Re: Soil conditioner
Black Kow is now 90%+ Silica (sand) the organics leach quickly as they are very fine.
Take 20 lbs, toss it in a five gallon bucket for 20 minutes with water running, you will have ash tray sand in short order.
The best ammendments are top-dress organics. Plants respond to these for many months. Try a quality worm casting, vermi-compost or simply learn to compost and add quality minerals.
If you need to adjust your PH up or down, do so naturally.
Plants, all plants respond far better to a balanced diet than coca-cola synthetics over the long run.
Add some Peat Moss, FE + S and some Sulfur, your water will likely drag it back up, so top dress with 22% Fe + S 9% and this will compensate for 100 days as a leachaette.
Pine bark works very well and has a high carbon / nitrogen ratio. Not the big nuggets, but a ground/coarse mix. You can mix it into the first couple of inches and it will leach over about 18 months. I'd start with 20% and test the PH at increments, your plants will grow much better this way.
Good Luck~!
