Eco-Agrochemical Indicators of Degradation of the Soil-Vegetation Cover of Tundras and Their Practical Application

摘要

The authors give a description and application of empirical equations for characterizing correlations between the agrochemical properties of soils and tundra vegetation parameters, which help determine the acidity level, content of total nitrogen, humus, mobile nitrogen, phosphorus, and potassium in soils of undisturbed and disturbed lands of tundra landscapes. Calculation-based indicators are established for the assessment and prediction of soils' eco-agrochemical condition as a result of differentanthropogenic impacts; the authors also suggest methods for their identification and development of techniques for recurvation (norms of soil hming and fertilizer dosage).
