The main C and N fluxes of a winter rapeseed field in Central Estonia were quantified for one year to identify the highest fluxes and major sources of uncertainty. Greenhouse gas emissions were measured with the closed chamber method, leaching losses were estimated by combining the soil water balance and leachate analyses, and soil C and N changes...
Riparian forests are known as hot spots of nitrogen cycling in landscapes. Climate warming speeds up the cycle. Here we present results from a multi-annual high temporal-frequency study of soil, stem, and ecosystem (eddy covariance) fluxes of N 2 O from a typical riparian forest in Europe. Hot moments (extreme events of N 2 O emission) lasted a qua...
The carbon (C) budgets of riparian forests are sensitive to climatic variability. Therefore, riparian forests are hot spots of C cycling in landscapes. Only a limited number of studies on continuous measurements of methane (CH4) fluxes from riparian forests is available. Here, we report continuous high-frequency soil and ecosystem (eddy-covariance;...
Tree stems play an important role in forest methane (CH4) and nitrous oxide (N2O) flux dynamics. Our paper aimed to determine the unknown diurnal variability of CH4 and N2O exchange in grey alder tree stems. The gas fluxes in tree stems and adjacent soil were measured using manual static and dynamic chamber systems with gas chromatographic and lase...
Biochar, a carbon-rich material resulting from pyrolysation, is one of the proposed alternatives as a substrate component to peat. The aim of this study was to investigate the effect of different ratios of peat substitution with a locally available hardwood biochar on the chemical characteristics of growing media, seed germination, plant morphologi...
The development of new options to reduce ammonia (NH3) emissions during slurry manure storage is still required due to the shortcomings of the current technologies. This study aimed to identify to what extent untreated and acid-treated biochar (BC) and pure acids could reduce ammonia nitrogen (NH3-N) volatilization and increase nitrogen retention i...
The decomposition of fresh crop residues added to soil for agricultural purposes is complex. This is due to different factors that influence the decomposition process. In field conditions, the incorporation of crop residues into soil does not always have a positive effect on aggregate stability. The aim of this study was to investigate the decompos...
Nitrification inhibitors have been proposed as a tool to mitigate nitrous oxide (N2O) emissions from agriculture, which are caused mainly by fertilization. The nitrification inhibitor 3,4-Dimethylpyrazole phosphate (DMPP) was tested in a winter rapeseed field after dairy slurry application in Central Estonia. N2O emissions were monitored using the...
Riparian forests are known as hot spots of N cycling in landscapes and climate warming speeds up the cycle. Here we present results from the first multi-annual high temporal-frequency study of soil, stem and ecosystem (eddy covariance) fluxes of N2O from a typical riparian forest in Europe.
Hot moments (extreme events of N2O emission) last a quarte...
The importance of permanent grasslands in the feed production has decreased in Estonia in the last decades, because of the low feeding value of the biomass. Therefore, there is a need for new solutions for utilization of this biomass. One way of giving value to this resource would be its application in the production of biochar (BC) and its subsequ...
One of the characteristics of global climate change is the increase in extreme climate events, e.g., droughts and floods. Forest adaptation strategies to extreme climate events are the key to predict ecosystem responses to global change. Severe floods alter the hydrological regime of an ecosystem which influences biochemical processes that control...
Biochar has been proposed as an amendment that can improve soil conditions, increase harvest yield, and reduce N losses through NO3− leaching and N2O emissions. We conducted an experiment to test the hay biochar mitigation effect on N2O emissions depending on its production temperature. The pot experiment consisted of the soil amendment with three...
Forests can be considered as sources and sinks of various greenhouse gases, including methane (CH4) and nitrous
oxide (N2O), due to both natural processes and human actions. Further, they are important carbon (C) and nitrogen
(N) pools. Determining forests contribution to the greenhouse effect requires deeper understanding of nutrient
cycles within...
The closed chamber method is widely used in greenhouse gas (GHG) flux measurement. However, the method has temporal resolution limits, which could be compensated by implementing an automated system. To have a more accurate estimation of the fluxes, automated systems are usually proposed. In opposition to manual chamber measurement, automated system...
Nitrous oxide (N2O) has become a subject of intense research in the last years, not only because of its high global warming potential as a greenhouse gas (almost 300 times that of carbon dioxide), but also for being currently the main ozone-depleting substance. The main anthropogenic source of N2O is agriculture, especially because of organic and i...
Forest soils under elevated soil water content are considered to be a substantial natural source of nitrous oxide
(N2O) and methane (CH4), important greenhouse gases (GHGs). Wetland trees may also contribute to the forest
GHGs exchange by release of both gases into the atmosphere. Extreme climate events, for instance, long lasting
heavy rain or dro...

The general aim of the proposed project is to enhance the sustainable production of wood biomass, interlinking current research efforts started in partnering Nordic and Baltic countries. Three main goals are considered: i) identify and assess the main environmental effects of the intensified use of biomass resources in the Nordic area, ii) evaluate and propose alternatives that can align the co-production of biomass production to complementary ES and iii) seek ways to fully implement
nd realize the resulting strategies and alternatives in existing biomass
production practices and supply chains. These aims build on existing research and datasets among the partner institutions, and involve creation and sharing of experiences and knowledge, research results and existing data and trials concerning biomass production systems
long the Nordic area, as the basis of further developing current and
future research efforts.
