Water-table-driven greenhouse gas emission estimates guide peatland restoration at national scale

Autor: J. Koch, L. Elsgaard, M. H. Greve, S. Gyldenkærne, C. Hermansen, G. Levin, S. Wu, S. Stisen

Publikováno v: Biogeosciences, Vol 20, Pp 2387-2403 (2023)

The substantial climate change mitigation potential of restoring peatlands through rewetting and intensifying agriculture to reduce greenhouse gas (GHG) emissions is largely recognized. The green deal in Denmark aims at restoring 100 000 ha of peatla

Oblique geographic coordinates as covariates for digital soil mapping

Autor: A. B. Møller, A. M. Beucher, N. Pouladi, M. H. Greve

Publikováno v: SOIL, Vol 6, Pp 269-289 (2020)

Decision tree algorithms, such as random forest, have become a widely adapted method for mapping soil properties in geographic space. However, implementing explicit spatial trends into these algorithms has proven problematic. Using x and y coordinate

Soil organic carbon predictions in Subarctic Greenland by visible–near infrared spectroscopy

Autor: M. Ogrič, M. Knadel, S. M. Kristiansen, Y. Peng, L. W. De Jonge, K. Adhikari, M. H. Greve

Publikováno v: Arctic, Antarctic, and Alpine Research, Vol 51, Iss 1, Pp 490-505 (2019)

Release of carbon from high-latitude soils to the atmosphere may have significant effects on Earth’s climate. In this contribution, we evaluate visible–near-infrared spectroscopy (vis-NIRS) as a time- and cost-efficient tool for assessing soil or

Annual emissions of CH4 and N2O, and ecosystem respiration, from eight organic soils in Western Denmark managed by agriculture

Autor: S. O. Petersen, C. C. Hoffmann, C.-M. Schäfer, G. Blicher-Mathiesen, L. Elsgaard, K. Kristensen, S. E. Larsen, S. B. Torp, M. H. Greve

Publikováno v: Biogeosciences, Vol 9, Iss 1, Pp 403-422 (2012)

The use of organic soils by agriculture involves drainage and tillage, and the resulting increase in C and N turnover can significantly affect their greenhouse gas balance. This study estimated annual fluxes of CH4 and N2O, and ecosystem respiration

The application of GIS based decision-tree models for generating the spatial distribution of hydromorphic organic landscapes in relation to digital terrain data

Autor: R. Bou Kheir, P. K. Bøcher, M. B. Greve, M. H. Greve

Publikováno v: Hydrology and Earth System Sciences, Vol 14, Iss 6, Pp 847-857 (2010)

Accurate information about organic/mineral soil occurrence is a prerequisite for many land resources management applications (including climate change mitigation). This paper aims at investigating the potential of using geomorphometrical analysis and
