Nitrogen surplus from agriculture impacts groundwater, according to 70 years of monitoring

September 29, 2017

A 70 years time-series of monitoring data relays a clear message: When farmers apply more nitrogen to their fields than their crops can absorb, the amount of nitrogen in the groundwater increases. When less nitrogen leaches from the soil, due to either improved management or reduced nitrogen application, the amount found in the groundwater decreases. […]

Winter cold extremes linked to high-altitude polar vortex weakening


first study to show that changes in winds high up in the stratosphere substantially contributed to the observed winter cooling trend in northern Eurasia. study lends further support that a changing Arctic impacts the weather across large swaths of the Northern Hemisphere population centers. changes in the jet stream that drives our weather can lead […]

A better farm future starts with the soil; Opinion on the next Farm Bill

September 22, 2017

With extreme weather events on the rise and farmers and foresters feeling the effects of a changing climate, however, soil health is now at the forefront of our national conversation. Within the next year, the new 5 year Farm Bill will be reauthorized with implications for every aspect of food and agriculture in the US […]

Quantifying soil carbon measurement for agricultural soils management: 11 white papers


Regardless of what approach is pursued, reliable and cost effective quantification methods are critical to designing and implementing improved management of soil organic matter including soil organic carbon, and C sequestration policies in the land use sector. Together the group, including Point Blue, produced a set of 11 white papers related to soil organic carbon quantification– see […]

Changes in non-extreme precipitation may have not-so-subtle consequences


Everyday precipitation events — not just the extremes — are changing It’s not just the amount of rainfall that’s important …it’s the duration of that rainfall and the amount of time between rainfall and dry periods Hydroelectric plants, storm water drainage systems — any structure that relies on an assumption of expected precipitation — could […]
