Opanasenko N. Е. Skeletal soils and fruit cultures. – Kherson, 2014. – 335 p.

A number of slices of roots of fruit and nut cultures are thoroughly analysed  in the paper. The architectonic schemes of plant root system along the profile are presented. In the gardens for the each breed of the growing cultures the test indexes of terms  of their optimal growing are given, namely on the dense underlying rocks, in plantaged conditions, in the conditions of buried humus horizons. The power of root systems is examined, depending on the degree of fine earth and humus reserves. The scale of stability growth for the cultural garden plants of Crimea and many other indexes are set: water content in leaves, water intensity of leaves, real water deficit, water loss of leaves, indexes of the productivity, statistical indexes, productivity on the rootstock, hydrothermal coefficients, description of the south black earth,  possible and optimal parameters of the power of the root layer, productivity on black earth, description of the foothill ordinary black earth,  indices of growth and productivity. All data of the grown trees, fruit and fruit and berry cultures pass a statistical treatment with the information about the indexes of the trees’ growth and productivity dependence from the properties of the skeletal soils. At the end of the chapter the theoretical conclusions and the direct recommendations for the practical workers of garden economy are given.
