Soil Carbon and Nitrogen of Northern Great Plains Grasslands as Influenced by Long-Term Grazing

Three mixed prairie sites at Mandan, N.D. were grazed heavily (0.9 ha steer-1), moderately (2.6 ha steer-1), or left ungrazed (exclosure) since 1916. These sites provided treatments to study the effects of long-term grazing on soil organic carbon and nitrogen content and to relate changes in soil ca... View More
