i started out thinking that i needed to develop the gene pools and methods to farm in a sustainable way, without the ability to move around to replenish rotational grounds, without the importation of resources such as soils, fertilizers, and most importantly, water. when i have more area set aside for wildlife restoration and native plant reintroduction, and i am keeping the area free of most woody species, then i get alot of tall grasses, weeds, invasives and whatnot to use as mulch. the same soil the crops are grown in is what the weeds compete in so the weeds that are designed to accumulate what the soil in my crops' hills lack decompose releasing those minerals and nutrients. this reduces the need for rotation. also a perennial polyculture is maintained around the circumference of every hill, making soil retention and microbe/insect habitat ideal for fertility and disease/pest suppression. the mulch assists with the issue of no irrigation as the increase of biomass holds more water, the light cellulose barrier at the top, instead of a dense soil exposed, traps water and deflects heat. the mulch also breaks down slowly to feed the soil at the rate at which is can be fed, rather than force feeding, or starving. as a soil learns to take more, it is capable of giving more, and vice versa. it is important to have thick mulch, but not so thick as to create compost like conditions as this would be the wrong kinds of decomposer cultures for healthy root systems. without tilling, the soil needs to be free of compaction forever more, so walking on the hills is a sin. as the years progress and biomass accumulates the hill grows, and the soil loosens deeper and deeper. the plume of microscopic and macroscopic biological activity from the mulch sinks into the earth creating passageways for the water, air and roots, even in hard clay soils. the dark skin of the top is highly active eating away the mulch. as the mulch is broken down, the proteins release their nitrogen as ammonias and feed the plants. when the hard clay is tilled it destroys this cycle, and the digestive system of the soil. in order to fit the most planting space together with consideration of walkways, i instantly think back to traditional hill patterns of my ancestors. the same as the beehive, or the seal of solomon. with seven hills as close together as possible you get a hexagon. i put my feet apart to see how far i can spread them to be able to reach the center, and i have my standard measurement for how big i make them. i have 3 main methods of preparing soil for planting, mulching heavily and coming back to a weed free, insect loosened soil to plant the following year is the easiest way to plant and i do that for most things, but for my hills i do that too, only starting out with a shovel only the one time to turn the sod and shape the hill. i turn the soil once to get the sod flat and even upside down, then i rake the soil into a mound and then i mulch heavily. i try to do this early in the year right as its being planted so the broken soil that is releasing a nitrogen bomb will feed the first generation, and they will trap some of that fertility for the next year. at this point there is little that will grow back and you will be effectively weed free. just keep up with the mulching. at the end of the crops lives, the mulch is the thinnest from age, and i cut the plants at the base, lay them flat, and then lay a thick layer of the mulch of grasses and weeds on top. becuase i grow a high diversity of crops (when the animal deterrents work) this also reduces the need for rotation. becuase the diversity is planned it is even more effective still. the ideal thing would be for the pioneer crops you grow to produce more biomass than the pioneer weeds that would replace them if your hill was abandoned, as to continue increasing the fertility for next year. the growth of plants does not deplete soils as 2% of the plant is produced from the soil, the rest is from air, water and alchemy. its when we break the soil that the carbon breaks from the nitrogen, causing erosion on a chemical level, called mineralization of the humus.
