eighteenth century with the so-called "improved crop rotation" — the summer-sowing of the fallow with clover, and subsequently with root crops (potatoes, beets, etc.). In the course of the intensification of cultivation during the twentieth century, there arose the system of alternating cropping with fifty percent root crops and fifty percent cereal crops. Through the advancing technology and the possibility of steering plant growth almost arbitrarily by means of inputs alien to the farm organism, there arose the systemless, purely market-driven "wild crop rotation."
