Impacts of Cropping Systems and Long-Term Tillage on Soil Microbial Population Levels and Community Composition in Dryland Agricultural Setting

Figure 2

Cluster analysis of bacterial community structure under different long-term tillage and crop rotation treatments. Branch lengths illustrate dissimilarity values (1-Yue-Clayton similarity), with shorter branch lengths representing greater levels of similarity and longer branch lengths representing increasing dissimilarity. NT: no tillage; CT: conventional tillage; CW: continuous wheat; RW: sorghum-wheat-soybean rotation.
