Influence of Cropping Systems on Soil Properties in Semi-arid Conditions of Setif, Algeria

Journal of Agricultural Science and Technology(A) 2013年第8期3卷 653-658页

The effects of two culture systems, conventional and no-till combined the previous crop （lentil and wheat） on soil properties were studied in the experimental site of the station Technical Institute for Field Crops （ITGC） Setif （Algeria） during the crop year 2011/2012. The results indicate that the no-till system affects positively the variables of soil properties and the organic matter has a rate of 2.89% compared to 2.44% in conventional tillage. If the conventional system has an infiltration of moisture relatively higher than that observed for no-till throughout the cycle, the no-tillage is distinguished by a higher storage of moisture at the end of cycle wheat cultivation. The results also indicate that the density （1.44 g/cm）, permeability （22.79 cm/h） and soil compaction （12.51 kg/cm） in no-till were significantly higher compared to conventional tillage 1.35 g/cm, 14.13 cm/h, 7.40 kg/cm, respectively.

关键词： Conventional tillage no-ill preceding crop bulk density infiltration compaction organic matter.

Single-Stage Repair of a Critical Aortic Coarctation, a Bicuspid Aortic Stenosis and an Ascending Aortic Aneurysm

We report a 26-year-old man with critical aortic coarctation, severe bicuspid aortic valve stenosis, infective endocarditis and ascending aortic aneurysm. He underwent simultaneously in singlestage a Bentall’s procedure and an extra-anatomic ascending-descending aortic bypass grafting by 14-mm Dacron tube, through median sternotomy. The immediate postoperative outcome was favourable. The CT scan control for 7 years after surgery showed a good patency of the extra-anatomic bypass.
