OSU economist says taxing farmers would resolve phosphorus issue

Scales and money

WOOSTER, Ohio — Farmers, researchers, private companies and state and federal conservation groups have been actively involved in the effort to reduce nutrient runoff in Ohio for the past several years.

Their goal is to keep Ohio’s lakes and streams clean and prevent the growth of harmful algae. And, they’ve been vocal about wanting to do as much on their own and without regulation as possible.

But an economist with Ohio State University says those efforts haven’t been enough. Instead, he suggests the most cost-effective solution is a tax on phsophorus — which he predicts would reduce the amount farmers apply, and thereby reduce the amount that runs off their fields.

Brent Sohngen, an environmental economics professor in the College of Food, Agricultural and Environmental Sciences and leader of OSU’s Environmental Policy Initiative, held a webinar Sept. 30 in which he outlined the benefits of taxing farmers.

He drew connections between the cost of fertilizer and the amount farmers use, arguing that when prices are higher, farmers adjust and use less.

Lowering concentration

As an example, he said a 135 percent tax on phosphorus would be enough to decrease the concentration by about 40 percent, the same amount state leaders have generally called for, when talking about reductions in runoff.

Sohngen said there has been “an enormous investment from the conservation community,” costing society and taxpayers about $11 to $16 per acre annually.

“We don’t seem to be seeing much of a payoff from that.”

The ag economist said dissolved phosphorus levels are still too high in our water, and suggested that the issue is directly related to the amount being used. When the price goes up, farmers use less.

By his figures, a 10 percent increase in price reduces “emissions of soluble phosphorus by 3 to 4 percent.”

Different perspectives

Kevin King, a research agricultural engineer with the U.S. Department of Agriculture, was listed as a co-author of Sohngen’s report.

However, when Farm and Dairy called him for a supplemental comment, he said he was unfamiliar with the report and would be asking that his name be removed.

King said he had spoken years ago with Sohngen about the potential of price impacts on phosphorus use, but that he didn’t agree with the conclusions in the report. King said a tax could be an alternative solution, but not one that he would prioritize.

“I’m out here trying to look at the 4-R approach and other things,” he said. “I’m not going to deny that a tax or some other thing isn’t an alternative, but I don’t think that’s the way we want to go.”

Sohngen argued his plan would shift the cost burden of conservation practices from the public to the farmer.

He estimated the effect of a tax, at 135 percent, would cost farmers in the northwestern Ohio watersheds about $27.8 million, or about $6 more per acre.

What about food prices?

There was concern during his presentation, however, that such a shift would also cause a shift to the consumer in the form of higher food prices. For one thing, phosphorus is an essential nutrient for plants like corn to grow, and yield is directly related.

Sohngen argued farmers have reduced phosphorus application in the past without any yield issues, partly because some fields already have excessive amounts in reserve.

As for long term, he said it was his “heartfelt” belief that seed companies, with all their innovation, “would have very little struggle compensating for that over time.”

Profit crunch

Another issue is the cost to production. Farmers have to subtract their input costs from the price they receive for their crop. A new tax of $6 per acre, along with the potential for reduced yield, could challenge an already tight profit margin.

Larry Antosch, Ohio Farm Bureau senior environmental policy director, was among several dozen who listened to the webinar.

Antosch is still reviewing Sohngen’s figures, but he said Farm Bureau does not currently have a policy on taxing phosphorus.

Instead, the organization is “putting our dollars and our efforts to keep on supporting the field research, and helping farmers become (state) certified,” he said.

Antosch was referring to the Ohio fertilizer law, which requires farmers to be state certified by the fall of 2017 if they intend to apply fertilizer to more than 50 acres. The Farm Bureau pledged $1 million to help farmers become certified, and adopt nutrient management plans on their farm.

Apples to apples

Antosch said it’s important to keep in mind that a reduction in the amount of phosphorus applied won’t always result in an equal reduction in the amount leaving the field. And, even small amounts of fertilizer, if not properly managed, can do as much harm, he said.

“A 40 percent reduction in what’s being applied may not be result in the 40 percent reduction in what’s being transported (from the field),” he said.

