As it is noted in some literature if vegetation cover increased as far as two times soil erosion would be diminished so far as 8 to 32 times. Plant growth and f1evelopment in eroded soil is confronting two major . difficulties one' is related early stage of plant growth in which lack of moisture in soil is the main issue, another problem is about relative and absolute dry periodes which causes ceasing or interfering plant growth. So, to solve these problems if we find any procedure for providing soil moisture, decreasing run off and using a.' manner for keeping water in Soil by which water release to plant gradually, then . plant growth difficulty will be removed. BT53 polymer can help plant, to &rdquoestablish survival in early and other growth stages by adding waterho/ding capacity and preventing surface soil erosion. In order to study the effect of this prlymer on soil erosion and soil water reservation capacity in different slops 6 treatments in 3 replicates for each were considered in viewing to hydroclimatic conditions of the region.
