NDSU Researchers Seek Farmer and Rancher Input on Precision Agriculture Data Use

North Dakota State University (NDSU) researchers in the Department of Agribusiness and Applied Economics are seeking input from farmers and ranchers about use of data generated from precision agriculture activities.

“Generating information to improve the use of farm resources and best meet operational objectives is at the center of precision agriculture,” says Cheryl Wachenheim, NDSU Department of Agribusiness and Applied Economics professor. “For example, soil sampling and yield monitor data can be used to prescribe zone application of fertilizers and seeding rates. We have learned a lot about how farmers and ranchers are using the tools of precision agriculture and are now seeking their feedback about control of the data they generate.”

The environment of rich and easily accessible and manageable data from precision agricultural technologies is evolving and new to an industry most familiar with an environment of tangible assets for which property rights are generally explicit. Farmers and ranchers are, for example, able to control access and prevent others from using their land, machinery and equipment, and other tangible assets.

The property rights of data are less clear, and there is no regulatory framework that clearly defines rights to production and farm data. As a result, there are a myriad of uncertainties and concerns regarding the collection, control, sharing and use of the data generated by farm operations.

The data is of value to farmers and ranchers and those who help them make production decisions. However, the data also is of value to a range of other entities including other farms, cooperatives, and those supporting, servicing and investing in agriculture. This potential access by others can be an important consideration for farmers. Once data from precision agricultural operations is released to a company, in the absence of a confidentiality agreement or privacy document, it is available for others to view and use.

“There has been little research conducted on issues concerning precision farming data in terms of farmer’s preferences about data control,” says Wachenheim. “The goal of this research is to understand the viewpoints of those involved in collecting and using the data.”

US Soy: Pig growth is impaired by soybean meal displacement in the diet

Video: US Soy: Pig growth is impaired by soybean meal displacement in the diet

Eric van Heugten, PhD, professor and swine extension specialist at North Carolina State University, recently spoke at the Iowa Swine Day Pre-Conference Symposium, titled Soybean Meal 360°: Expanding our horizons through discoveries and field-proven feeding strategies for improving pork production. The event was sponsored by Iowa State University and U.S. Soy.

Soybean meal offers pig producers a high-value proposition. It’s a high-quality protein source, providing essential and non-essential amino acids to the pig that are highly digestible and palatable. Studies now show that soybean meal provides higher net energy than current National Research Council (NRC) requirements. Plus, soybean meal offers health benefits such as isoflavones and antioxidants as well as benefits with respiratory diseases such as porcine reproductive and respiratory syndrome (PRRS).

One of several ingredients that compete with the inclusion of soybean meal in pig diets is dried distillers grains with solubles (DDGS).

“With DDGS, we typically see more variable responses because of the quality differences depending on which plant it comes from,” said Dr. van Heugten. “At very high levels, we often see a reduction in performance especially with feed intake which can have negative consequences on pig performance, especially in the summer months when feed intake is already low and gaining weight is at a premium to get them to market.”

Over the last few decades, the industry has also seen the increased inclusion of crystalline amino acids in pig diets.

“We started with lysine at about 3 lbs. per ton in the diet, and then we added methionine and threonine to go to 6 to 8 lbs. per ton,” he said. “Now we have tryptophan, isoleucine and valine and can go to 12 to 15 lbs. per ton. All of these, when price competitive, are formulated into the diet and are displacing soybean meal which also removes the potential health benefits that soybean meal provides.”
