An Acoustical Study to Explore Agriculture Nutrient Management Strategy in View to Enrich Soil Fertility

Abstract

The present manuscript reports the ultrasonic characterization of Potassium Sulfate (PS): fertilizer at varying concentrations from 0.02-0.2 mol-kg-1 in water and also in 0.5 mol-kg-1 aqueous soil salt solutions at 303.15 K temperature. Ultrasonic velocity (U) and density (ρ) measurements were carried out by a 2MHz frequency interferometer at a fixed 303.15 K temperature respectively. Using obtained experimental values, various acoustical and volumetric parameters have been estimated using standard relations. The volumetric and acoustical studies clarify the nature of interaction that exists in binary as well as ternary liquid solutions. The variation in ultrasonic velocity and other parameters plays a significant role in understanding the solute-solute and solute-solvent interactions between the constituent molecules. These studies lead to a better understanding of Potassium Sulfate (PS) and have application in pure and applied research in the field of agriculture in view to increase the fertility of the soil or to counteract the problem of soil salinity. Therefore, the proposed study is worthwhile and interesting in many aspects.
