TL;DR: The Nutrient Use in Animal and Cropping systems -Efficiencies and Scales (NUANCES) framework as mentioned in this paper offers a structured approach to unravel and understand the complexity of African farming to identify what we term "best-fit" technologies, targeted to specific types of farmers and to specific niches within their farms.

TL;DR: In this article, the authors review responses to simulated N deposition from nine experimental sites across the UK in a diversity of heathland, grassland, bog and dune ecosystems which include studies with a high level of realism and where many are also the longest running globally on their ecosystem type.

TL;DR: In this article, the authors identified five representative farm types using socioeconomic information and considering production activities, household objectives and the main constraints faced by farmers, and related to differences in soil fertility status at farm scale.

TL;DR: In this article, the authors identify critical steps where efficiency of nitrogen cycling through livestock in smallholder crop-livestock farming systems could be increased, with special emphasis on Africa, by conceptualizing farming systems in four sub-systems through which nutrient transfer takes place: (1) livestock: animals partition dietary intake into growth and milk production, faeces and urine; (2) manure collection and handling: housing and management determine what proportion of the animal excreta may be collected; manure storage: manure can be composted with or without addition of plant materials and (
