A perfect soil would be such a blend of sand, clay, chalk and humus as would contain sufficient clay and humus to prevent drought, enough sand to render it pervious to fresh air and prevent waterlogging, chalk enough to correct the tendency to acidity of the humus present, and would have within it various substances which would serve as food-materials to the crops.
Transgenic approaches would be useful to deal with problems related to stem borer, leaf blight, and sensitivity to waterlogging in corn.
To guard against frost damage they are fired to 1160 degrees centigrade yet remain porous allowing roots to breathe and preventing waterlogging.
