STUDY OF CHEMICAL CHARACTERISTICS OF SOIL AND RELATIONSHIP BY SOME ELEMENTS BEHAVIOR IN EL KAWAMEL, SOHAG, EGYPT

ABSTRACT
This research was aimed to know the chemical characteristics of the soil and its relationship with the behaviour of some elements in El Kawamel - Sohag - Egypt. Therefore, seventeen soil samples were collected representing six profiles representing the study area.
The results showed that: - The texture of the soil in El Kawamel soil is sandy in all soil samples. The cation exchange capacity ranged from 4.2 to 5.9 Cmol_cKg^-soil .The soil pH ranged from 7.61 to 8.79 (alkaline to slightly alkaline), therefore the electrical conductivity ranged from 0.15 to 6.97 dS/m at 25⁰C. The total calcium carbonate content ranged from 10.46 to 46.85 gKg^-1.In addition the order of the soluble cations content was as follows: Sodium > Calcium > Magnesium > Potassium. The soluble anions content was arranged as follows: - Sulphate > Chloride > Bicarbonate, while the carbonate anion was absent. The results also showed that the total content of some of the microelements were as follows: Iron > manganese > zinc > lead > nickel > copper. while the chemically extracted microelements content were as follows : - Iron > manganese > zinc > copper > nickel > lead.
