Yemeni soil is generally made up of green deposits, consisting of water and wind erosion, where soil sand is poor in composition or composition.
It is a dry area, and contains a high proportion of lime, and distributed Yemeni soil by natural regions to: –
- The soil of the coastal plains region comprises five types of soils, which are sedimentary sedimentary sediments, which are wind-dispersed soils, tropical dry edifices, rocky soils, sabkhat soil and saline soils.
2 – the soil of the Western Highlands region, and the spread of the rich terraces terraces and the valleys and semi – valleys, and less fertile than the tufts of valleys.
3 – the soil of the region of the central depressions, which are brown mullet, and a dark brown or dark gray structure centered on the bazata rocks, and brown or red brown tubercles to concentrate on limestone rocks and sandstone.
4 – the soil of the province of the inner plateaus and Hadramout plateau, which are light brown tufts that sometimes turn dark under the influence of al-Qa’ida rocks, which are low fertility for the inner plateaus. The soil of the Hadramout plateau is a gypsum composed mainly of calcareous and limestone stones.
5 – the soil of the territory of the internal rocky, and includes soils sandy coarse and gravel and soft and be somewhat fragmented light color infertile, beside the soils of sand dunes. Yemenis are mostly sandy to their baskets in the coastal plains, and their salts are mixed with clay mixtures in mountainous areas.
With low nitrogen, phosphorus and organic matter in most regions. Where erosion occurs in the surface runoff or in the wind, sand storms and dust help to uproot the hills of the plateaus in general.
