A new way of farming became at hand when “Roundup-resistant” soybeans were achieved. Roundup is a herbicide that is toxic to invasive growing weeds, but not to animals or people. The most preeminent component in Roundup is glyphosate. In the early 1990’s scientists managed to give the soybean plant resistance to glyphosate so that Roundup would have no effect whatsoever on these plants. Their seeds even yield Roundup-resistant plants.
Therefore, farmers no longer need to mix herbicide cocktails but simply spray Roundup whenever weeds appeared so, from reduced farming, which at that time was the most advanced technique (conventional farming using a plowshare and a moldboard plow was the predominant activity), alternating between years of crops and years of pastures and the production of traditional crops such as wheat and sunflower, the company managed to pass to continuous agriculture with direct seeding, incorporating soybean and its double crop with wheat and technologies to obtain high crop yields, based on nutrition, genetics and crop protection.
