Reply #4: Genetic modification actually cuts the productivity of crops

Genetic modification actually cuts the productivity of crops, an authoritative new study shows, undermining repeated claims that a switch to the controversial technology is needed to solve the growing world food crisis.

The study - carried out over the past three years at the University of Kansas in the US grain belt - has found that GM soya produces about 10 per cent less food than its conventional equivalent, contradicting assertions by advocates of the technology that it increases yields.

Professor Barney Gordon grew a Monsanto GM soybean and an almost identical conventional variety in the same field. The modified crop produced only 70 bushels of grain per acre, compared with 77 bushels from the non-GM one.

The GM crop - engineered to resist Monsanto’s own weedkiller, Roundup - recovered only when he added extra manganese, leading to suggestions that the modification hindered the crop’s take-up of the essential element from the soil. Even with the addition it brought the GM soya’s yield to equal that of the conventional one, rather than surpassing it.

This little setback won't stop Monsanto/ADM/Cargill etc. from trying to lock up the world's food supply, though.
