Environmental analysis of crop rotations through the application of the Cereal Unit approach

The sustainability of agricultural practices is a key element for an effective implementation of the UN’s Sustainable Development Goals, particularly relating to ending poverty and hunger, responding to climate change and supporting the natural resources. As part of ongoing research and improvement...
