Study: Manure is the Lifeblood of Soil

How is soil quality affected by manure, compared with inorganic fertiliser? This study at the University of Wisconsin aimed to find out.

From 2003 to 2015, the research team applied either manure or inorganic fertilizer to field plots growing corn and soybeans. They used low, medium, and high manure levels, and medium and high inorganic fertilizer levels. They also had a control treatment of no soil additives to provide a comparison.
