Determination of Some Physical Properties and Electrical Conductivity of Loamy Soil with Additives

In this study, the electrical conductivity and physical properties of loamy soil samples with various additives is determined. The electrical conductivity meter was used to obtain the electrical conductivity and some standard methods have been adopted to obtain other properties. It is observed that the soil combined with NPK had the highest electrical conductivity with the least coming from the soil (control). It is concluded that NPK raises the electrical conductivity of the soil. This goes forth to show a measure of the amount of salts in soil (salinity of soil), which is an important indicator of soil health. It affects crop yields, crop suitability, plant nutrient availability, and activity of soil microorganisms which in turn influences key soil processes including the emission of greenhouse gases such as nitrogen oxides, methane, and carbon dioxide. It is recommended that soil with organic manure should be used in order to maintain low salinity and good soil health.
