ترجمة الملخص

The target of this research is to study the effect of different systems of plowing on soil content of the mineral nitrogen and the organic substance and the effect of these systems on formation and stability of soil granules or soil complexes.The research was held in the international center for agricultural researches in the dry regions (ICARDA) in "Tel Hedia" region where soil samples were gathered from experimental pieces in which systems of studied plowing were applied since ten years within a binary agricultural course wheat _ lentil, the soil samples contained some treatments to which nitrogen was added, and treatments which nitrogen was not added to, it also contained treatments that crop residues were removed and others in which the crop residues were kept after harvest, the soil samples were gathered in three times before seeding, during seeding and after harvesting and at three depths (0-25 cm), (25-60 cm), and (60 -100 cm).The mineral nitrogen was estimated for these samples using the "instillation" method then calibration by sulfuric acid in the international center for agricultural researches in the dry regions (ICARDA), the organic substance was also estimated in the soil samples through humid oxidation by "potassium dichromate" and then calibration by "mor salt: Ammonium sulfate ferric disulfide" , while the stability of soil complexes was estimated through the two methods of "humid sift" and "dry sift" using sieves of different diameters in the laboratories of the agriculture faculty at Aleppo University.It was achieved that in theperiod before cultivation the surface treatments of plowing has exceeded and seeding without plowing at traditional plowing treatment in the soil content of mineral nitrogen ,means that retention of mineral nitrogen in these treatments was bigger than that of traditional plowing treatment in the treatment to which nitrogen was added, while in the treatments to which nitrogen was not added, it's noted that no big difference in mineral nitrogen quantity in most treatments at different depths. But in the period of adding through seeding, it's often noted that superiority of seeding treatment without plowing whether residues were removed or kept on other plowing treatments when nitrogen is added, but when nitrogen is not added, it is often noted that no big differences in mineral nitrogen among plowing treatments.But during the period "after plowing", we also noticed that superiority of seeding treatment without plowing to other plowing treatments concerned mineral nitrogen saving in the soil when nitrogen is added ,while when nitrogen is not added we noticed no big differences concerned nitrogen As for the organic substance ratio in the soil, it was superior in seeding treatments without plowing to that in the other studied plowing treatments, as noticed, because plowing oxidizes this substance fast through exposing it to the surrounding atmospheric conditions when flipping. But as for the soil complexes, it is noticed that it was more stable and has bigger diameter in seeding treatments without plowing becauseit is not exposed to smashing through plowing, thus it is more resistant to soil erosion.finally, it must be noted that using or following such cultivation systems without plowing or decreasing of plowing processes improves soil properties and its ability to keep the necessary alimental elements for plant existence, it also blocks collapse of soil structure and saves its complexes, thus, it improves soil quality, and following of reduced or zero plowing systems helps save time, potential and fuel, it improves ecological conditions, it would also reduce soil erosion processes through improving its physical and chemical properties
