By 2050, agriculture needs to provide food and energy for 9 billion people. At the same time, agriculture is losing huge areas due to soil degradation. Within the UN sustainable development goals, land degradation neutrality indicates a key element to face this challenge. We propose a cropping system that aims to increase soil fertility of degraded and marginal sites and increases their potential for biomass production. For improved agricultural practice on degraded and marginal soils, we combine perennial biomass crops, legume intercropping and organic fertilisation. Following the idea of a closed nutrient loop, we do not only reapply nutrients but also use the carbon share of the organic fertilisation as a soil amendment, increasing soil fertility over time, allowing sustainable plant biomass production.
