Figure 4.3 Dry and Wet Season Soil Sampling Points Note: Two of the locations sampled during the wet season were a considerable distance from the Project site (2.6 km) and therefore are not shown
4.5.1 Soil Types 4.5.2 Soil Quality The key soil types in Nigeria, as identified by the Food and Agriculture Organisation (FAO) soil taxonomy legends are fluvisols, regosols, gleysols, acrisols, ferrasols, alisols, lixisols, cambisols, luvisols, nitosols, arenosols and vertisols (FAO, 2009). Within <strong>Edo</strong> State the soil type is chiefly a red-yellow ferrasol on loose sandy sediments. Research from the neighbouring LGA of Esan also illustrates ferrasol soils ranging in colour between red-brown in the north of the region, to yellow-brown in the south, demonstrating a variation in the leaching of the soil (yellow-brown soils indicate a higher level of leaching). (Omofonmwan and Kadiri, 2007). More specifically, Benin City is underlain by sedimentary formation of top reddish clayey sand capping highly porous freshwater –bearing loose pebbly sands, and sandstone with local thin clays and shale interbeds which are considered to be of braided stream origin. Sands, sandstones and clays vary in colour from reddish brown to pinkish yellow on weathered surfaces to white in the deeper fresh surfaces. Limonitic coatings are responsible for the brown reddish-yellowish colour. The Study Area falls into the southern belt of forest soils. The soil types within the forest soils zone are largely determined by the parent rock. The soil type on the site is a mixture of sand, silt and clay with a predominance of sand and hence can be defined as sandy loam (Royal Horticultural Society, 2011 and NIPP, 2010). The percent composition of silt and clay did however vary considerably between seasons (<strong>Environmental</strong> Accord Limited Nigeria, 2011). The soils sampled were predominantly friable in nature during the dry season, with evidently higher moisture content during the wet season. Soils were found to be fine grained with soil colour ranging between a reddish and dark brown. Soils were lighter in colour to the south of the Project site (southern portion) indicating poorer soils with less organic matter and a lower nutrient content. Northern Portion Heavy Metal Composition. All heavy metals corresponded to levels that naturally occur in soils (Allen, 1974) and fell within the limits tolerated by plants and organisms indicating the low levels of pollution in the soil. The highest concentration of heavy metals analysed across the Study Area during the dry and wet season was iron, which was higher in the topsoil (864.10 – 20,000 mg/kg) compared with soil sampled at 15 – 30 cm depth (656.20 – 18,500 mg/kg). Nickel had the second highest concentration sampled during the dry season (4.6000 - 10.150 in the topsoil and 5.6000 – 17.050 mg/kg in the subsoil). The levels of nickel were less than 0.050000 mg/kg at all points sampled during the wet season. Chromium recorded the second highest AZURA EDO IPP 4-8 DRAFT EIA REPORT
