The objective of the study is to measure the ultrasonic velocity, density, and viscosity of the plant-growing media prepared with different combinations of soil texture and moisture absorbent growing media. Four groups of soil texture (S1: loamy; S2: clay; S3: sand; and S4: pure sand/quartz) along with five moisture absorbent growing media (G1: coco peat; G2: vermiculite; G3: vermicompost; G4: sawdust; G5: hydrogel; and G6: control—soil alone) were used. Results showed that these acoustic detection technologies showed significant difference in soil physical properties. Ultrasonic studies described the nonlinear variations in the acoustical parameters among the different soil texture types and growing media tested. Moreover, the values of the acoustical parameters indicated the soil texture when added with any of the moisture absorbent media; water-holding properties of the soils are significantly varied and it suggests that even sand with less water-holding property can be used as a plant-growing medium, with the support of any of these moisture absorbent media (especially hydrogel). The lowest velocity was observed in pure sand alone. However, as the plasticity and the clay content of the soil increases, the porosity also increases and resulting in a decrease in the densities and increase in water content of the soil. Similarly, in heavy-textured soils (high clay content), addition of moisture absorbent media was negative. The comparative study of acoustical properties was made to elucidate the inter-ionic interactions in solutions of soil texture, and growing media and which help to choose the right combination of soil texture and moisture absorbent growing media. The results confirmed that the ultrasonic technique was a powerful and effective tool to investigate the molecular interaction between soil texture and moisture absorbent growing media and helpful for irrigation management.
