Here's a pic of what used to be heavy clay, hard as a rock when dry! Sticky ass shit when wet greasy id say .. if I'd to take a shovel to this now wet or dry I could sink it easily 10" deep with no effort, REDS have been working it also for the last three years or so, this pic is a 6-7 inch trowel the clay on the bottom you can see just crumbles. aggregate in nature almost like cottage cheese!
I throw straw and fall leaves on it every year to keep the worms happy and fed!
I could dig a foot deep hole with a soup spoon! I'm very proud on how I'v turned the shit soil a complete 180!
