I had the idea to use nettles is the same way rather than making tea. What is the difference between 1.)nettle tea the traditional way 2.) aerated nettle tea 3)directly mulching nettles.
Another plant I might play with it borage and yarrow.
Compost teas are used to feed plant leaves, not soil. Compost extracts (more concentrated than tea) is used to feed soil.
The whole idea is to beef up the organism numbers in your soil, thus allowing the soil to feed the plants as it is supposed to.
If you are mulching with nettle and other plant material, some of the good things in those materials is going to end up in the atmosphere instead of in the soil, plus you are not growing any new organisms to add to your soil.
It is very rare to find any soil that has enough organisms of the microbiome needed for great plant growth, thus we brew aerated compost teas and extracts, which will grow the organisms and we then deposit these in the soil when we water the plants with our extracts or teas.
The only real difference using an extract over a tea to water a plant is the quantity of organisms (bacteria, fungi, amoeba, flagellates, beneficial nematodes, etc.) will be higher in a properly brewed extract compared to a properly brewed tea.
Many people don't use teas or extracts but instead use large quantities of well made compost, they get similar results. The extracts and teas are just a way to stretch the amount of compost you have.
If you have lots of compost, use it, if you don't, then a tea or extract might get you more bang for your buck (efforts).
Comfrey, borage, nettle are all great compost materials, thus they are good to use as mulch too, you just won't get any addition to your microbiome in your soil for a long time.
