Ficus carica L. on terraced agro-brown soils of the Southern Coast of the Crimea

Abstract

The reaction of fig plants to the properties of agro-brown terraced soils of the Southern Coast of the Crimea (SCC) was studied, unfavorable soil properties for plants, as well as their optimal and permissible parameters were revealed. The dependence of the volume mass of fine grained soil on the content of silt particles and silt with fine dust in the layer of 0-60 cm and in the root layer was revealed. The quantitative dependences of fig tree trunk circumference on the properties of agro-brown terraced skeletal soil were revealed. The growth of figs depended on the depth of dense underlying rocks, fine grained soil reserves in the layer deeper than 60 cm, as well as in the root layer. Valid parameters are set for these values. The tendency to the dependence of the circumference of the tree trunk on the humus reserves in the root layer and the content of the skeleton in the layer deeper than 60 cm was revealed.
