Analysis on Selected Physical Properties in Soil Sample of Modibbo Adama University, Yola, Nigeria

Abstract

Soil is a natural body consisting of layers (soil horizons) of mineral constituents of variable thicknesses, which differ from the parent materials in their morphological, physical, chemical and biological properties. Soil testing is the only way to determine the availability of moisture, texture, pH, and nutrient status in soil. Results of physical and chemical tests provide information about the capacity of soil to supply mineral nutrients. Soils in the garden may have been deposited some thousands of years ago by volcanoes, glaciers, floods, or other processes or were delivered to the site by truck or other mechanical device, but little or no research was carried out (no documents) to determine and ascertain the soil properties or nutrient elements found in the area. The aim of the study is to analyse some selected physical elements from soil samples obtained in the botanical garden of Department of Plant Science with objectives as to determine soil texture, moisture and pH of samples in the area. Results in the physical analysis of selected soil samples showed that the soil sample with highest amount in percentage in soil texture is clay soil with 60%, followed by silt with 21% and sandy with 19% respectively. Furthermore; the analysis revealed soil moisture (0.998%) and pH is neither acidic no alkaline i. e neutral (7.10) and this type of soil pH indicates the ability of a soil to favour some agricultural practices. It is concluded from the results obtained that soils in the area are composed of clay (60%), silt (21%) and sandy (19%) which are good for few crop’s cultivation but can be better by addition of organic and (or) inorganic fertilizers. It is recommended to amend the area with organic fertilizers as they are biodegradable and don’t cause harm to humans as well as the environment.
