MADISON, Wis. – Dairy farms generate massive amounts of data every day – too much for a farmer to analyze alone.
But a new app being developed at the UW-Madison Department of Dairy Sciences called Virtual Dairy Farm Brain aims to collate all that data in real time to help the farmer make better decisions.
The development team includes dairy scientists, agricultural economists and computer scientists, and is led by assistant professor Victor Cabrera. He says farmers use modern systems that each separately generate tons of information.
"Farmers are inundated with information that many times is not being used effectively, and so we said 'What can we do to help in this situation?’” Cabrera relates. “’How can we take advantage of this large amount of information that's very valuable, that they are not taking full advantage of?'"
Cabrera's group right now is streaming data on about 4,000 cows in three Wisconsin herds.
The researchers believe the methodology they're developing will apply to any farm. They hope to have the Virtual Dairy Farm Brain app in on-farm tests before the end of the year.
Today's dairy farmer has daily reports on feed efficiency – pounds of milk produced per pound of feed consumed, written notes on tanker weight when the milk is transported, reports texted from milk buyers, and many other data sources. Cabrera says it's too much data for one person to digest.
"They are not able to grasp it all in their head, and so many times they do these decisions on silos – on a specific thing – trusting and hoping that it's not going to affect the rest, but indeed it does affect all the rest of the systems," he points out.
Cabrera says the final step in developing the Virtual Dairy Farm Brain will be to apply what researchers have learned to create intuitive cloud-based, decision-support tools for the app to allow farmers to use real-time data from their farms to make smart management decisions.

A farm group is helping Iowa agriculture producers find ways to reduce the amount of nitrogen they use on their crops.
Excess nitrates can wind up in ground and surface water, and cause health problems.
Practical Farmers of Iowa is encouraging farmers to find just the right amount of nitrogen they need for their crops - while avoiding applying too much, which the group says is common.
PFI's Field Crops Viability Coordinator - Chelsea Ferrie - said thanks to federal grants and private funding, the group will pay farmers up to $35 for every acre that has a lower than normal yield if they didn't apply enough nitrogen.
"No cost to the farmer, either," said Ferrie. "We're trying to help incentivize them. This is something that farmers want to do - I mean, they want to be good stewards of the land - but also, that they need to have a profitable farm."
The application period for the program is open through the end of April.
To help them reach the right nitrogen balance, Ferrie said PFI will help farmers on the front end of the process, too - so they aren't left guessing how much to apply.
"Talk through what your typical fertilizer plan is, and what your reduction plan would be," said Ferrie. "Then you would implement this year, going into the spring and into the season."
Farmers have relied on nitrogen-based fertilizers for generations - but when applied in excess, nitrates run off into ground and surface water, posing health concerns for animals and people.

Pesticides are still common in agriculture. Organic producers who avoid them have seen ups and downs in pushing for stronger regulations, and they point to a South Dakota example of the harm associated with widespread use among neighboring farms.
At the heart of the regulatory fight is the application of the weed-killing pesticide dicamba, and how it can drift from one farm to another. Last month, a federal court blocked "over the top" spraying of dicamba products, but the EPA followed with an order to allow the spraying of existing supplies.
Glenn Pulse, co-owner of an organic farm in Vermillion, said a 2017 drift incident had a big impact on his operation.
"Our entire farm was covered. We lost a lot of livestock, and thousands of bees were killed," he explained.
It also resulted in health concerns for his family, having to regain his organic farmer certification, and a legal battle over restitution. Groups such as the National Family Farm Coalition have been fighting what they call the deregulation of these chemicals, arguing the drift and runoff effect has damaged millions of crops.
Dicamba-manufacturing companies deny responsibility, instead blaming farmers who apply it for not following guidelines.
The EPA has said there were already millions of gallons of dicamba in circulation prior to the court's ruling, prompting the agency's order. Pulse feels there are farmers who are careful in spraying chemicals, but he wants stronger enforcement against those he describes as "loose cannons."
"The guys that are not following the labels and they're spraying in weather conditions that are not favorable, that is where, I would say, 90% of the problems are happening with drift incidents," Pulse said.
His calls for better responses to these incidents coincide with policy demands to heavily restrict dicamba products. Meanwhile, Rep. Dusty Johnson, D-South Dakota, is the main sponsor of a bill supporters say would assure uniformity in national pesticide labeling under federal law. But opponents argue it would limit longstanding state and local pesticide safety rules.

Montana farmers have testified before a panel of state lawmakers asking them to protect agricultural data that is collected by precision farming technology - and stored electronically, "in the cloud."
They're looking for changes in how that information is accessed.
At a recent state Economic Affairs Committee meeting, Montana Farmer's Union President Walter Schweitzer said with the increased use of precision ag tools and a huge uptick in data collected and stored remotely, farmers' information needs greater protections.
"We read every day that there's data being hacked," said Schweitzer. "The military has gotten hacked. Banks have been hacked. Hospitals are being hacked."
Schweitzer argued that hackers could use the information to affect prices or direct-market products to farmers based on the information they collect about crops and ag operations.
He said based on farmers' input, the Economic Affairs Committee will work with lawmakers to consider changes during next year's legislative session.
Rather than tighten access, Schweitzer said he thinks ag data should be made more transparent and publicly available.
He explained that this would help avoid the potential for market manipulation by commodities brokers or large countries, such as China, that purchase the crops.
"Let's say the wheat crop, during harvest, it looks like it's going to be lower yields than average or anticipated," said Schweitzer. "So then, China would come in, purchase all the wheat they needed before the USDA announces that, and the price goes up."
Schweitzer said 10% of a farmer's data, which is uploaded in real time during harvest and stored in the cloud, is all it takes for hackers to know a producer's entire harvest.
