Always plant “complimentary” plants that protect each other from pests so you don’t have to use chemicals to do so. For example, tomato bugs hate marigolds, so get a few cheap marigold plants and put them in the same soil right around your tomatoes.
Diatomaceous earth, the skeletons of plankton. Agitate the ants nest and sprinkle it all over them, might take 2 or 3 applications because it is not a chemical, it is microscopic razor blades that slice up every ant that touches it. Completly safe for humans and animals, some people even drink it.

Use leaf mulch. If you dont have enough leaves in your yard collect people's bagged leaves in the fall. Greatly improves water retention and builds soil quality as it breaks down.
Manure is great, going to provide more nitrogen than just leaves alone. I dont mess with ash, people usually use it to raise the pH of acidic soil and I dont have to worry about that where I live.
What is always super beneficial though is charcoal, before it turns to ash. Charcoal is extremely porous on a microscopic level and provides a good home to beneficial bacteria. Just crush it up fine and mix it into the soil.
If you can get charcoal to 1100 - 1800°F it activates it. Past this temp it absorbency actually decreases. Havn't tried it yet but would give your bacteria even more space to play if it worked.
I wonder if you mixed your ash and manure and left it alone for a few weeks if it would still raise the ph or would the nitrogen fixers neutralize the ash. Your charcoal would probably speed the process up as well.
Edit: I suppose it depends on what you are growing as well. Probably not every plant needs a potassium rich enviroment from the ash
I didnt know charcoal was activated at a certain temperature, I thought it was by adding an acid like lemon juice. I probably wouldnt bother with that process unless I was using it to filter drinking water.
Looks like both ways work. Can also use calcium chloride or zinc chloride. Calcium chloride is cheap and readily available. No idea about the zinc chloride.
