The chitemene system, which creates a surplus of ash in concentrated spaces, raises the soil pH, enabling the cultivation of those crops. Furthermore, the heat generated by the burning of the biomass fumigates the soil, kills any existing weed seeds, and reduces the soil to a fine tilth, reducing labor requirements for cultivation of the soil.
Shifting cultivation is a type of subsistence farming where a plot of land is cultivated for a few years until the crop yield declines due to soil exhaustion and the effects of pests and weeds.
