Impacts of Cropping Systems and Long-Term Tillage on Soil Microbial Population Levels and Community Composition in Dryland Agricultural Setting
Figure 1
Abundance of bacteria (a) and fungi (b) along with bacterial : fungal ratios (c), as determined by qPCR, in soil under different long-term tillage and rotation treatments. Error bars represent ± standard error of three replicate samples. NT: no tillage; CT: conventional tillage; CW: continuous wheat; RW: sorghum-wheat-soybean rotation. Different uppercase letters above bars within a figure indicate significant differences at .
