicory and tillage radish. It still needs 350mm+ rainfall or stored soil moisture to establish and grow well, so sow in spring into adequate soil moisture with the possibility of follow-up rain.
