EFFECT OF DRIP IRRIGATION ON SOIL SALINIZATION
06.00.00 Agricultural sciences
DescriptionThe article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization

Description
The effect of glue filling of internal voids of the surface tracheids and their relative position in the radial wood surfaces gluing on the strength of adhesive joints is theoretically considered. It is shown that for the maximum joint strength it is necessary that the amount of deposited adhesive provides filling of all cavities tracheids of wood surface and formation of the intermediate layer between the substrates
