Ultrasonic Characterization on Arginine with Saline Salts(K2SO4, Na2SO4, MgSO4) Solutio n in View to Sustainable Farming

Background/Objective: In irrigated areas, accumulation of salt restricts plant growth, reduces or even stops seed germination, and encourages poor seedling establishment. When the soil's salinity drops, the plants can absorb water and nutrients. A reduction in the growth rate of plants is the initial indication of the plant's response to salinity, which is linked to several metabolic alterations identical to those induced by water stress in plants. This stress significantly impairs crop yield by restricting plant growth. Method: The ultrasonic velocity and density of Arginine in water and 0.2N solutions of Magnesium sulphate, Potassium sulphate, and Sodium sulphate have been measured as a function of concentration at temperatures of 313.15 K and 318.15 K. This fundamental data has been utilized to calculate various thermo-physical parameters of the specified systems. Findings: This study evaluated the impact of Arginine on saline salts, particularly sodium sulphate, magnesium sulphate, and potassium sulphate. The outcome validates the role of Arginine in saline solutions and introduces a novel strategy that improves synthesis through ultrasonic techniques. The degree of interaction is greater for Arginine with magnesium sulphate. It follows that Arginine has greater effectiveness with magnesium sulphate saline solution. It can improve the physical characteristics of saline soil. Novelty: The application of chemical fertilizers adversely affects the physical properties of soil. The application of amino acids in place of harmful fertilizers is sustainable. As a fundamental component of protein, it cannot disrupt the natural balance of soil. The ultrasonic approach is non-destructive, which allows it to determine the type of interaction with greater precision.
