From: Lignin and cellulose dynamics with straw incorporation in two contrasting cropping soils
The structural equation model (SEM) showing the relationships among dynamic of cellulose or lignin, enzyme activity, microbial gene abundance, pH, available nitrogen (AN) in upland and upland-paddy rotation land, and their standardized total effects (direct plus indirect effects) derived from the SEMs (shown in the right corner of sub-figures). The width of the arrows indicates the strength of the standardized path coefficient. The solid lines indicate positive path coefficients and dashed lines indicate negative path coefficients. R2 values represent the proportion of the variance explained for each endogenous variable.
