Heterogeneity was found in the distribution of agricultural land areas with different contents of available P, exchangeable K and acidity. Soil areas with low content of available P and high content of exchangeable K are dominant: more than 60% of the soils require liming. Seven agrochemical types of plowed lands are distinguished. The data available may be used for planning the application of fertilizers.
