The relative abundance of different oxidation states for this important micronutrient varies on the basis of how much available sunlight there is.
Phosphorous stored in watersheds and affects water quality for decades. A new model predicts phosphorus accumulation and depletion, and the consequences for water quality conservation measures.
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
Food production is becoming less efficient at using nitrogen fertilizer, according to a review of global values. Excess nitrogen damages the environment and the climate.
Researchers compared the nitrogen removal potential by microbes in ditches that drained forested, urban, and agricultural lands and discovered that roadside ditches are important areas for removing nutrients.
Mussel shell periostracum and carbonate bound organic matter document seasonal variability in the isotopic composition of riverine suspended particulate organic matter.
Global food systems depend on fertilizers with phosphate. We need to act now before this nonrenewable resource runs out.
Magnetotactic bacteria shunt sulfur, nitrogen, and other important elements between oxygen-poor and oxygen-rich waters.
Researchers track decades of nitrogen inputs and uptake across the United States, highlighting the need for policy to address the legacy effects of this essential nutrient and pollutant.
