Historical dataset of chemical properties of soil profile in the Balkhash lake area (2010)

Content of data: the chamical property database of seven sites of soil profiles in Balkhash Lake Basin.
Source of data: 2010 national science and technology cooperation project: the impact of climate change on land productivity in central Asia and soil investigation in balkhash lake region.
Data quality: The soil profile was stratified and sampled according to soil genetics. The analysis and determination items included: organic matter content, soil total nitrogen, carbon-nitrogen ratio, carbonate content, calcium carbonate content, and cation exchange capacity (Ca \ Mg \ Na \ K \ total), pH value, soil available nutrients (available phosphorus, available potassium and alkaline nitrogen) and so on.
Data application prospects: With precise coordinates, historical data can be compared.
Note: Sample point 1 and sample point 2 are 20 m away; sample point 3 and sample point 4 are 50 m away.
