Hey guys. Just thought I'd pop in and share what I'm working on right now....
My organic runs have been going great, but the one thing I'm noticing is a bit of an early fade. I suspect that this is due to a lot of my organic inputs being leached out of the soil when I water. I think that's the case anyway. To combat this, I have been looking in to something Rrog has turned me on to. Biochar.
In layman's terms, biochar acts and as nutrient storage device of sorts. Due to it's high porosity, it is able to store organic nutrients (that won't be leached out of the soil), and in the presence of microbes in the soil becomes bio available to the plant at various stages of it's development.
Making your own biochar looks to be a daunting task, so in lieu of being that handy (which I am not), you can pick up a bag of *all natural* charcoal such as Cowboy brand. You want to break this up in to small pieces (around 1/2 inch in diameter) and then activate the biochar. This is a crucial step. If you don't activate it, it can have the opposite effect in your soil by stealing the organic nutrients out of your soil and depriving the plant. There are several ways to activate the biochar which include a bokashi method, or by adding it to a compost pile. I chose a third, quicker option. I have taken some alfalfa meal, kelp meal, and some Espoma Garden tone (in large part because it includes beneficial microbes) and bubble this mix in a few gallons of water for 24 hours. Over the course of a couple days you will soak the biochar in this nutrient solution, allowing it to completely absorb this organic, nutrient rich liquid.
At this point your biochar is now charged, and ready to be added to your soil mix. I e-mailed Rrog, and am waiting to hear back from him on how much of this activated biochar is to be added per cf of soil ..... and if the soil should be left to further inoculate before placing a cutting in it.
I feel pretty confident that this will address my early fade issue, and give my ladies everything they need throughout their life cycle. I will update this post once Rrog gets back to me.
edit: Per Rrog, 3-4 cups of charged biochar is added per cubic feet of soil.
