Using different quantities of volcanic ash, soil samples were collected from the Al-Thahallah village from a depth of (0-30) cm, The experiment was designed according to the complete random design with one factor that represents the ash quantity (1.25, 2.5, 5) %, with three replicates for each treatment in addition to the control treatment a0. The experiment was carried out within the plastic pots during agricultural season 2018/2019, in which the wheat of the Sham variety 3 were cultivated as a cover plant. The results showed that the addition of volcanic ash at the quantity of 5% led to a significant increase in the infiltration rate by (328.60) %,%, where the filtration rate increased from 0.42 cm/hr -1 to 1.80 cm.h-1, as well as for each of the air porosity by (89) % and the volum...

Several greenhouses were randomly distributed in different areas in Jableh city based on the period of their investment (5, 10, 20, and 25 years), as the investment period was considered the variable factor between greenhouses. The homogeneity of greenhouse texture was taken into consideration as much as possible. Two-layer soil samples were collected (0–20 and 20–40 cm). Electrical conductivity, pH, the ratio of organic matter and the major basic elements (nitrogen, phosphorus, and potassium), and the total cadmium and nickel in the soil, plants, and cucumber fruits were determined. SPSS was used (completely randomized design). The results showed that there was pollution of greenhouse soils with the elements cadmium and nickel in a manner that is proportional to the inc...

Six profils ont ete compares correspondant a un sol non sale cultive et draine, trois sols desales, draines et cultives et deux sols sales non irrigues et non draines. Les resultats montrent que les sols sont calcaires et de composition granulometrique argilo-limoneuse a limono-argileuse. La composition mineralogique des argiles est homogene avec la presence de kaolinite, d'illite, de chlorite et de mineraux 2:1 a caractere smectitique en proportion similaire. L'argile du sol est une beidellite. Les analyses chimiques ainsi que la drx montrent que les sols sales contiennent de fortes accumulations en sels et nacl domine. Les cec du sol a ph = 7 sont 25% inferieures a celles obtenues avec la cobaltihexammine. La methode au cobaltihexammine apparait mieux adaptee a la mesure de la cec et des cations echangeables.
