Abstract

This work aims to evaluate the relations between total as well as DTPA extractable Fe, Mn, Zn and Cu and each of soil texture, CaCO3, organic matter (OM) and CEC of soils adjacent to lakes of Idku and Maryut in the northern west of Nile delta. Thirteen soil profiles representing the main types of soils both areas were examined. The obtained results could be summarized as follows: Total Fe ranged between 20000 and 43000 mg kg-1 while available Fe varied from 1.8 and 22 mg kg-1. Contents of both forms decreased with depth. Total Mn ranged between 500 and 2800 mg kg-1 while available Mn varied from 3.0 to 35.4 mg kg-1. Total Zn ranged between 75 and 275 mg kg-1 while available Zn varied from 0.2 to 4.6 mg kg-1. Total Cu ranged between 37.5 and 225 mg kg-1 while available Cu varied from 1.0 to 32.2 mg kg-1. Significant negative correlations occurred between total content of each of the studied micronutrients (Fe, Mn, Zn and Cu) and each of soil pH, sand %, gypsum % and CaCO3 % and also between available Fe and soil pH; between available Mn and each of soil pH, ESP and sandy %; between available Zn and each of soil pH and ESP; between available Cu and each of soil pH and sand %. Significant positive correlations occurred between total contents of the micronutrients (Fe, Mn, Zn and Cu) and OM % as well as clay; between available micronutrients (Fe, Mn, Zn and Cu) and OM %, clay % and CEC. The data of the statistical measures showed that, the highest values of weighed mean (W) of total Fe, Mn and Cu were found in the soil profiles of sandy beaches, while, the highest values of W of Zn total were found in the soil profiles of recent Nile Alluvial. The trend (T) indicates that some of the soil profiles were highly symmetric distribution with respect to Fe, Mn, Zn and Cu. The calculated values of specific range (R) of the total content of all micronutrients under study revealed that, the studied soils were composed from homogenous materials. The soil fertility of the studies available micronutrients (Fe, Mn, Zn and Cu) seemed to be more than the critical levels.
