Feb. 6, 2024 Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors ...
Jan. 18, 2023 Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental ...
Feb. 14, 2022 Nitrogen fertilizers are critical for growing crops to feed the world, yet when applied in excess can pollute our water for decades. A new study provides six steps to address nitrogen pollution and ...
Apr. 10, 2023 Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off ...
Aug. 25, 2021 Unrealistic and flawed scientific experiments mean the true impact of nitrogen pollution on the environment is unknownremains poorly understood, a new study ...
Aug. 7, 2022 Researchers have found a way to reduce the amount of nitrogen fertilizer needed to grow cereals such as rice, wheat and ...
Aug. 6, 2021 It was long assumed that cyanobacteria were mainly responsible for fixing nitrogen on early Earth, thus making nitrogen available to the biosphere. Researchers now show that purple sulfur bacteria ...
May 28, 2021 Scientists have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural ...
Nov. 29, 2022 The Wadden Sea is an extremely productive ecosystem whose food web is supported by benthic organisms, feeding on primary producers. Marine biogeochemists show where (part of) this exceptional ...
Oct. 16, 2023 The growing global population needs sufficient food. Its production causes overfertilization and increased nitrogen concentration in agriculture, which negatively affects the population, climate, and ...
