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
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
