Article Title: Engineering Properties of NPK Fertilizer Modified Soil
by Ezeokonkwo, J. C

NPK fertilizer is applied to the soil to modify its properties to give greater crop yield. These soil properties include: unit weight, void ratio, water content, and plasticity, tensile strength, compressibility, permeability and compact ability. Thus it becomes imperative to examine the engineering properties of NPK 20-10-5 fertilizer modified soils. Analysis of test results showed that the liquid limit, shrinkage limit, coefficient of permeability, and void ratio are decreased by the addition of fertilizer. It reduces the shear strength parameters of a soil. Therefore, NPK 20-10-5 fertilizer decreases the bearing capacity of soil and thereby increasing its erodibility
Keywords: NPK fertilizer, soil, stabilization, plasticity, permeability, shear strength
