Abstract

• Five soil samples were taken from Kalay University campus. Next, five soil samples were grounded with mortar for 1hr and then sieved by a 0.01cm sieve. Then, each sample was weighed 600 grams. To obtain more samples, 100 grams of each from five samples were re-weighed, mixed, and grounded by agate mortar. Finally, a total of six fine soil samples were obtained. Potential Hydrogen (pH) of all soil samples was measured to consider soil acidity or alkalinity. Electrical conductivities of soil samples were tested to investigate the amounts of salts in the soil. Measurements of soil content of Nitrogen(N), Phosphorus(P), and Potassium(K) of two fine samples were analyzed. Energy Dispersive of X-ray Fluorescence (EDXRF) measurements of two fine samples were carried out to determine the elemental contents of soils.
