Well biochar is a long term game. Its supposed to act like a battery and hold microbes and nutrients and water longer than the soil would. It will pull from the soil til its "full" so you may have to water and fertilize extra at first. Good luck!
That's the plan. I triple dosed the soil with the char so I'm triple dosing it with the black kow and lime. I'm going to give everything a couple of weeks to "settle" before I come back with the trip 13. I don't want to go too far the other way too fast and burn everything up with too much nitrogen plus I want to give that ag lime enough time to break down so it can do it's job with the fertilizer from the black kow. If everything doesn't jump in a few weeks I got the trip 13 on standby.
My goal is get the best yield I can this Summer and then this Fall hopefully the beds will pump out some serious Fall greens. Mama likes kale and I like collards.
