" The conventional method would be to stimulate the crop by the addition of factory-made and imported fertilizers such as sulphate of ammonia. There are weighty objections to such a course. [...] Increased crops would indeed be obtained for a few years, but at what a cost -- lowered soil fertility, lowered production, inferior quality, diseases of crops, of animals, and of the population, and finally diseases of the soil itself, such as soil erosion and a desert of alkali land! To place in the hands of the cultivator such a means of temporarily increasing his crops would be more than a mere error of judgement: it would be a crime. "
