| To increase nutrient use efficiency and reduce nutrient losses are key aspects for sustainable agriculture. Arbuscular mycorrhizal fungi (AMF) are an import and widespread group of plant-symbiotic soil fungi. Here we investigate the role of those soil microorganisms, for effective nutrient recycling. We conducted greenhouse and lysimeter experiments to compare the cycling of important plant nutrients in systems with high and low abundance of AMF. AMF increased plant N nutrition, reduced leaching losses of mineral N, and prevented emissions of N2O, an important greenhouse gas. The results show the importance of AMF for an effective nutrient management. Farmers should implement strategies to promote AMF in the soil, as they are an indispensable compound of... |

| Grass-clover pastures form an essential part of organic farming systems. It is well known that nitrogen fixing bacteria play a key role in determining productivity of grass-clover pastures. Yet, the impact of other plant symbionts, such as arbuscular mycorrhizal (AM) fungi, on grass-clover is still poorly understood. Here we demonstrate that AM fungi enhanced red clover biomass and enabled red clover to coexist with grass. Moreover, the diversity of AM fungi in the soil promoted productivity of grass-clover mixtures. Inoculation experiments in a range of field soils with native AM fungi showed that addition of AM fungi promoted clover biomass in several (but not all) soils. This study shows that AM fungi can be important for clover establishment in pastures. |
