This is the time of year I love to be out collecting leaves. I like to bury my few eggshells, I can dig a hole and bury the eggshells quicker than I can crush them up. I don't get enough to make a noticeable difference so I add dolomite lime when I think I need calcium.I just finished covering my veggie bed with shredded leaves. Each year I do this and each year they just disappear into the soil. The first few years I used a shovel and dug in the leaves, now I just put a layer on top. I let time weather and the worms do their job and it is working pretty well. I also have a slope, but I had no clay in the veggie bed, it drained very well from the start, too well, I could not keep it moist at all. So my method is the same with my clay beds and my non clay beds, but the goal is different. I add compost and mulch to both but with the clay beds I am trying to improve drainage, and with the loamy beds I am trying to improve moisture retention. Thank goodness I have neighbors that don't complain about my compost piles, they just think I am a little strange hauling in leaves when they are trying to haul them off.
