Perfect response (I believe) is to recommend watching Mendo Dope’s You tube channel https://www.youtube.com/channel/UC8BFOdvurKpz-Y2U4Nroo8g Especially the last year or so. They have began utilizing a cover crop, and organic soil amendments, and its made a world of difference.
What nutrients are you already using if anything? We can try and assist as best as possible with the different background of growers here, based on what nutrients you already have.
I am an advocate for organic no-till. It may cost some money during the transition but save you lots of money in the long haul. Dry amendments like the folks before me have mentioned. I start with Malibu Bu’s blend, malibu compost, and rice hulls and or grow stones. 30/30/30 soil/compost/aeration. If you can get local and trust the source, get local. I would steer away from anything “Supersoil” or that needs to cook. Build a soil craft nutrient blend. I swear by it. And adjust with different ratios of the ingredients accordingly.
Also since its an outdoor crop, don’t forget to research IPM.
