This is the pH of the water collected from the shallow detectors.
I was surprised to see how low the pH was - less the 5 in the NaCl plots! The plot irrigated with washing powder started a bit higher (5.7) and increased to 6.5. The washing machine water had a pH of 9.5 .
I studied Agricultural Science and then completed a PhD at the University of Sydney.
I joined CSIRO in 1990 and am currently a Principal Research Scientist based in Canberra working on irrigation, water productivity and the ecological footprint of agriculture.
I also hold an honorary chair in the Faculty of Natural and Agricultural Sciences at the University of Pretoria, South Africa.

Any idea why the pH of the NaCl plot was so low? What was the starting pH of the soil?
