DIY ph testing....is it worth it ??
I'm a container tomato hobbyist and retired Mechanical Engineer. I'm fascinated by the extensive highly technical discussions on plant biology, chemistry, soil mechanics, etc. I find it amazing that anyone can ever grow a successful plant given every thing that can go wrong.How did the Mesoamericans do it without the benefit of Forums, Al, Dave, et. al.( Bless them)?
Is it worth the effort for a hobbyist who doesn't want to invest in lab quality equipment to even bother with the DIY single test kits or low end (cheap)meters? Given the dynamic nature of soil ph, macro and micro nutrient levels, etc. sending a sample out to A&M seems futile.
Any thoughts would be welcome.
