Soil properties and productivity plantations of tilia cordata in various forest conditions

Abstract

In Belarus there are 341.8 ha of plantations with linden artificially-descent and 3,746.2 ha of natu-ral origin. Lime stands are distributed unevenly through the territory of the Republic and by class of age. The largest area with Linden widespread in the subzone of broadleaved and spruce forests (3,229.4 ha). There is a predominance of middle-aged stands (the average age is proportional to the square – 45 years). Lime stands grow mainly in oxalis (72.5% of the total area) and snidely (22.4%) forest types. To study the productivity of plantations and soil properties were mortgaged plots in stands of various composition and origin in different types of forest growing conditions and forest types (linden oxalis, blueberry and fern). For each horizon of the soil gr anulometric composition, co ntent of humus, mobile forms of phosphorus, exchange potassium, iron rolling, the exchange cations of calcium and magnesium, acidity, calculated cation exchange capacity and saturation of soil bases. As a result of the research showed that the lime stands grow on sandy, sandy loam, sandy loam, underlain by clay and loamy soils. The higher average gains on a stock are pure and mixed lime stands of artificial origin, planted on sandy loam, underlain by loam and loamy soils in various forest types.
