Abstract

The research purposed to study effect weathering properties in each location on fertility characteristic, and study relation with Soil properties. Complex soil at depth (0-30) cm were taken from Eight different locations in rainfall stability areas in the north and north east of Syria. including (Jueik, Hemo) the first rainfall stabilization area, (AL- hasakeh and Ras AL ein) the second rainfall stabilization area,and (Al-zahabeia, Balat) the third rainfall stabilization area, And (Khanaser,Ariesh) the fourth rainfall stabilization area. The study showed that the studied soils were different properties in its fertility characteristic as rainfall stabilization areas. Where the percentage of the clay and organic matter decreases from the first to the fourth rainfall stabilization area, which explains the role of the stability area in the distribution of the clay part distributed in proportion to rainfall range. While The percentage of calcium carbonate, and lime Active increases from the first to the fourth stabilization area. Also The study concluded strong positive correlation between Clay percentage and each organic matter,available phosphours Reached to (r²=0.90, r² =0.93) respectively. While available phosphours related strong positive with organic matter (r²=0.97), strong negative by calcium carbonate (r²=0.96).

Keywords: rainfall stability, fertility, calcium carbonate, clay, available phosphours.
