What are the long-term effects of different mulches on soil fertility?
I'm deeply interested in understanding how different types of mulch impact soil fertility over time. As a retired botanist, I’ve been using organic materials like wood chips and straw in my garden, which is a blend of native plants and edibles. However, I’m keen on knowing the long-term effects of consistently using specific mulches on soil composition and fertility. Will certain materials deplete nutrients or contribute positively? I’ve tried mixing them, but I’m not sure if I’m seeing the benefits I had anticipated. Can anyone share their insights or experiences on the long-term effects of various mulch types?
