Apparently, the consumer electronics manufacturers made a lot of advances in the recent years. I just got a simple pH meter for food and tested it on six mulberry cultivars. Looks like it works like a charm. I was looking into the complex scientific pH meters for low volumes and those are some expensive pieces of equipment! Apparently, all I needed was a $37 device from our largest online retailer.
The mulberry cultivars I selected for this pilot had contrasting amounts of acidity and the device detected these. Over the season, I hope to measure the pH values across all cultivars we grow.
Below are the data from today. I was lucky to find a couple of fruits of Murray’s Himalayan which I suspected might be the most acidic one. It produced the lowest pH out of these six cultivars.
