| Abstract | ||||
| The current study aimed to investigate and evaluate the status of the major macro and micronutrients in soils of the area adjacent to west of the Nile Delta. This area have two main physiographic units namely, river terraces and Wadi El-Natrun complex. The results showed that, available nitrogsen contents vary from low to medium limits and correlated mainly with organic matter contents. Available phosphorus contents generally, tend to be in low levels having positive and significant correlation with soil salinity, lime clay and silt. Available potassium contents appear limits from low to high, having significant positive correlation with lime, soil salinity, clay and silt contents. Available iron differs from low to high limits and have positive and significant correlation with clay and silt. Available manganese contents record low level along side moderate and have positive and significant correlation with clay, silt, salinity and gypsum. Available zinc contents are similar to available manganese. Available zinc have a positive and significant correlation with organic matter, clay, soil salinity and lime contents while gypsum contents show an opposite relationship. Available copper contents, generally, appear low levels, which have positive and significant correlation with organic matter, clay , salinity and lime contents. Requirement of both annual and perennial crops show that available nitrogen show low levels, while available potassium differ widely between low and high levels. Available iron ,manganese and zinc change from low to medium, while available phosphorus and copper are in low levels. Distributions of different levels of the studied nutrient elements and their areas in the surface layers of the studied soil are presented on physiographic maps using GIS technique. | ||||
