In our study, we did seven treatments and one control T0 (sand); T1 (sand and organic matter); T2 (sand and nitrogen); T3 (sand and bio-charbon); T4 (sand, bio-charbon and organic matter); T5 (sand, bio-charbon and nitrogen); T6 (sand, bio-charbon, nitrogen and organic matter); T7 (sand, organic matter and nitrogen) with three randomized full-block repeats Physical, chemical and biological soil analyzes were performed with barley plant biometrics measurements. The results obtained from this study show that there is a positive evolution of bio-charbon on the physical and chemical properties of soil and the growth of plants and their yield. The best results were in T4 (Sable, bio-charbon and organic matter) and T6 (Sable, bio-charbon, nitrogen and organic matter.( The results of this study confirmed the possibility of improving the properties of the sandy soil of the El-Oued region and increasing the growth of the barley plant.frSol sablonneux amélioré, biocharتربة رملية محسنة ، الفحم الحيويMaster
