Phosphate sorption characteristics of European alpine soils

Soil chemistry plays an important role in the composition of surface waters. In areas with limited human activities, properties of catchment soils directly relate to the exported nutrients to surface waters. Phosphate sorption ...

How wildfires change soil chemistry

The huge, long-lasting wildfires that have become increasingly common in recent years can cause changes in soil chemistry that affect water contamination, air quality, and plant growth. But these changes are poorly monitored ...

Small wetlands can have big impacts

Crops need nutrients like nitrogen and phosphorus to grow and thrive. However, excess nutrients from farms can wash into streams and rivers, and even make their way into oceans. The surplus in nutrients can cause major damage ...

Lake Tahoe clarity improves, outlook not so clear
