Overview

Introductory CAPRI Training Session and GAMS Tutorial Announcement We are thrilled to announce that this year's Introductory CAPRI Training Session will take place from 23 to 26 September 2024. In addition, we are offering a voluntary GAMS tutorial for those with no prior experience with the GAMS modeling language, scheduled from 27 to 30 August 2024. To participate in the course, please register here. Please note that completing a self-study tutorial is a prerequisite for participating in the course. We look forward to your participation!

CAPRI Developer Meeting 2024 The Capri Developer Meeting 2024 will take place on the 27th-28th February in Berlin (on the Campus Nord of the Humboldt University; Hannoversche Straße 27, 10115 Berlin. Haus 12. (Room 2.01)). For further information please contact: davide.pignotti@thuenen.de. The aim of the CAPRI Advanced Training Session (Developer Meeting) is to organize knowledge transfer between developers, experienced users and other participants in the form of presentations on various new developments in CAPRI. Participants will be informed about the relevance, underlying theory, data and technical implementation and will have the opportunity to discuss the new modules. Here you can find the agenda.

GAMS pre-course as part of the CAPRI online Training Session 2023 successfully completed!!! The GAMS beginners course took place from 6th-8th September. In three days, 15-20 participants learned the basics of the mathematical programming language GAMS and how it can be used to describe the supply side of CAPRI using a didactic model.

Agricultural land use and environmental indicators at 1x1 km grid resolution- Nitrogen Balances

The nitrogen balances are calculated based on the combination of the soil surface and farm gate balance approach, and are closely linked to the estimation of crop specific fertilizer application rates.

The gross balance is defined as the difference between the different nitrogen inputs:

Nitrogen from mineral fertilizer
Nitrogen from manure
Nitrogen in crop residues
Nitrogen from biological fixation by legmuninosae
Nitrogen from atompsheric deposition

and export by harvested crop material. In order to get a more refined pressure indicators on soils and water, an emission factor approach estimates gaseous losses during manure storage and in stable as well as during application of organic and merinal fertilizer, and thus calculates the nitrogen which could either run-off, leach below the root zone or be stored in soils.
