Poor water quality has been a persistent challenge in agriculture, particularly due to sediment and nutrient loss from farmland. There are some restrictions on timing and amount of manure and/or nitrogen application in some locations, but enforcement is minimal and the 4Rs are voluntary. That brings us to in-field management.
In addition, large concentrated animal feeding operations, which have become more prevalent there in recent years, add to the problem by disposing millions of gallons of nitrogen-rich liquid manure. And when nitrates are present, it’s inevitable that other contaminants, such as pesticides , are also polluting the water.
They’d take a few hundred acres of both leased and family-owned central-Texas farmland—land that for decades had grown row crops of corn and cotton—and give it “what it wants back,” he said. See full series Back around 2011, Jonathan Cobb and his wife, Kaylyn, had what he calls a “simple game plan.”
As farmland becomes less functional as a result of increasing stresses from drought, floods, pests, and heatwaves, its regulation by diverse organisms becomes ever more important. The mix fixes nitrogen and livestock can graze the mix directly in the field, returning nutrients to the soil via manure.
By Trina Moyles Glen and Kelly Hall have been managing Timber Ridge Ranch, a 480-acre farmland situated an hour south of Calgary near Stavely, Alberta, for over 40 years. Our cover crop cocktail has resulted in an immense reduction in synthetic fertilizers, herbicides, and pesticides.
In 2006, they began to look for farmland around Edmonton, but the exorbitant cost of land — in some areas, upward of a million dollars — was insurmountable on teacher’s salaries. Then, we planted green manures and cover crops to help build up the topsoil again, which had been pretty depleted over the years. It was literally cooking.
By ‘lack of humus’ he is referring to the increasing trend, even then, to dispense with returning organic matter to the soil, for example, in the form of composted farmyard manure, that was made possible by the development of synthetic fertilisers. When it comes to protection against disease, the picture is even less clear.
Large farms now control 42 percent of the farmland in the country. On February 6, a federal court stopped the spraying of the controversial pesticide dicamba across millions of acres of cotton and soybeans. That 7 percent decline “is a larger percentage decrease than what has been seen in the last 20 years,” said NASS’s Bryan Combs.
40 Acres & A Mule Project , United States 40 Acres & A Mule seeks to acquire Black-owned farmland to be used to celebrate and preserve the history, food, and stories of Black culture in food and farming. American Farmland Trust (AFT) , United States AFT is dedicated to protecting and preserving farmland and ranchland in the U.S.,
Sir Albert Howard, who developed the scientific aerobic composting method and brought it to the world in his iconic 1943 book, An Agricultural Testament , wrote “Artificial manures [that’s what he called chemical fertilizer] lead inevitably to artificial nutrition, artificial food, artificial animals, and finally to artificial men and women.”
Meanwhile, in the Netherlands, the same farmers struggling with the effects of climate change, like drought, are revolting against stricter regulations on pollution from livestock manure. In a world where we need to feed a lot more people, meat…will still be demanded and exacerbating climate change and deforestation,” Muzi said.
million acres of farmland are involved as of January 2025. billion in 7,200 on-farm renewable energy projects, including installing manure digesters and solar panels and $6 billion in rural electric coops. According to the USDA, more than 21,000 farms and 5.2 Bidens USDA also invested $2.2 Because most GMO corn exported from the U.S.
