From: Mechanisms of carbon and nitrogen distribution in soil aggregates in response to soil conditioners
Structural equation model of Soil chemical properties, aggregate stability, and yield. On the left: the thickness of the lines indicates the size of the influence, and the numbers indicate the path coefficients between different variables. Dashed and solid lines show positive and negative relationships. R2 was the variance ratio, χ2, P, IFI, CFI, RMSEA and AIC were the model fitting parameters. The indicators in the diagonals on the right represent aggregate stability (A.S) and the distribution of soil aggregates. Red indicates a negative correlation, while blue indicates a positive correlation. ** -mean P < 0.01.