One area where Antosch seemed to agree with Sohngen was with higher volumes of water and larger precipitation events.

Sohngen suggested that more water is moving through the Maumee watershed, which impacts how much phosphorus is carried from farmers fields.

Antosch prefers to call it “climate weirding,” but whatever you call it, scientists in Ohio are confirming it’s real.

Own path

But Sohngen arguably has some unique views, not only with his proposal to tax the issue, but also his views on conservation agriculture.

He doesn’t see an association between water quality and conservation tillage practices, including no-till, which farmers have been encouraged to adopt for decades as a way of reducing soil erosion and improving water and soil quality — often at the advice and research of other Ohio State faculty.

“When we look at the data, we can’t detect any effect on water quality from the money spent on encouraging farmers to adopt conservation and no-till practices,” he said in an OSU news release. “But we do see an effect when phosphorus prices are higher.”

Sohngen is a graduate of Yale University and has studied the economics of conservation programs and pollution from farmland since he started his career at Ohio State in 1996.

He also led research on cap and trade legislation during President Obama’s first term. The policy was criticized by many farmers as “cap and tax,” and something that would “cap” the nation’s future, and ultimately failed before Congress.

  1. I don’t see anything about the zebra mussels in this?? Blue green algae was licked back in the early 90’s, by the lake clean ups before then. The phosphorous at that time lead to growth of beneficial species and fish thrived. The alewife fish feeds on plankton not blue green algae and its populations are declining as well as the salmon that feed on them in the upper lakes. Then the mussels invaded and have an overwhelming diet based on beneficial algae and plankton. The blue green algae are simply filling in a natural vacuum caused by the excessive feeding by the mussels. The approach need is to make an assault on the mussels, which will be difficult and likely of a genetic nature. Attacking farmers that are already willing to work on things from their end (which is likely not a cause anyway) is a political and government power grab as well as a drain on the economy and a detriment to society in the long run. The reduction in phosphorous in cleaning agents has resulted in too little for water treatment plants to work and they have to add it so the bacteria in their systems can work. Pretty much every focus on issues is misplaced because of political priorities. Besides that they don’t even measure all the nutrient pollution from these waste treatment plants and have overflow from rain issues that cause more problems. Instead of 85% efficiency they are estimated to be only 40% efficient. But these are government entities so their is little political hay to be made in a focus on them, Farmers make a much better target for controlling and taxing for no good reason except political power over them, as they tend to be of independent nature. We can’t have that in today’s overwhelming desire to control everyone’s activity to the maximum. How about government focusing on the real causes? Not just what they can gain power from.

  2. Tax=the power to Destroy.

    This is a new “War on Farmers.”

    When this OSU tax-crazy economist removes himself from the rarefied atmosphere of the faculty lounge where he undoubtedly cooked this up and gets himself out in Ohio’s farmland and:

    Gets up at the crack of dawn, checks his machinery daily for wear/tear, does essential planned maintenance, greases the zircs up, checks oils levels, fuels up, drives to the fields, works his tail off all day (no union-mandated breaks), plows, plants, fertilizes, applies pesticides and fungicides, prays for rain, sometimes prays for less rain, harvests, stores and sells his crop (hopefully at a profit, sometimes not), then I will listen to “Mr. Economist.”

    P.S.
    When Mr. Farmer actually does make a profit and sends a portion downstream to OH Tax Dept., Mr. Farmer’s taxes are paying the guaranteed salary and benefits (even a pension) for the OSU Economist, who is out to drive Mr. Farmer bankrupt and out of business!

    Talk about putting your own neck in a noose to kill yourself off!

    Let me quote you the Sage of Baltimore:

    ““The State has taken on a vast mass of new duties and responsibilities; it has spread out its powers until they penetrate to every act of the citizen, however secret; it has begun to throw around its operations the high dignity and impeccability of a State religion; its agents become a separate and superior caste, with authority to bind and loose, and their thumbs in every pot. But it still remains, as it was in the beginning, the common enemy of all well-disposed, industrious and decent men.”
