Soil compression can be a serious problem, but it isn’t always, or in all ways, a bad thing. For example, impressions made by hoofed animals, so long as they only cover a minor fraction of the soil surface, create spaces in which water can accumulate and help it percolate into the soil more effectively, avoiding erosion runoff.
To meet rising food demands from a growing global population, over 250 million acres of arable land will be needed – about 20% more land than all of Brazil. Alternatively, agricultural production will need to be more productive and more sustainable using our present acreage. Meeting future needs requires investment in alternative practices such as urban and vertical farming as well as existing indoor and covered methods.
