Agricultural intensification and a lack of regulations drove a 78-percent increase in the farm sector’s ammonia emissions between 1980 and 2018, according to a paper published by The Proceedings of the National Academy of Sciences on Monday.
The method that farmers use to apply manure to their fields can affect emissions of greenhouse gases during the winter, say researchers from the University of Vermont. Their study, published in the Soil Science of America Journal, is one of the first to look at greenhouse gas emissions from Vermont farmland and highlights the consequences of different manure-spreading methods.
Days after a federal judge dismissed a lawsuit by the Des Moines Water Works against farm runoff, the City Council voted to support a bill in the Iowa House allowing regionalization of the water utility, said the Des Moines Register. The chief executive of the Water Works says the regionalization bill, sponsored by a legislator who is a hog farmer, is retaliation for the lawsuit, which wanted to apply water pollution laws to agricultural runoff.
