Abstract. In article the negative impact of organic pollution from old suitable wooden cross ties is considered. The design for geoecodefense of soils from such influence is offered. It is shown that such design can be executed in the form of the porizovanny screen. The design sizes taking into account geoeco-protective properties of the porizovanny screen and coefficient of geoecological reliability are calculated.
