Reality #5: To fully precipitate humic acids a soil would have to have much lower pH readings than those we usually refer to as “acid soils”. Non-modified humic acids start to precipitate from pH 3 and lower. We can easily confirm this fact by looking at a simple humate solution. The solution remains stable until it is lowered to a pH level of about 3.0. At that point the humic acids do begin to precipitate into insoluble forms. It is highly unlikely that anyone is growing crops in soils with a pH of 3.0 or less! Therefore precipitation of humic acids during application of humates on soils does not really take place. Again, this is simple science that cannot be disproved.
