For all living organisms, nitrogen is an essential element, while being the most limiting in
ecosystems and for crop production. Despite the significant contribution of synthetic …

Africa's lands are largely vulnerable and threatened by soil degradation and low water
availability, especially in semi-arid and arid regions, limiting crop and livestock productivity …

Including cover crops within agricultural rotations may increase soil organic carbon (SOC).
However, contradictory findings generated by on-site experiments make it necessary to …

Agroforestry (AF) has the potential to restore degraded lands, provide a broader range of
ecosystem goods and services such as carbon (C) sequestration and high biodiversity, and …

Modern temperate alley-cropping systems combine rows of trees with rows of crops
(agroforestry), which allows for diverse interspecific interactions such as the complementary …

Cover cropping can improve soil C sequestration compared to no cover cropping, but the
mechanism of C sequestration in soil aggregates and minerals needs more exploration. We …

Agroforestry is increasingly viewed as an effective means of maintaining or even increasing
crop and tree productivity under climate change while promoting other ecosystem functions …

Many tropical areas lack soil nitrogen (N), an essential nutrient for plant growth and the
production of food. Commercial N fertilisers are expensive, with only a fraction of this nutrient …

Integration of trees in agroforestry systems can increase the system sustainability compared
to monocultures. The resulting increase in system complexity is likely to affect soil-N cycling …

The nitrogen (N) demand of eucalyptus plantations is considered to be effectively
supplemented by the addition of N‐fixing plants. However, the effects of intercropping …
