Nutrient loss pathways from grazed grasslands and the effects of decreasing inputs: experimental results for three soil types [PDF]
Agriculture is a main contributor of diffuse emissions of N and P to the environment. For N the main loss pathways are NH3-volatilization, leaching to ground and surface water and N-2(O) emissions.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

The effect of claying upon the settling of the soil surface on cultivated Sphagnum bogs
Agricultural and Food Science, 1960 The present investigation concerns a Sphagnum bog area that has been under cultivation for 35 years. According to the results, the effect of the claying during this time has been the settling of the surface of the soil on an average 12.5 cm more than in ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

Results from a soil improvement and fertilizing test on fen land at Leteensuo
Agricultural and Food Science, 1961 Clay and sand, used as soil improving agents, have increased the hay crops as well as the cereal crops. When the fertilization contained phosphates only, the increases in crop yield produced by the soil improvement were quite high.

The ash content of the plough layer of peat lands cultivated by different methods
Agricultural and Food Science, 1961 The results of this investigation justify the conclusion that the ash content of peat increases under cultivation through the effects of the administered fertilizers and soil improving agents.

PLANTS, PEOPLE, PLANET, EarlyView.This Open Letter highlights peatlands as critical yet overlooked ecosystems in Brazil's climate and biodiversity policies. By translating scientific evidence into clear, actionable priorities for policymakers, it supports more accurate climate reporting, effective mitigation strategies, and improved land‐use governance.
