Weeds

Hi, I'm working on a monoculture orchard that I'd like to transform into a poly culture orchard. The soil is very compacted and in some area there are weeds. I'm looking into emending the soil fertility and favor de compaction through planting of daikon and nitrogen fixing cover crop. Any suggestion on how to get rid of the weeds to make room for my em ending crops? No lasagna, it's a huge orchard and it would defeat the idea of solving compactation.

Can you mow them? Depending on what kind of weeds they are, moving them several times fairly close together before you plant your cover crops may sap their vitality enough to give your cover plants a fair start.

Depending on what the weeds are, they may already be doing your decompaction work for you. Mullein puts down a good sized taproot, as do dandelions.
"Weeds" is a very vague word, especially around this crowd, where one man's weed is another man's dinner, or dynamic accumulator and chop and drop fertilizer, and so on. Some of those weeds may also be helpful for attracting pollinators, a valuable asset in an orchard setting.
