Studies on soils of Toshka region : 1- status of some nutrients in virgin soils of Toshka region [electronic resource]. دراسات على أراضى إقليم توشكى : 1-مستوى المغذيات النباتية فى أراضى بكر من إقليم توشكى. p.1425-1436. Includes references. Fifteen surface soil samples representing the different mapping units, were collected of virgin soils of Toshka area, •bounded by longitudes 30°00 ́ and 32°00 ́ east and Latitudes 22°22 ́and 23° 26 ́ north. Their physicochemical characteristics were determined using the standard procedures. In general, these soils are characterized by medium texture and their salinity widely varied between slight saline to extremely saline. More or less, these soils are calcareous in nature with mildly alkaline soil pH, poor in N,P and K contents. Moreover, the soluble cations and anions contents showed general distribution pattern of Na⁺ > Ca⁺⁺ > Mg⁺⁺ > K⁺ and Ci > SO4 > HCO³-, respectively. In addition, the total amounts of the tested micronutrients are found in the order of Fe > Mn > Zn > Cu, while their DTPA-extractable amounts, could be considered adequate-marginal for Fe, marginal for Zn and Low for both Mn and Cu.
