We assessed the current soil properties of Kazakhstan by sampling top soil (25 cm) at 40 sites between Petropavlovsk (North) and Taraz (South) during wet and dry seasons, and determined the top soils' physical and chemical compositions and related phenological properties at sampling sites.
Supplement 1 contains a folder with photos of landscape and vegetation for each sample location. The naming convention is location number. photo number (date the sample was taken). For example, 1.1(25.05.15) corresponds to location 1 and photo 1 on May 25, 2015. Supplement 2 is a Microsoft Excel file that contains spreadsheets with data on 1) soilTC, soil total organic carbon (TOC), soil total inorganic carbon (TIC), 2) Loss on Ignition (LOI), 3) soilTN, 4) soil dry bulk density, 5) gravimetric and volumetric soil moisture 6) soil suspension and supernatant pH; 7) soil electrical conductivity, and 8) soil TOC and TN 9) annotation table (Table 1). Values of sample measurements from each location were reported with standard deviation (STDEV) and standard error (SE) when applicable.
