soil total organic carbon

基本解释

Soil total organic carbon decreased 8.3% and 11.2% for nitrogen and no fertilizer treatments.
单施氮肥和不施肥土壤总有机碳有所下降，降幅为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的土壤全碳含量与土层深度显著负相关，各土层间的全碳含量差异不显著。
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.
