TITLE STORY AGRICULTURAL CHECKERBOARD 9 12 13 15 ZALF researchers are testing the hypothesis if smaller and more diverse fields are able to conserve natural resources, protect soil fertility, reduce pesticide and fertilizer application, and promote biodiversity. In a unique landscape experiment, they are now testing their hypothesis under on-farm conditions. What are the effects of growing several crops like maize, lupine and sunflower right next to each other in smaller field units? Can a farm be profitable under those conditions? And which role will new technologies like robots and artificial intelligence have to play?
