Table 8 Coefficients of the regression model for decomposition rate

Model		Unstandardized coefficients		Standardized coefficients	t	Sig.
Model		B	Std. error	Beta	t	Sig.
1	(Constant)	129.946	13.642		9.525	.001
	Precipitation	.015	.010	.089	1.545	.130
	Atmospheric temp.	−1.413	.140	−1.084	−10.126	.001
	Humidity	−.077	.044	−.059	−1.742	.089
	Soil temperature	.808	.239	.173	3.377	.002
	Soil pH	−17.737	2.008	−.297	−8.835	.001
	Days of decomposition	.812	.058	1.604	14.104	.001

The regression equation is as follows:
Y_TBS = 129.946 + .015_Preci − 1, 413_ATMOSTEMP − 0.77_Humidity + .808_SoilTemp − 17.737_SoilPH − 17.737_Time + ε_x
Predictors: (constant), days of decomposition (time), soil temperature, soil pH, humidity, precipitation, atmospheric temperature
Dependent variable: decomposition (TBS)
