Long-term study maps greenhouse gas emissions from agricultural soils

Climate change and cropland management compromise soil integrity and multifunctionality

Soils provide essential ecosystem functions that are threatened by climate change and intensified land use. We explore how climate and land use impact multiple soil function simultaneously, employing two datasets: (1) observational – 456 samples from the European Land Use/Land Cover Area Frame Survey; and (2) experimental – 80 samples from Germany’s Global Change Experimental Facility. We aim to investigate whether manipulative field experiment …

Agricultural greenhouse gas emissions

Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there's more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it's vital to find ways to curb those emiss…

Understanding the carbon landscape: Reducing carbon in agriculture

Agriculture, a cornerstone of global food security, stands at a critical intersection in the face of the escalating climate crisis. While essential for feeding the world, the sector is also a contributor to greenhouse gas emissions.  Understanding your emissions is crucial for climate change mitigation, according to the latest edition of Absa’s AgriTrends report. Agricultural […] Understanding the carbon landscape: Reducing carbon in agriculture…

Illinois Leads Most Rigorous Agricultural Greenhouse Gas Emissions Study to Date

Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there’s more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it’s vital to find ways to curb those emissi

Illinois Conducts Most Comprehensive Study on Agricultural Greenhouse Gas

In the heart of America’s agricultural landscape, a groundbreaking study conducted by researchers at the University of Illinois Urbana-Champaign has shed unprecedented light on the elusive dynamics of greenhouse gas emissions from soil. This research rigorously quantified emissions of nitrous oxide (N₂O) and carbon dioxide (CO₂) across commercial corn and soybean fields, with a precision and scale far beyond prior efforts. Understanding these em…
