LEEDS, N.D. (AP) - A new business in northern North Dakota is turning bison waste into nutrient-rich fertilizer that can be used for landscape, turf, garden and houseplant applications.

Buffalo Earth partners with a neighboring bison feedlot near Leeds, the Devils Lake Journal (https://bit.ly/1hJl6QT ) reported. In June, the business received a $135,000 award from the North Dakota Agricultural Products Utilization Commission, and it recently learned it has been approved for the Pride of Dakota Holiday Showcase.

Through a process that can last up to three months, Blue Earth takes mounds of bison manure generated by the feedlot and turns it into rich, black fertilizer.

Manure is spread out into lines, which are 200 feet long, 12 feet wide and 8 feet high, and then those lines are heated three times to 160 degrees Fahrenheit, destroying many of the impurities. The material is sifted to remove further debris, leaving only the nutrient-rich soil behind. The final product is sold in bulk and in small steeping bags that people can use when watering their houseplants or garden.

The conversion from waste to fertilizer takes about eight to 12 weeks because the manure must rest for four weeks after every time it’s heated.



The business has worked with the North Dakota State University Extension Service in developing the fertilizer, allowing it to further its mission of producing an environmentally friendly soil that reduces the need for inorganic fertilizers.

Buffalo Earth’s recycling process reduces waste on the feedlot by 60 to 70 percent.
