ESTIMATION OF TEA CROP ADAPTIVE POTENTIAL IN THE CONDITIONS OF ADYGEI

abstract 0871303031 issue 87 pp. 396 – 407 30.03.2013 ru 1717
Such agrochemical and agrophysical properties of soils as base saturation degree, number of fine sand and dust fractions, as well as of physical clay limit the tea crop productivity in the Maykop region and in damp subtropics of Russia. Multiple regression models of their close influence on tea plantations productivity have been obtained

PRODUCTIVITY FORECAST OF BROWN FOREST SOILS FOR TEA CULTIVATION IN ADYGEA BASED ON MODERN EVALUATION METHODS

abstract 1191605015 issue 119 pp. 227 – 237 31.05.2016 ru 927
Increasing of tea production in the foothills of Adygea should be based on potential soil properties suitable for tea plant. The goal was achieved using modern methods of soil evaluation of tea plantations. The evaluation criteria were the following agrochemical and agro indicators: soil acidity (pH KCl); hydrolytic acidity; the sum of exchangeable bases; bases saturation; granulometric composition. It was found that the soil under tea plantation in Adygeya classifies as brown forest poorly unsaturated with the level of potential fertility rated as satisfactory (bonitet rating 40-60). However, the low supply of nutrients in the layer 0-40 cm: phosphorus (19,04 ± 2,42 mg / 100 g soil), potassium (17,70 ± 1,60 mg / 100 g soil) and a sufficiently high degree of saturation of soil bases in the layer of 50- 100 cm (67,10 ± 11,67%) in combination with a soil moisture deficit determine their low productivity of 16,0 ± 5,0 kg / ha, whereas their potential productivity of 30-50 t / ha. The development of scientifically grounded, targeted ameliorative and agro-technical measures (irrigation, nutrition systems using physiologically acidic forms of nitrogen and potash fertilizers that reduce the degree of saturation of the soil bases) will help to increase the effective soil fertility and allow the tea plants reach its biological potential and achieve predicted productivity in Adygea region
