Can anyone think of a good reason NOT to use diluted household ammonia, to raise pH of compost (presently pH 3 to 4) up to a desirable level?
I would expect usage would result in an immediate pH change, compared to waiting on slower lime products. And ammonia should provide nitrogen, as well.
If i remember correctly, farmers once used anhydrous ammonia applied directly to the soil.
As a quick and dirty soltion to low pH it should work ok. It is quickly neutralized so it has little lasting effect if the souce of acidity continies to be present. It is a minor source of nitrogen but has to undergo chemical reaction before it is usable by plants. You did say dilute, so you may or may not kill the organisms that break down your compost.
