Ensuring a Productive Fall Harvest

I'm a first-time organic gardener and am now picking some of my first summer veggies. I would like to plant some veggies for the fall, but was wondering what I should do in terms of fertilizer or mulching to ensure a good harvest.

Any tips will surely be helpful.

Thanks,
Zym

What are you planting?

Take a soil test. Amend accordingly. If you're too acidic / compact , lime your area, or use gypsum.

If you'd like to try a lil 'soil creating' I'll always suggest sheet mulching a few new areas on your property. What sorta space are you working with?

Here's a small one for example, at a rental property earlier this year:

Here's a larger one, for my friend:

Provide a base layer, find/source tons of clean (no herbicide,toxins) organic matter. Brown leaves, grass clippings (excellent nitrogen source), worm castings, finished compost, manure, old straw (bales that have sat for months/years), rock dust (minerals), river sand, finely-grated hardwood chips.

Below is a fairly current photo of his area, just to give you an idea how sweet (nutrient-wise) this configuration can be...
