Like clockwork, Riverview applies manure, fulfilling nutrient needs of surrounding farms

As the sun dipped below the horizon, casting a warm glow over the fields of Murdock, Minnesota, David Yost stood by a massive tank filled with liquid manure. The unmistakable scent wafted through the air, but for Yost and his team at Riverview, this was not just a byproduct of dairy farming; it was a vital resource. For the surrounding farms, the nutrient-rich liquid would soon nourish the soil, ensuring the cycle of growth continued. From late August to late October, this process unfolds like clockwork, with Riverview’s Louriston Dairy moving between 80 million to 85 million gallons of manure across neighboring fields.

What Happened

The meticulous operation of moving manure from the dairy to the fields is a testament to modern agricultural practices. Yost, the regional forage and manure manager at Louriston Dairy, emphasizes the importance of regulation and coordination in this process. "This isn’t something where we can just go do whatever we want," he stated. The perception that manure application is a chaotic endeavor is far from the truth; it involves careful planning and adherence to environmental standards set by the Minnesota Pollution Control Agency.

Tyler Evink, the feed and manure manager, echoes this sentiment, noting that manure is one of the most regulated fertilizer sources available. "People can trust that it’s being handled in the right way," he said. This trust is essential, as the surrounding farmers rely on Riverview to fulfill their nutrient needs, ensuring that their crops thrive year after year.

In October, during a visit to the site, the application process was in full swing. Fields were being prepared for next year’s corn crop, following a rotation plan that takes into account what was previously grown and what will be planted next. This careful orchestration of crop rotation ensures that the soil remains healthy and productive.

Understanding the Process

The application of manure is not merely a matter of spreading it over fields; it requires a deep understanding of agronomy. Each field has unique nutrient needs based on previous crops and soil conditions. Yost explained that they conduct soil and manure sampling to determine the appropriate application rates. This data is crucial in developing a nutrient management plan that aligns with both agronomic needs and environmental regulations.

The process is further enhanced by technology. Flow meters and GPS rate controllers are employed to monitor and record the amount of manure applied to each field. This information is not only vital for operational efficiency but also for compliance with state regulations. Each year, Riverview must report this data to maintain their feedlot permit, ensuring transparency and accountability in their operations.

Technology in Action

One of the standout features of Riverview’s manure application process is the use of real-time monitoring technology. Cory Ahrens, crew lead for Swift Pumping, showcased an app called Lightspeed, which allows him to track the flow of manure directly from his smartphone. This innovation means that any issues can be addressed immediately, without the need to race across the farm. Ahrens explained, "The flow rate is shown in real time, by the second," ensuring that they apply the correct amount of manure to each acre.

In addition to monitoring the flow, Riverview also conducts regular manure sampling to ensure quality. Ahrens noted that they take one to two samples per shift to send to a third-party lab. This rigorous testing helps maintain the integrity of the nutrient application process, ensuring that the right balance of nitrogen, phosphorus, and potassium (NPK) is achieved.

Community Impact

The relationship between Riverview and the surrounding farmers is symbiotic. Riverview does not own the fields around Louriston Dairy; instead, they rely on local farmers who are eager to receive the manure. Yost shared, "We have more neighbors who want manure than we have manure to sell." This high demand underscores the value of the nutrient-rich liquid for local agriculture.

Each season, Riverview collaborates with about 12 to 15 farmers for manure handling. These partnerships are built on trust and mutual benefit, as farmers depend on the manure to enhance their soil health and productivity. The careful management of this resource not only supports local farms but also contributes to the sustainability of agricultural practices in the region.

For many local farmers, the relationship with Riverview is more than just a business arrangement; it is a lifeline. Farmers like John Anderson, who has been working with Riverview for over a decade, emphasize how vital the manure is for their yields. "Without this resource, our soil would struggle to provide the nutrients our crops need," Anderson stated. His corn and soybean fields have thrived thanks to the nutrient application, allowing him to maintain a successful farming operation.

As they approach the self-imposed completion date of November 1 for manure application, Riverview has been fortunate this season with drier weather conditions. Ahrens expressed optimism, stating they were well on target to finish on time. This timely application is crucial, as it minimizes the risk of runoff during inclement weather, protecting local waterways and the environment.

Looking Ahead

The future of manure application at Riverview is bright, with ongoing advancements in technology and a commitment to sustainable practices. As the agricultural landscape continues to evolve, the integration of precision farming techniques will play an increasingly important role in nutrient management. Yost and his team are dedicated to staying ahead of the curve, ensuring that they meet both the needs of the crops and the regulatory standards.

Moreover, the collaboration between Riverview and local farmers exemplifies the spirit of community in rural Minnesota. By working together, they not only enhance their own operations but also contribute to the overall health of the agricultural ecosystem. This commitment to responsible farming practices is vital, as it helps secure the future of farming in the region.

As farmers prepare for the next planting season, the lessons learned from this year’s manure application will inform their strategies moving forward. With a focus on sustainability and efficiency, the partnership between Riverview and the local farming community stands as a model for others to follow, demonstrating that with dedication and innovation, agriculture can thrive while respecting the environment. As the agricultural sector faces challenges such as climate change and fluctuating market demands, the adaptability shown by Riverview and its partners may serve as a blueprint for resilience in the farming community.
