The plantation was only just harvested for the first time, a milestone toward a broader goal of developing the acreage into a renewable and sustainable biomass crop.<\/p>\n<p>The harvesting was no small feat. After the plants were first put into the ground, Penn State scientists had to wait four years for them to mature enough to be cut. But with that out of the way, the willow can now be cut every three years to provide for carbon sequestration but also better water quality and even biofuel production down the road.<\/p>\n<p>Once it gets up and running, managers at the site are hopeful that it will blossom into a more and more efficient batch of willow. It is already much more efficient, they have found, than a nearby crop of corn that was planted for comparison.<\/p>\n<p>To make that determination, researchers involved with the effort have instrumented the fields with a sonic anemometer to measure the horizontal and vertical movements of wind throughout the region.<\/p>\n<p>\u201cAir is constantly fluctuating. With the speed, we can get the flux,\u201d said Armen Kemanian, associate professor of production systems and modeling in the Department of Plant Science at Penn State. And so he and others use that measurement, at a resolution of once every 20 minutes, to track the exchange of carbon dioxide during the day and night. The same approach, he says, gets used to track the exchange of water.<\/p>\n<div id=\"attachment_25251\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-25251\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2016\/04\/shrubwillow.jpg\" alt=\"The shrub willow stand at the Rockview site can continue producing biomass for more than 20 years, according to researchers who intend to use it both as a source of renewable energy and as a platform for sustainability studies.

(Credit: Penn State University)<\/p><\/div>\n<p>\u201cOne of the reasons that bioenergy makes sense is because it removes a lot of carbon dioxide from the atmosphere,\u201d said Kemanian. \u201cIt\u2019s difficult to measure in the soil, so we measure how much carbon moves toward or away from the plant.\u201d<\/p>\n<p>With the same measurements being used at the corn crop, Kemanian has noticed differences between how the two plants perform over time. During the early and late seasons of the year, shrub willows win at pulling in the most carbon dioxide. But during the summer months, whenever the conditions are best for the corn, it pulls ahead.<\/p>\n<p>The real benefits of shrub willows that he sees comes when considering how the plants will impact CO2 concentrations over time. <\/p>\n<p>\u201cThe surprising thing is how early and how late willow hangs in there,\u201d said Kemanian. \u201cThe total biomass is probably similar and I\u2019m not surprised if corn wins, but willow does so with a third of the nitrogen. It\u2019s more efficient and operates at a much lower cost.\u201d<\/p>\n<p>Because of those benefits, he sees some floodplains as the most ideal locations to plant shrub willow plants. They have all the capacity that is needed to continually take up the nutrients and water in those spots while continuing to grow with ease.<\/p>\n<p>But for the crop that\u2019s growing at Penn State, there are bigger aspirations as part of the Northeast Woody\/Warm-Season Biomass Consortium. <\/p>\n<p>\u201cThe goal is to separate what we call sustainable landscapes. And we\u2019re not starting from scratch. There are other areas where this has been successful,\u201d said Kemanian. \u201cSo we want to replace some crops with energy crops, but at the same time there needs to be a market for the biomass. To grow them, harvest them, transport them, there must be an end user and we can\u2019t control that.\u201d<\/p>\n<p><em><span style=\"color: #808080;\">Top image:\u00a0Researchers planted shrub willow seedlings in 2012 on land formerly owned by the State Correctional Institution at Rockview.
