Nitrate levels in soil suggest extreme weather events due to climate change are accelerating groundwater contamination
Researchers at the University of California, Davis will insert devices underground that continuously collect water samples, providing real-time data on the movement of nitrate pollutants. Credit: Isaya Kisekka / UC Davis Extreme weather events caused by climate change, such as droughts and heavy rains, can increase the risk of nitrates from fertilizers entering groundwater, according to a recent study by…

Study finds increased leaching of dissolved organic carbon in soil in rubber plantations
Credit: Journal of Environmental Management (2024). DOI: 10.1016/j.jenvman.2024.122965 Although rubber plantations bring significant economic benefits, large-scale rubber plantations have significant impacts on the ecological environment, especially in terms of soil physical and chemical properties. In a study published in the Journal of Environmental Management, researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) found that the conversion of tropical rainforests to…

Study finds that calcium reduces COâ‚‚ emissions from Arctic soil through mineral formation
Written by Leibniz Zentrum Far Agralandschaftforschung (ZALF) eV Graphical summary. Credit: Environmental Science and Technology (2024). DOI: 10.1021/acs.est.4c07496 In a new study, researchers found that increasing calcium content in soil significantly reduces CO2 emissions. 50% in calcium-poor soils and 57% in calcium-rich soils. The reason is that calcium promotes the formation of the aragonite mineral, which binds CO2 and prevents…
