This Iowa farmer proves that profit and sustainability go hand in hand

Denny Friest is one of the most progressive and savvy farmers I’ve ever met. Through his participation in the Iowa Soybean Association’s On-Farm Network since 2001, Denny conducted replicated strip trials on his operation to compare different nitrogen application rates and find ways to be more efficient and profitable.

The Iowa legislature saw so much value in this field trial program that it provided funding to reimburse farmers who lost yield in their efforts to improve efficiency. With no risk involved, Denny was able to see “how low he could go” with fertilizer applications before he had an economic loss in production. Read More »

Targeting conservation dollars makes good sense

A University of Michigan study released late last month implies that in order to meet the U.S. and Canadian governments’ 40 percent phosphorous reduction target for Lake Erie by 2025, farmers will need to significantly ramp up their conservation efforts.

Some of the stories covering this study focused on the more drastic measures called for, such as converting thousands of acres of productive cropland to grassland. But I’m optimistic that we can indeed work with farmers to meet this goal by 2025, without having to impact production so drastically – we can do so through targeting.

Targeting refers to directing conservation dollars and practices to places on the landscapes where they’ll be most effective. In Ohio, that means targeting the areas delivering the highest amount of nutrients into Lake Erie.

Here’s the background on targeting, what the research says, and why targeting should be even more finely tuned and amplified at scale in order to accelerate on the ground environmental improvements. Read More »

Lake Erie’s fertilizer problem isn’t over, but we’re working on it

Fertilizer is the engine of agriculture, but its inefficient use means that excess fertilizer ends up in our waterways, contaminating freshwater supplies and causing algae blooms, such as those that recently cut off water supplies to hundreds of thousands of residents in Toledo, OH. In addition to impacts on communities, algae blooms also affect ecosystems, killing millions of fish and harming the seafood and recreation industries.

Nutrient runoff from fertilizer is a problem that many stakeholders, including farmers, have been trying to fix for many years, both in the Western Lake Erie Basin and beyond. The efforts to date have had a real impact, but that impact has not been nearly enough to solve the problem of dangerous and costly dead zones.

We need to do much more at a much larger scale, while also increasing productivity to feed a growing population.
