中文名称：田间矿质土壤中有机碳和氮储量及其变化测定指南
英文名称：Guidelines for the determination of organic carbon and nitrogen stocks and their variations in mineral soils at field scale
发布日期：2021-10
标准范围
This document presents a method to quantify the soil organic carbon and nitrogen stocks in mineral soils at plot scale. It also provides guidance on how to detect and quantify simultaneously the variations of carbon and nitrogen stocks over time in mineral soils at field scale. It is based on several documents [2],[3],[4],[5],[6],[7],[8] already published .
This document does not apply to organic soils, soils with permafrost, wetland soils, or to soil layers prone to submergence below the groundwater table.
