Publikováno v: Forest Ecology and Management 479 (2021)
Forest Ecology and Management, 479
The substitution of biomass for fossil fuels in energy consumption is a measure to decrease the emissions of greenhouse gases and thereby mitigate global warming. During recent years, this has led to an increasing interest to use tree harvest residue

Marktverkenning biomassareststromen hout uit landschap
Autor: J.H. Spijker, Bas Lerink, Iris Vural Gürsel, Wolter Elbersen
Woody biomass from landscape elements is currently primarily used for energy generation (heat and electricity). Developing high-value applications for this type of biomass is complicated, due to its relatively low quality, the lack of uniformity and

Het effect van houtoogst op nutriëntenbalansen in bossen op zandgronden : onderbouwing van een adviessysteem
Autor: Hans Kros, Wim de Vries, J.H. Spijker, Anjo de Jong
Dit rapport beschrijft de onderbouwing van een adviessysteem dat bosbeheerders helpt bij het kiezen van het oogstsysteem, namelijk het oogsten van uitsluitend stamhout of ook top- en takhout, bij een gegeven houtoogstniveau. Het adviessysteem richt z

Patterns in soil quality: Natural geochemical variability versus anthropogenic impact in soils of Zeeland, The Netherlands
Autor: Simon P. Vriend, J. N. de Jong, P.F.M. van Gaans, J.H. Spijker
Publikováno v: International Journal of Geographical Information Science. 21:569-587
We demonstrate a structured approach to identify natural as well as anthropogenic geochemical patterns in sedimentary soils, using statistical techniques that increase in complexity and the requirements for auxiliary data. Comparison with the average
