One of the promising areas associated with a large amount of information on the properties, characteristics and classification of soils is soil Informatics. Its appearance has allowed soil scientists, farmers and environmentalists to process data; to model soil processes, to make operational decisions on land use; implement systems to assess fertility, control of technological processes in agriculture. Currently multinational and global information systems are used, which contain data on soil profiles of many countries: European Soil Database, Europe; SOTER, global soil information system and others. Information systems at the national level study the soil characteristics of one country: Australian Soil Resource Information System; National Soil Information System (USA) and others. In order to generalize process and preserve information about soils of Russia accumulated by long-term research, a nationwide Soil-geographical database is being developed in our country. To optimize the agricultural activity of certain regions of the country, regional information systems are developed - Accounting and monitoring of agricultural lands of the Novosibirsk region, geoinformation system of the Tyumen region and others. Modern soil information systems, for the most part, are implemented through the use of the GeoRSS standard, which is based on a hypertext providing information on the Internet.
