>>12667307>BioremediationThis is a robust topic that you may not have any direct need for. Investigate this topic if you find that your land is contaminated or you decide to use a septic leech field for your waste.
>MycofiltrationImproves the water quality of the runoff from your land which decreases the environmental impact of operating a farm. Basically just grow mushroom mycelium from an aggressive mushroom species (like oyster mushrooms), pack it into burlap bags filled with soaked wood chips, then bury them around your fields and line runoff ditches with them.
>Soil amendmentYou may not need to amend your soil, but the topic is still with investigating. I recommend mixing 10% charcoal (by weight) into the top six inches or so of your soil because it allows for better water penetration, increases the CEC, and sequesters a good deal of carbon.
>Biopesticides/herbicidesThese are cheap, effective, and organic (a concept which I detest in practice) which allows you to save money while providing an avenue for organic certification which increases the value of your crops. The easiest method I know of to produce them is to use oyster mushroom mycelium. Pouring cold water through the substrate provides pesticide while boiling the substrate provides herbicides. Use sparingly to avoid pest adaptation.
>Trap cropsThe best way to protect your crops in my opinion. Plant sacrificial crops around the perimeter of your field and inside that perimeter and spaced about 5 ft apart plant another row which gets heavy pesticide treatment. Plant the rest of your crops inside that area spaced another 5 ft from the pesticide row and spot treat any pest infestations that occur in this area.
