I want to discuss in this thread essential soil amendments for guerrillas. Obviously each person's needs will be different depending on their native soil and environment, but what most guerrillas have in common is that they can't logistically haul large amounts of heavy soil into where they'll be growing, and so they've got to haul in amendments to make their native soil as suitable as they can.
Like many others, the native soil I'm working with has lots of clay -- a mattock makes digging through this and breaking it up much easier than using a shovel. Because of my environment, I also can't use any animal-based amendments (no blood, bone, or fish) because critters and large animals alike will come and dig the soil & plants up.
Here are my main amendments that I'm planning on rolling with this year:
-Pulverized lime (raise calcium and quickly adjust ph)
-Local compost (nothing blood, bone, or fish, but manure is cool. Can't make my own this time around, any particular recommendations on what specifically I should use? I'm curious about mushroom compost, but I'll probably go with good old cow or chicken shit. I may also topdress with bat guano before flowering)
-Insect frass 2-2-2 (great source of all sorts of micronutrients as well as chitin, which is perhaps even more important because it gets the plant's SAR going to help fend off insects and disease)
-Rice hulls/lava rock/sand (whichever I can get cheaper) for aeration.
-Gypsum ( *if necessary* to increase calcium and break up the clay).
I'm probably going to go a little light on the compost for logistical reasons, and heavier on the insect frass because it's very light in comparison. Aside from compost, all of these amendments are pretty light.
Am I missing anything essential?
