Conventional agriculture largely focuses on increasing productivity from a single crop, by plowing top soil, spreading fertilizer, and applying pesticides based on the characteristics of the crop. These practices damage ecosystems and cause other environmental problems. Sony Computer Science Laboratories, Inc. (Sony CSL) is testing applications for synecoculture, a sustainable agricultural practice that balances productivity with the need to reduce environmental impact. Synecoculture eliminates the need for plowing, fertilizing, and pesticide use that impact the environment, by taking maximum advantage of the material cycling that occurs naturally in ecosystems, aiming to create rich ecosystems with a diverse mix of plants that coexist together. Synecoculture requires vast knowledge of plant ecology, and for several years Sony CSL has been conducting tests at a number of farms, cultivating a blend of plants in order to collect data on plant compatibility and soil conditions. Sony is also using original IT tools to develop a synecoculture support system based on the test data.
