Leibniz Institute for Agricultural Engineering (ATB), Potsdam-Bornim, Germany, is a European center of agricultural engineering research at the nexus between biological and technical systems. Research targets a knowledge-based bioeconomy. ATB is developing highly innovative and efficient technologies for the use of natural resources in agricultural production systems - from basic research to application. ATB thus contributes to the nutrition of humans and animals, to a sustainable use of biomass, and to protecting of climate and environment.
