Acidification of Biogas Residues Stimulates Manganese Uptake in Wheat

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Efficient application of organic fertilizers contributes to resource‐efficient agriculture. Acidification of liquid manure effectively reduces ammonia (NH3) emissions. However, the effect of acidification on other plant nutrients, such as Mn, often a yield‐limiting nutrient in cereal production, is not well understood.

Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

Limnology and Oceanography, EarlyView.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Picophytoplankton act as the primary consumers of excess phosphorus after the spring bloom in the eutrophic Baltic Sea

Limnology and Oceanography, EarlyView.
Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...
