![]() Among columns receiving manure, the 20 g kg − 1 biochar treatments reduced total N and total dissolved P leaching by 11% and 69%, respectively. Measurements showed a significant decrease in the total amount of N, P, Mg, and Si that leached from the manure-amended columns as biochar rates increased, even though the biochar itself added substantial amounts of these nutrients to the columns. Repacked soil columns containing 0, 5, 10, and 20 g-biochar kg − 1 -soil, with and without 5 g kg − 1 of dried swine manure were leached weekly for 45 weeks. Our objective was to quantify the impact of biochar on leaching of plant nutrients following application of swine manure to a typical Midwestern agricultural soil. Little, however, is known about the effects of biochar applications on temperate region soils. Abstract: Application of biochar to highly weathered tropical soils has been shown to enhance soil quality and decrease leaching of nutrients.
