Project Partners

N-TOOLBOX is a collaborative project involving experts in N management at the farm level from four leading European institutions.

The Nafferton Ecological Farming Group (NEFG), Newcastle University, is a research group within the School of Agriculture focusing on low-input and organic approaches to crop and livestock management. NEFG soil researcher Dr. Julia Cooper coordinates the N-TOOLBOX project, with assistance from soil scientists Dr. Elizabeth Stockdale and Dr. Robert Shiel. Agronomy advice is provided by Dr. Steve Wilcockson.

The Louis Bolk Institute ( (LBI, Driebergen, Netherlands) is a private scientific research institute focussing on agriculture, food quality and health founded in 1976. In the area of agriculture, the LBI started with a focus on organic agriculture and livestock systems, but recently has redirected its research towards the wider area of sustainable agriculture.N-TOOLBOX activities at LBI are lead by Ir. G.J.H.M. van der Burgt who is a specialist in the NDICEA model and has worked on many institute projects on the theme of nutrient use efficiency, predominantly nitrogen. Assistance will be provided by Dr. Ir. C. J. Koopmans, a senior researcher and coordinator of the Soil and Plant department at LBI and Dr. Ir. B. Timmermans.

The Universidad Politécnica de Madrid ( is the oldest and largest Spanish technical university. N-TOOLBOX at UPM is a project of the Agsystems Research Group ( which is lead by Miguel Quemada. Professor Quemada´s research focuses primarily on nitrogen budgets in agricultural systems and the effects of agricultural practices on nitrate leaching. Antonio Vallejo also provides expertise on nitrogen budgets in agricultural systems and the effects of agricultural practices on nitrate leaching and nitrous oxide emissions. Economic analyses are provided by Alberto Garrido, an Associate Professor and expert on the economics of natural resources and risk assessment. Additional assistance with environmental datasets, including climate and soil data analysis, will be provided by Dr. Chiquinquira Hontoria,an Associate Professor and Soil Scientist.

The University of Aarhus ( Vegetables and Crop Physiology Group (VCPG), is responsible for N-TOOLBOX activities in Denmark. This research group is part of the Department of Horticulture, within the Faculty of Agricultural Science at UA ( Dr Hanne L. Kristensen leads the project in Denmark, with additional support from Dr Jørn Nygaard Sørensen. Work at Aarhus in the past has focussed on:
(a) effects of catch crops and green manures in farming
developing models for plant-soil interactions in the rhizosphere
(c) model based decision support systems to optimise N use in crop rotations.
