Pearson correlation coefficients among various variables of (a,c) unfertilized and (b,d) fertilized tea plantations of Camellia sinensis var. assamica and Camellia sinensis var. sinensis. The pie charts in the upper right indicate correlation strength, and the numbers in the lower left are the correlation coefficient. CSA, Camellia sinensis var. assamica; CSS, Camellia sinensis var. sinensis; SOC, soil organic carbon; SMC, soil moisture content; NO3−-N, nitrate nitrogen; NH4+-N, ammonium nitrogen; SAP, soil available phosphorus. Significance levels: ***P < 0.001, **P < 0.01; *P < 0.05.
