Soil compaction is a global threat to soil ecosystem services, causing tremendous costs to society. The costs of soil compaction are borne by the cumulative loss of soil functionality (e.g. yield loss) following a compaction event until the soil has functionally recovered. Although soil compaction is relatively widely studied, there is a lack of reliable observations and metrics for soil structure recovery rates after compaction.
Currently, agriculture accounts for approximately 9% of total US greenhouse gas (GHG) emissions. By varying diet formulation and the associated crop production to supply the diet, farmers can affect the quantity of GHG emissions of various feeding systems. Therefore, researchers have created a study to compare the effects of feeding strategies and the associated crop hectares on GHG emissions of Wisconsin certified organic dairy farms.
Five years ago, a highly publicized meta-analysis of more than 200 studies concluded that organic food was no more nutritious than conventionally grown food. Since then, however, additional work has suggested the organic foods contain more health-benefiting phytochemicals. Now, researchers have found that flavonoid levels and antioxidant activity in organic onions are higher than in conventional onions. Their investigation is the longest-running study to address the issue.
The goal to offset rises in atmospheric greenhouse gas concentrations by increasing soil carbon storage by 4 per mille (0.4%) per year is unrealistic, say scientists in a new article.
If you're small, smells are a good way to stand out. A team of researchers has demonstrated for the first time that two different types of micro-organisms -- bacteria and fungi -- use fragrances, known as terpenes, to hold conversations. And that's not all. The researchers suggest that terpenes are the most popular chemical medium on our planet to communicate through.
Glaciers and ice sheets have recently been considered significant sources of organic carbon and provide nutrients to downstream marine ecosystems.
As climate change continues to impact the Antarctic, glacier melt and permafrost thaw are likely to make more liquid water available to soil and aquatic ecosystems in the McMurdo Dry Valleys, potentially providing a more nutrient-rich environment for life, according to a new study.
Many people choose organic thinking it's better for humans and the planet, but a new study finds that might not always be the case.
