求翻译：测定方法参见鲍士旦主编的《土壤农化分析》,其中土壤有机质含量用重铬酸钾容量法外加热法、pH值采用5.0:1.0水土比，电极测定、全N含量用半微量开氏法、、碱解氮采用扩散法吸收测定、速效P含量用碳酸氢钠浸提是什么意思？

See Baoshi determination Dan editor of the "agricultural soil analysis", in which soil organic matter content of potassium dichromate volumetric method with external heating method, pH, water and soil using 5.0:1.0 ratio, electrode determination of total N content with a semi-micro's method, , nitro
