Quizás alguien en el entorno del nuevo Ministro de Agricultura sea lo suficientemente generoso como para conseguirlo y leérselo. El Perú no puede seguir el camino al que tercamente nos quiere llevar el fundamentalismo orgánico.
"... Humans have a stark choice to make: do we farm four hectares of land 'organically' to feed 40 souls, or do we farm one hectare 'artificially', thereby leaving the other three to natural woodland and wildlife?
Luis Destefano Beltrán, Ph.D.
The greatest catastrophe that the human race could face this century is not global warming but a global conversion to 'organic' farming — an estimated 2 billion people would perish. That is the underlying message of this remarkable book, which charts the discovery of nitrogen fixation — the conversion of unusable atmospheric nitrogen to useful ammonia — and its impact on the world's food supply.If crops are rotated and the soil is fertilized with compost, animal manure and sewage, thereby returning as much fixed nitrogen as possible to the soil, it is just possible for a hectare of land to feed 10 people — provided they accept a mainly vegetarian diet. Although such farming is almost sustainable, it falls far short of the productivity of land that is fertilized with 'artificial' nitrogen; this can easily support 40 people, and on a varied diet. Of course, 'organic' farming should be encouraged in order to recycle compost and dung. But it can never compete with the bountiful supply of agrochemical nitrogen, which now meets about 40% of the world's dietary needs. Nitrogen is abundant in the atmosphere, but in a form that is difficult to extract; only a few microbes and plants have the capacity to do this. Yet, thanks to their efforts over aeons of time, a whole planetary ecology can now be sustained. This organic nitrogen will even support continued agriculture if properly managed, but it imposes a maximum on the density of the human population.
