There are industrially manufactured products on the market, so I don't worry much about acidity. I am thinking about adding it to water for my plants in pots indoor, that is at home. I have experimented with dipping the seedlings in lignohumate prior to transplant. Results not known yet. I do have a control group of the same varieties. We'll see what happens.
Unfortunately, manure of any kind is out of the question if I don't want to get a divorce.
In my garden I use manure a lot. I've tried cow and chicken manure and chicken manure seems to be the better option (properly fermented and used) for during-vegetation fertilizing with water and cow manure is better for pre-season patch fertilizing. And horse manure is good for cucumbers.
