Abstract

Surface (0-30 cm) and subsurface (30-60 cm) soil samples were collected from El-Zayat area, New Valley Governorate, Egypt to asses soil physical and chemical properties, and fertility as well as the relationships among these soil properties. The results revealed different soil texture classes (clay, sandy clay loam, clay loam, sandy loam and silty clay loam). The calcium carbonate and organic matter contents varied from 9.8 to 85.6 and from 0.8 to 10.2%, respectively. Cation exchange capacity (CEC) ranged from 4.8 to 71.6 cmol/ kg with an average value of 34.92 cmol/ kg. The pH values differed from neutral to moderately alkaline. Additionally, 10% of the collected samples were slightly saline, while 30.0 and 60.0% were moderately and strongly saline, respectively. Sodium adsorption ratio (SAR) for 70% of the collected samples realized values > 13 indicating sodic soils. The total nitrogen in the tested soil samples is very low. Concerning available phosphorus, about 53, 30 and 17% of tested soil samples were low, medium and high, respectively. The available potassium (K) for 98% of the tested soil samples was very high. Suitable gypsum requirements should be added to reclaim these soils which need a management program to overcome these problems. Also, organic manures have to be applied to improve the soil properties and enrich their nutrient status.
