In what way am I twisting any of your words? You say “chloramine crushes fungal population”. You do realize that nobody is pouring undiluted industrial strength chloramine onto their plants, right?
People water their plants with tap water. The municipality that delivers the tap water treats it with chloramine. According to the water quality report of the municipality where I live, the maximum allowable concentration of chloramine is 4 ppm. I’m not sure if that maximum is set nationally by the EPA or if it’s determined at the state level. In either case, the average amount actually present in the water is 2.1 ppm, according to their report. Chloramine, at the levels actually present in the water that people use, is the only form that has any relevance to the discussion. My experience (and that of many others) is that any effect on beneficial microbes and fungi in the context of growing little trees in pots is negligible.
If chloramine, at the levels delivered in municipal tap water, actually “crushes fungal population” as you claim, then why are my Japanese white pines, Japanese black pines, ponderosa pines, red pines, etc. thriving despite being watered regularly with chloraminated water? It’s well known that pines are heavily dependent on mycorrhizae to extract nutrients from the soil. If my fungal population is crushed, why aren’t my pines dying?
