Physical, chemical and mineralogical characteristics of some selected gardud soils of kordofan region

Abstract

Recently much of the attention is given to gardud soil as the main alternative for the depleted marginal sandy soils. A lack of exact knowledge regarding these soils are evident. For studying gardud soil four sites were chosen according to the annual rainfall. Two pits were excavated in each site to represent the concaved and convexed locations plus composite samples to cover the area between two pits. Morphological, physical, chemical and mineralogical investigations were made. The results showed that the gardud soils were relatively differed within and between sites due to the climate and the topography. The dominant clay minerals are kaolinite, montmorillonite and illte. The chemical and physical characteristics were poor. Some of the restrictions limiting the use of these soils such as erosion, hardness, fertility, stoniness, drought and acidity. According to the American system of soil classification, the soils studied were given the following classification: (1) Bardab soil: (A) Kanhablic rhodustalf-fine clay, kaolinite, isohyperthermic (concaved). (B) Kandic paleustalf-very fine clay, kaolinite, isohyperthermic (convexed). (2) Sodari: (A) Typic comborthid-coarse loamy, mixed hyperthermic (concave). (B) Typic comborthid-coarse loamy, mixed hyperthermic (convexed). (3) Nihud (Rahad Elsilk): (A) Rhodic paleustalf-fine loamy, kaolinite isohyperthermic (concaved). (B) Aridic paleustalf-fine loamy kaolinite isohyperthermic (convexed). (4)  More>>
