N1 - Funding Information:
This research was supported in part by the grant “Kazakhstan soil microbiome: agricultural characteristics and perspectives” in the framework of the agreement #104 dated 12.02.2015 of the program #055 “Scientific and/or Scientific-Technical Activities” within subprogram #101 “Research Grant Funding” from the Ministry of Education and Science of the Republic of Kazakhstan and by Nazarbayev University. We thank Jong Kim for letting us use the equipment of Department of Civil and Environmental Engineering, Almagul Kushugulova and Samat Kozhakhmetov for administrative and managerial support and Nurlan Ongdas for helping to collect field samples. We are grateful for the valuable input and assistance provided by Drs. Joanna Clark, Tom Sizmur, Maria Shahgedanova, and Anne Verhoef at University of Reading.

N2 - Kazakhstan's soil properties have yet to be comprehensively characterized. We sampled 40 sites consisting of ten major soil types at spring (wet) and late-summer (dry) seasons. The sample locations range from semi-arid to arid with an annual mean air temperature from 1.2 to 10.7 °C and annual precipitation from less than 200 to around 400 mm. Overall topsoil total (STC), organic (SOC), and inorganic (SIC) carbon did not change significantly between spring and late summer. STC and SOC show a wave like pattern from north to south with two maxima in northern and southern Kazakhstan and one minimum in central Kazakhstan. With a few exceptions SIC content at northern sites is generally low, whereas at Lake Balkhash SIC can exceed 75% of STC. Independent of the seasons, SOC significantly differed among soil types. Total nitrogen content distribution among our sampling sites followed a similar pattern as SOC with significant differences between soil types occurring in northern, central and southern Kazakhstan.
