Abstract

It has been demonstrated that the potassium rich rocks and/ or minerals contain potassium ions in the form of K20 most of it are able to be released. Therefore the main objective of this research is to study the chemical and mineral constitutes of three sediments from: Rod Ishab, Umm Kheiam and Wadi El Gemal in the Eastern Desert of Egypt. The obtained results indicate that the soluble and exchangeable forms of potassium are quite sufficient for plant growth. The detailed petrographic examination of the thin sections under the polarizing microscope indicated the dominance of feldspar groups (microdine, orthodase and plagioclase) with some quartz and micas. These minerals show cleavage and cracks due to alteration and weathering In different degrees. The total K content, originated mainly from orthoclase and microdine KAISi3 that dominate in the studied deposits, Is found in considerable proportions (6.96 - 8.60 % K20). The mobilization of potassium from these potassium rich rods can occur through grinding and mixing with organic materials. The recommended application can substitute partly or completely the chemical fertilizers (e.g. K2S0.) which is rather expensive and easily soluble and can be lost through drainage.
