Dr Rod Greder | Developing Innovative Tools to Incentivise Sustainable Cattle Ranching

Jul 27, 2022 | Agricultural Science

Small, seemingly minor annoyances can be the final hurdles standing in the way of a good idea. Dr Rod Greder, a rancher and researcher, experienced this first-hand when studying cattle farms. Some best practices for pasture-based cattle production can be time-intensive, deterring many farmers from making the shift. Moreover, we still lack reliable scientific data that can be presented to farmers to demonstrate the economic advantages of pasture-based practices, such as intensive rotational grazing. To incentivise more farmers to make the transition to this more sustainable form of raising cattle, Dr Greder has created simple, cost-effective tools that make managing and monitoring pastures more profitable and sustainable for the rancher.

Pasture-based Animal Production

Pasture-based systems offer a more sustainable way to raise cattle and use land that is not suitable for crop production. On these farms, cattle roam pastures and graze on grass and other plants while depositing manure in the field where it is needed. This can translate to healthier animals, fewer veterinary bills, and more nutritious meat and milk.

Well-managed farms distribute animals across the pasture, spreading their manure more evenly and improving the quality of the grass, which in turn reduces soil erosion and water pollution. Rotational grazing can build rich soils that conserve water and are sustainable for decades of use. These myriad benefits make well-managed pastures more resilient in the face of climate change.

However, the way in which a pasture-based farm is managed dictates whether the system is net beneficial to the environment. To truly adopt best management practices, farmers must make sizable financial and time investments – costs that some farmers cannot absorb.

Dr Greder realised that many of the most common complaints associated with intensive pasture management focus on inefficient practices that could be improved with easy-to-use, simple tools. With the goal of increasing the adoption of pasture-based systems, Dr Greder’s novel tools can make the lives of ranchers easier. His innovative methods also promote and strengthen the most environmentally friendly aspects of pasture-based farms, while providing measurement tools to document quantity and quality benefits of intensive rotational grazing. These tools allow ranchers to test different management practices and gather data to confirm that they are sustainable and cost-effective.

The Pasture Productivity Pail

While working at the University of Minnesota, Dr Greder pioneered a study to create affordable, easy-to-use tools to document how different grazing methods can improve soil health and water quality. Currently, most ranchers use qualitative assessments to evaluate the benefits of grazing systems, which are often inaccurate. With a science-driven tool that provides hard data on the benefits of grazing management, best practices might be more readily adopted by hesitant farmers.

With funding from the United States Department of Agriculture (USDA), Dr Greder began a three-year project. He collaborated with ranchers to create a mobile, easy-to-use tool that measures important soil characteristics, including fertility, temperature and moisture, and above ground forage quantity and quality.

After three years of working with ranchers, Dr Greder and his colleagues created the ‘Pasture Productivity Pail’ – a set of portable tools carried in a bucket, which is used to make informed decisions on pasture management. The Pasture Productivity Pail includes resources that measure important soil characteristics, quantify forage quality and quantity, and provide information for ranchers to identify and manage weeds and optimise thicker plant stands and more beneficial plant mixtures.

‘We identified a set of comprehensive, easy to use tools that a rancher can take to the field and determine the quality and quantity of their pasture forages,’ says Dr Greder. ‘This provides data that they can use to make fact-based decisions on how to choose best management practices that result in improved pasture output, animal productivity, farm profitability and environmental sustainability. This pail also becomes an in-field awareness tool that ranchers can use to educate themselves and staff about all aspects of forage production and optimisation.’

As part of his research, Dr Greder interacted with many ranchers, asking them for insight on what management practices could result in greater productivity. Many ranchers and grazing experts have shown that more frequently moving cattle stimulated soil health and spread manure in more sustainable ways, improving forage productivity. However, anywhere that cattle go, critical equipment must follow, which can be cumbersome for the rancher. This common complaint inspired Dr Greder’s next innovation – a way to transport necessary equipment across a pasture more easily.

Rotational grazing describes the practice of moving cattle to different portions of the pasture, allowing each area of a farm to have rest periods without grazing. Well-managed rotational grazing allows both the roots and shoots of the forage to recover and grow more vigorously.

However, the benefits of rotational grazing are not free. Ranchers must consider the expenses of rotational grazing, including more fencing, more labour and more intricate watering systems. Although these trade-offs are generally acceptable to ranchers, Dr Greder realised that few resources discuss the physical hassle of moving supplies across the pasture.

When thinking about his own farm, Dr Greder realised that he often reduces the frequency of cattle rotations to save the hassle of moving equipment. This revealed yet another weak point in pasture-based management that could be eliminated with creative, innovative tools.

In another project funded by the USDA, Dr Greder surveyed ranchers to design a mobile unit that can be easily transported across a pasture with standard farm equipment, such as a tractor or truck. The mobile cart contains critical equipment that farmers need to move along with their cattle, such as mineral stations, water troughs, fly control, fencing supplies and optionally, shade protection. After several iterations of prototypes that incorporated rancher feedback, Dr Greder is currently in the final stages of preparing his mobile cart for commercial sale.

More Pasture-Based Operations

Dr Greder has leveraged his decades of experience in agricultural research and a lifetime of working on farms to identify and address critical problems that are unique to pasture-based systems. The Pasture Productivity Pail and Mobile Grazing Cart are easy-to-use tools that will immediately make life easier for ranchers who are trying to manage their pastures in more sustainable and productive ways. By removing these small yet persistent obstacles and by providing easy-to-use tools, Dr Greder has made pasture-based cattle ranching a more attractive option. When adopted at a large scale, his innovations will help to make cattle production more sustainable, allowing farmers to stay in businesses while also protecting the environment for future generations.

Dr Jon Neill | The Impact of Trade Deficits in America

Former President Donald Trump promised to bring jobs back to the U.S., arguing that the trade deficit was responsible for slow economic growth and costing the economy jobs. While the Trump administration popularised the issue, historically, the broad impact of trade deficits has been contentious. Dr Jon Neill is a Professor of Economics at Western Michigan University. His computational modelling has shown that U.S. residents would experience a slight loss if consumer goods currently being imported from countries like China, were produced domestically instead. His calculations question whether the net benefit from trade with low-wage countries is warranted, given the distributional impact of that trade.
