The standard substances for soil composition of agricultural land (GBW 07913~GBW 07942) were developed based on comprehensive consideration of soil types, topography, and pollution characteristics of agricultural land in China. A total of 30 agricultural land soil samples were collected from regions such as North China (Beijing, Shanxi), Northeast China (Liaoning, Heilongjiang), Northwest China (Shaanxi), Southwest China (Guizhou), and East China (Anhui, Jiangsu, Fujian, Shandong). The fixed value indicators of this series of standard substances include a total of 65 indicators for soil heavy metals and rare earth elements, as well as deep soil control indicators. They are suitable for technical work such as instrument calibration, analysis method confirmation and evaluation, measurement process quality control, technical capability assessment, and analysis result arbitration in the analysis of soil related components in agricultural land.

Fixed value methods: Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); Atomic fluorescence spectroscopy (AFS), ion chromatography, atomic absorption spectroscopy (AAS), ion selective electrode method (ISE), volumetric method (VOL), spectrophotometric method (COL), gravimetric method (GR), etc.

This standard substance is packaged in brown glass bottles with good sealing properties, wrapped in plastic bottles, with a weight of 50g per bottle. It is stored in a dry and cool place at room temperature. Shake well before use to ensure uniformity, use as soon as possible after opening, and strictly prevent contamination during use.
