GM soybeans and coexistence.

Genetically modified soybean varieties with resistance to the herbicide Roundup have obvious effects on the economics of production. Acceptance by farmers, therefore, was very rapid, and global adoption rate for RR soybeans in 2011 was 75% of total soybean acreage. Such a rapid rate of adoption was partially caused by genetic contamination of fields, machinery, transportation and storage units with conventional soybean. That, and concerns about disturbances in the environment through deforestation, soil degradation, pesticide pollution, genetic contamination, and occurrence of herbicide tolerant weeds are the strongest arguments for the rejection of genetically engineered plants and animals. Therefore, the possibility of the coexistence of growing biotech, non-biotech and organic crops has been subject of numerous investigations, studies, workshops and seminars. This topic is of great importance not only for farmers, agronomists, and scientists that are directly involved into it, but also for government legislative offices, as well as the community at large. So far, the coexistence of growing biotech, non-biotech and organic crops proved to be very difficult in spite of laws, regulations, and technical guidelines on the matter, and possibility of integrating different production systems is yet to be seen.
