Monitoring soil structure changes after compaction

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.

Optimizing feeding is necessary to maintain milk production in organic herds

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.

Organic conditions boost flavonoids and antioxidant activity in onions

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.
