Kansas State classes get a lesson in environmental remediation
Kansas State University professors transformed a plot of land from a problem to a classroom, teaching students on the fly to remediate nutrient pollution. Saugata Datta, an associate professor of geology, and Nathan Nelson, an associate professor of agronomy, taught students to evaluate, sample and remediate land using Kansas Department of Health and Environment protocols. It started when Chris Steincamp, an environmental lawyer and KSU alumnus, asked Datta if his geology students could restore a tract of land in Sylvan Grove Kan. Datta jumped at the opportunity to give his students hands-on experience in a process usually reserved for regulators and consultants. It helped that O.C.

Choptank River watershed nitrate monitoring targets conservation efforts
A nutrient monitoring effort throughout a degraded Chesapeake Bay watershed is helping chart the path of nitrate through the system. The monitoring is part of a plan to target federally funded agricultural conservation practices to the places in the watershed that need them most. The Choptank River is among one of the largest tributaries to the Chesapeake Bay, a system plagued by excess nutrients. The Choptank flows across the Delmarva Peninsula, a 170-mile-long piece of land that makes up the bay's eastern shore. More than half of the Choptank's watershed is covered in agricultural land, which is part of the reason the river has been listed as impaired under Clean Water Act standards for nutrients and sediment.

Total algae sensor is the newest addition to YSI's EXO sondes
Many algae sensors can detect Chlorophyll a or levels of blue-green algae. YSI’s new Total Algae Sensor can measure both at the same time. “If you’re only looking at Chlorophyll a, you can miss a very big portion of total algae biomass,” said Tim Finegan, product manager. The new sensor is an optional attachment to the company’s line of EXO sondes, which debuted earlier this year . It’s an optical probe and maintenance is limited to keeping the sapphire windows on the unit clean. The Total Algae Sensor can be calibrated in two different ways, one for spot sampling and one for continuous sampling, which allows users to make sure readings are accurate for their specific monitoring applications.
