Introduction
Long-term field experiments are a valuable research infrastructure to provide information about plant × environment interaction and nutrient use. The ‘Eternal Rye’ trial at the University of Halle-Wittenberg, Germany, was established by Julius Kühn in 1878 and is the world’s second oldest long-term fertilization trial. During the long history of the trial, the rye varieties...
- Introduction
Potato farmers are easily tempted to apply high N rates (Vos, 1999). This runs counter to an increasing interest in society to use nitrogen (N) fertiliser efficiently. The conventional fertiliser strategy for potatoes in The Netherlands is a single basal N application shortly before or after planting. Sidedress or split N application has been proposed as an alternative...

Despite the significant improvements in wheat productivity achieved through breeding progress over the past few decades, there remains a pressing need to target even higher yields to fulfil the growing global demand for food. Understanding the response of both historical and modern wheat cultivars to various management strategies is crucial. This understanding can assist in...
1. Introduction
Crop phosphorus (P) nutrition is one of the key sustainability challenges of the 21st Century (Cordell and White, 2014). Crop models are pertinent tools to study and manage phosphorus in agro-ecosystems. However, P modelling is suffering a delay as compared to nitrogen and carbon. A major reason of this delay is the difficulty in formalizing a semi-mechanistic model...
Thinopyrum intermedium subsp. intermedium is currently proposed as a perennial grain crop. This crop is multifunctional by providing grain for human consumption, forage for livestock and multiples ecosystem services thanks to its year-round soil cover and its extensive root system. In comparison to annual crops, Th. intermedium prevents nutrient leaching (Jungers et al., 2019) or enhances soil...
Introduction
Climate change and other societal targets require strategic decisions in agriculture, at different levels of organisation and spatial context. Process-based simulations models support such decisions by making relevant processes graspable to the stakeholders that formulate a large range of different questions. Many of those questions require model simulations in a larger spatial...
