System of Diagnostic Indicators for Low-Productive and Degraded Soils to Assess Their Suitability for Afforestation

Authors

Abstract

The soil indicators and parameters of forest productivity of low productivity and degraded soils are determined, on the basis of which the classification of soils based on the degree of their suitable for afforestation has been developed. The suitability of soils for afforestation were evaluated in three categories: suitable for afforestation, limitedly suitable and unsuitable suitable for afforestation.

The experience of afforestation of low-productive and degraded soils is generalized and a system of diagnostic indicators for their forest typological evaluation on zonal and morphological basis is proposed, and an information analysis on the problem of assessing the suitability for afforestation of low-productive lands (saline, stony, sandy) that are derived from agricultural circulation is provided. The suitability of soils for afforestation is described by a system of soil indicators, in particular, their particle size distribution, humus content, common and mobile forms of NPK, and exchangeable cations. However, among these indicators, one can single out informative indicators of the level of productivity of forest lands - mineralogical (chemical) and granulometric composition of soils. At the same time, it has been proved that the granulometric composition of the soil determines such important characteristics as the content of exchange bases, common forms of phosphorus, potassium, and humus.
