El-Kharga oasis, New Valley governorate is a promising area for increasing the cultivated areas in upper Egypt. This area has variations insoil texture and chemical properties so that its contents of plant essential nutrients may become at concern .The aim of this study is to investigate the available phosphorus content of some soils of El- Kharga oasis and its relation with soil texture and some other soil properties.So,thirty nine soil samples were collected from 13 soil profiles representing 5 different locations.Three soil samples from three layers (0-20, 20-40 and 40-60 cm) were taken from each profile.
The results showed that the available soil phosphorus ranged from 4.40 to 34.54mg kg-1. Levels of available P were low (< 6 mgkg-1), medium (6 -10 mg kg-1) and high (>10 mg kg-1) in 10.26, 35.90 and 53.84 % of the soil samples, respectively .The average available P level differed withsoil texture. It was 16.38, 13.41, 12.13, 9.25 and 7.66 mg kg-1 in sand, loamy sand, sandy loam, sand clay loam and clay textured soil samples respectively. Insignificant negative correlations were obtained between the available P and most of the discussed soil properties (clay fraction, OM, SP, ECe, CaCO3, soluble Ca and soil depth) with r values of (-0.2729,-0.2074, -0.3257,-0.2121,-0.0985, -0.2047 and -0.3905) respectively, except soil pH, sand
