Inter-Units Conversion in Soil Analytical Studies

Abstract

This article seeks to provide some inter-unit conversion or provide conversion factor in soil analytical studies. The basis or justification for carrying out soil analysis include the need to know plant available nutrients vis-a-vis their replenishment; to determine increase in crop yield through fertilization; to evaluate the nutrient status of soil and the need for fertilizer application which consequently improve farmers’ decision making for economic planning. Analytical procedures in soil science vary from one method to another, each with its peculiar unit of measurement. The calculation and conversion of units of measurement of different soil parameters will unify conclusions of different analytical results, such as in fertilizer application and experimental reactionary systems. The outcome of this article has provided meaningful inter- unit conversion through simple derivation principles, by the derivation of conversion factors and in practice of fertilizer calculation for fertility studies.
