The yield of agricultural production is highly determined by soil quality. Plants, just like other living beings, need food for their growth, development and reproduction (Njoyim et al., 2016a). The challenge for agriculture in the world today is to meet the world’s increasing demand for food in a sustainable way and declining soil fertility and mismanagement of plant nutrients have made this task more difficult (Yerima and Van Ranst, 2005; Yaser and Rahim, 2013). A soil is known to be rich for agriculture depending on its nutrient content, amongst other physico-chemical factors such as soil pH. Thus, assessing the quality of soils (nutrient content) used for agricultural production is paramount for the maintenance of optimum growth conditions needed by plants for maximum yields (Njoyim et al., 2016a). Soil degradation is widely recognized as major agricultural and environmental problem (Ruqia et al., 2015; Njoyim et al., 2016b). There is tremendous need for greater understanding of Cameroonian soils, and to develop management options to help increase agricultural productivity while nurturing soil health and preventing water pollution. The problem of farmland contamination by heavy metals has raised serious concerns for emerging countries such as Cameroon (Njoyim et al., 2016c). Soil chemistry distinguishes heavy metals as a special group of elements because of their toxic effect exerted on plants upon their high concentrations (Vodyanitskii, 2016). Depletion of plant nutrients in the soil is a major problem in the Awing community where most of the inhabitants depend so much on agricultural production for their livelihood. Human induced processes such as industrial establishment, mining, agriculture and transportation, release high amounts of heavy metals into soils, surface and ground water and ORIGINAL RESEARCH ARTICLE
