Kochia is no stranger to Saskatchewan fields. From field edges to saline patches, this drought-tolerant and herbicide-resistant weed continues to challenge producers across the province. As a result, many growers are reevaluating how to approach managing kochia beyond traditional solutions. 

One strategy that seems to be gaining popularity is converting marginal cropland to perennial forage, turning problem acres into productive areas for grazing or hay. For farms that are consistently underperforming and attracting kochia, this approach can reduce input costs, limit the spread of kochia, improve soil health, and provide new income streams through hay or custom grazing. 

Kochia thrives in marginal cropland due to its ability to adapt to harsh growing conditions. It tolerates a wide range of soils, including saline, sandy, and low-organic matter types which are commonly found in marginal croplands. It is drought tolerant due to its deep taproots and it also is one of the earliest weeds to germinate in the spring, giving it a head start over other crops. Once established, its rapid growth and prolific seed production makes it difficult to manage. Kochia is often resistant to several herbicide groups including Groups 2, 4, and 9, limiting chemical control options. 

Converting marginal cropland to perennial forage crowds out kochia. Once perennial forage species are established, they shade the soil surface and restrict sunlight kochia needs to grow. These systems also stabilize soil moisture levels, reducing the dry conditions kochia prefers. Reduced reliance on herbicide applications minimizes soil disturbance, which in turn limits kochia establishment. Adding livestock provides another level of control as they consume young kochia plants before they mature. 

Beyond weed suppression, perennial forage systems offer more benefits. Once established, forage stands help stabilize the soil structure, improving moisture retention and reducing runoff. Input costs can be minimized because of the reduced reliance on herbicides. There’s also the benefit of versatility. Depending on the species chosen and management goals, they can be used for hay, rotational grazing, or as buffer zones. 

Converting marginal cropland to perennial forage involves planning and understanding of the site conditions. Working with an agrologist or agronomist can help identify forage species that are well suited to the land and long-term goals. Having a good species mix increases the likelihood of strong establishment and long-term success. Managing Kochia in Saskatchewan isn’t just about spraying- it’s about adapting land use where it makes sense. For marginal acres that consistently underperform, perennial forage offers a practical, low-input alternative that supports agronomic and ecological function while also contributing to long-term economic value.
