Nitrogen condition of Primorskiy Krai arable soils in the period of agricultural production increased intensification

The nitrogen condition analysis of Primorskiy Krai arable soils, formed as a result of anthropogenic impacts of various types and intensity over the 1970 - 1995 period is presented in the article. The analysis is performed in relation to soil types and agrochemical state groups (ASG). The predominant role of the latter in the formation of nitrogen levels in heavy texture soils is shown.
