Article Summary: Mixing ryegrass with clover and other companion plants can boost pasture productivity, improve animal health, and reduce input costs. By adding diversity to the sward, farmers can create more resilient, nutritious, and sustainable grazing systems.
Moving Beyond a Monoculture Mindset
While ryegrass pastures can be highly productive, a pure stand is not always the most resilient or efficient choice. By incorporating other species into your sward particularly legumes like white clover you can improve both pasture performance and long-term sustainability.
A mixed pasture works much like a well-balanced team. Ryegrass brings strong growth and high palatability, while clover offers nitrogen-fixing benefits and extra protein. Together, they create a sward that supports animal health, reduces input costs, and maintains productivity even when conditions turn challenging.
Why Ryegrass and Clover are a Classic Pairing
Perennial ryegrass and white clover form the backbone of many productive dairy and livestock pastures. This combination is popular for good reason:
-
Natural Nitrogen Supply – Clover, as a legume, has the ability to fix nitrogen from the air through its root nodules. This nitrogen becomes available to surrounding grasses, reducing the need for synthetic nitrogen fertilisers. In some systems, farmers can cut fertiliser use dramatically, saving money and reducing environmental impact.
-
High-Quality Feed – White clover is highly digestible and richer in protein compared with ryegrass alone. Animals grazing clover-rich pastures often eat more, leading to higher milk yields or better liveweight gains.
-
Seasonal Benefits – Clover often thrives in the warmer mid-summer months when ryegrass growth may slow, helping to maintain pasture quality through the season.
Farmers frequently report noticeable improvements after adding clover to their pastures. Some find they need less supplementary feed, while others see pastures stay greener for longer during dry spells.
Benefits for Animal and Pasture Health
Mixed pastures can enhance both livestock health and the resilience of the pasture itself.
-
Animal Health – Clover can help reduce the risk of grass tetany, particularly in spring. Its higher magnesium content supports healthier calving seasons and fewer metabolic issues.
-
Extended Productivity – If ryegrass growth slows during a dry or hot period, clover or other companion plants can continue producing, ensuring a steadier feed supply.
-
Soil Improvement – The different root structures of ryegrass, clover, and herbs help improve soil aeration and organic matter, while also reducing compaction.
Adding Other Species for Diversity
While ryegrass and clover are a tried-and-true mix, other species can further improve pasture resilience.
-
Herbs such as Chicory and Plantain – These deep-rooted plants can draw minerals from deeper soil layers, provide drought resistance, and in the case of chicory, offer natural anthelmintic benefits for sheep.
-
Additional Grasses – Tall fescue or festulolium (a fescue-ryegrass hybrid) can extend the growing season and perform better in heat.
-
Annual Forage Blends – For winter grazing, annual ryegrass can be sown with oats or rye, or combined with brassicas like turnips, to create a diverse feed source. These mixtures can provide quick growth, variety, and strong feed yields.
The key advantage of diversity is stability if one species struggles under certain conditions, another can fill the gap.
Establishing and Managing a Ryegrass-Clover Mix
Success with mixed swards comes down to good establishment and careful management.
-
Seeding Rates – For new pastures, include about 1–2 kg/ha of white clover in the seed mix so it establishes alongside the ryegrass.
-
Overseeding – Clover can be introduced into existing ryegrass pastures by oversowing after renovation or through frost-seeding in suitable climates.
-
Grazing Management – Rotational grazing supports clover persistence by allowing plants to rest and recover. Avoid very low grazing residuals to let light reach clover growing points.
-
Fertiliser Use – Reduce synthetic nitrogen when clover is present; excessive nitrogen favours grass growth over clover and reduces the legume’s nitrogen-fixing activity.
-
Weed Control – Minimise broadleaf herbicide use where possible, as these products will also damage clover.
It is common for clover content to be low in spring and then increase in summer if managed well this is a natural seasonal pattern.
The Long-Term Payoff
Mixed ryegrass-clover pastures offer a range of practical benefits:
-
Higher Forage Yield and Quality – Over a year, mixed pastures tend to produce more high-quality feed, supporting better animal performance.
-
Lower Fertiliser Costs – Even a small increase in clover content can supply significant amounts of nitrogen to the pasture.
-
Improved Soil Health – Diverse root systems improve soil structure, water infiltration, and organic matter content.
-
Weed Suppression – A dense, diverse sward leaves fewer opportunities for weeds to establish.
By replacing part of a monoculture ryegrass sward with clover and other species, farmers can build a more productive, sustainable, and resilient grazing system.
Until we meet again, Happy Grazing!
