Soil erosion modeling: It's getting better all the time

About 50 years ago, scientists at the U.S. Department of Agriculture (USDA) devised the Universal Soil Loss Equation (USLE), a formula farmers could use to estimate losses from soil erosion. Agricultural Research Service ...

Following the path of chemicals through the soil

Where do pesticides and their degradation products go once they enter the soil? And how long does it take them to get to groundwater or drainage systems? That depends on a number of factors, but researchers at Aarhus University ...

Allotments yield food and healthy soil, study finds

Soils under Britain's allotments are significantly healthier than intensively farmed soils, researchers have found. This is the first study to show that by growing at small-scale in urban areas, it is possible to produce ...

New model predicts high-speed rail vibrations

Scientists have developed a new model to predict how much a new high-speed railway would shake the ground around it, and the effect this could have on those living near the line.

Shedding light on how much carbon tropical forests can absorb

Tropical forest ecosystems are an important part of the global carbon cycle as they take up and store large amounts of CO2. It is, however, uncertain how much this ability differs between forests with high versus low species ...
