2 Environmental variables in dry and rainy seasons between two
locations of rubber tree soils. The significant differences between
seasons and locations were detected by two-way ANOVA. WC: Water content,
SOM: Soil organic matter, pH: Soil pH, AN: Ammonium nitrogen, NN:
Nitrate nitrogen AP: Available phosphorus, AK: Available potassium, TN:
Total nitrogen, TP: Total phosphorus, TK: Total potassium. *, P < 0.05; **, P < 0.01, ***, P < 0.001
