Abstract

Experts and researchers in soil, plant and water science seek to understand the nature of the relationship between soil salinity and its effect on its acidity. Each plant has a tolerance range of salt and an ideal acidity level to live and grow in. 5 irrigation water samples were taken from 5 random sources in Zarqa, Jordan, in 2018 and 2019, where salinity and acidity were measured using specialized electronic probes. The regression and correlation analysis showed a weak dependency of irrigation water pH on total dissolved salts (TDS) to the point that it is a positively negligible relationship. The study recommends taking a large and random number of soil and irrigation water samples to confirm or deny this scientific observation.
