it does,,with my water,,i have a 500 ft well,,thing is the nearest damn is about 50 miles away,,got me one of the pool test kits,,500 ppm,damn and no boron count at all,,so im thinking along the line of 3 55 gal plastic barrels daisy chained together with a pump in one to pump down hill to garden,,treat the water with vit c and go with that,,when i do water i use a lot,,just about everything i plant require a inch of water weekly,,the asorbic acid is great to get ride of clorine so i want to see how it works with garden,,i used just the tap this year and didnt see any effects at all so buffering does take place,,but had hardly no yield at all from the garden,,beautiful plants,just lacked yield,,now that could have been from the soil which after soil test showed me it lacked a lot of things,,ive redone all the boxs and soil and going to wait a month now and send in another test to see were im at,,thats the main reason im doing the test,,if soil is right to start,,then poor production is on me no questions asked if you dig,,the alkaline water i dont think is a big problem just like you said buffering,,but main idea behind the daisy chain barrels are mainly to send tea down threw the soaker hoses,,thats a lot of 5 gal buckets going up and down that hill for a old fart lmao
