Presentation

Background

  • Agronomist Diploma 2002
  • AgrD autumn 2009
  • Postdoc. at INRA (InfoSol) France 201

Focus on soil mapping in particular using near infrared reflectance (NIR) spectroscopy. Using gamma-spectrometric surveys in soil mapping. Within-field variations in nitrogen mineralization and the possibilities to predict it.

Research interests

Key words: Multivariate statistics, pedometrics, geostatistics, geographical information system (GIS), precision agriculture, digital soil mapping, chemometrics, proximal sensors

Projects

In-field diffuse reflectance farm soil mapping - identification of key spectral features and interactions

I am also involved in:

  • In field farm soil mapping of top and sub soil
  • Identifying critical areas and transport pathways for phosphorus
  • Validation and implementation of the NIR technology in the rutines of soil laboratories for cost effective farm soil mapping
