soil total organic carbon

基本解释

Soil total organic carbon decreased 8.3% and 11.2% for nitrogen and no fertilizer treatments.
單施氮肥和不施肥土壤縂有機碳有所下降，降幅爲8.3%和11.2%。
Soil total organic carbon was negatively correlated with depth of soil, is not significant difference among soil layers in NTS.
NTS的土壤全碳含量與土層深度顯著負相關，各土層間的全碳含量差異不顯著。
Results showed that there were no significant differences in soil total organic carbon, soil moisture content, pH and soil microbial biomass phosphorus in each soil layer between the two plantations.
結果表明，在各個土層中，兩種林分下的土壤含水量、pH值、有機碳的含量以及微生物生物量磷均無顯著差異。
