Switchgrass is an important prairie grass and a handsome landscaping plant as well, lending a golden color to the autumn landscape. ... ‘Heavy Metal’ thrives in prairie type settings or in sunny gardens with moist, average or dry soils. PCR amplicons were purified using SPRI Beads and quantified using a Qubit fluorometer (Thermo Fisher Scientific Inc., Waltham, MA, USA). (2014) to cover the range of soil types and conditions of the southern regions of both states. In contrast to what was observed for the intensive sites, all four data types (lipid, 28S rRNA, 16S/18S rRNA, and NifH) separated communities by crop in the extensive sites (Table 2 and Fig. Three composite samples were taken at random from each of the sampling units. Because soil microbes drive many of the processes underpinning ecosystem services provided by soils, understanding how cropping systems affect soil microbial communities is important for productive and sustainable management. To help reduce dependence on fossil fuels, there is great interest in using plant biomass for energy. To test this hypothesis, we sampled over a larger geographic scale, including sites in two states with a range of soil conditions, with different times since crop conversion, and under two different sampling strategies. Indval analysis was limited to clusters with at least 10 sequences. For the more recently established intensive sites, soil type was more important than plant community in determining microbial community structure, while plant community was the more important driver of soil microbial communities for the older extensive sites where microbial communities under corn were clearly differentiated from those under switchgrass and restored prairie. Soils with higher C and clay contents are often associated with higher microbial biomass because there is more C available for microbial growth (Bach et al., 2010). Our initial hypothesis that soil microbial communities under switchgrass and mixed grasses would be more like those under prairies was confirmed in the older, extensive sites, but not in the young, intensive sites. 2d). Intensive sites were located at the Arlington Agricultural Research Station (AARS) in Wisconsin and at the Kellogg Biological Station (KBS) in Michigan (triangles). Comforting, isn’t it? PCR amplification of template DNA was also performed using the primers LR3 (5′‐CCGTGTTTCAAGACGGG‐3′) and LR0R (5′‐ACCCGCTGAACTTAAGC‐3′) (Liu et al., 2012). If you live east of the Rocky Mountains, you've probably encountered switchgrass, perhaps without even realizing it. COREMIC: a web-tool to search for a niche associated CORE MICrobiome. Contact Us . Switchgrass. Impact of newly introduced perennial bioenergy crops on soil quality parameters at three different locations in W‐Germany One of my subscribers suggested that i keep mowing it down an it will die. We characterized and compared soil microbial communities under restored prairie and three potential cellulosic biomass crops (corn, switchgrass, and mixed prairie grasses) in two spatial experimental designs – side‐by‐side plots where plant communities were in their second year since establishment (i.e., intensive sites) and regionally distributed fields where plant communities had been in place for at least 10 years (i.e., extensive sites). ‘Prairie Fire’ has a fibrous root system that grows to more than 10 feet deep, making it drought tolerant. All 28S LSU rRNA sequences were first processed through RDP's pyrosequencing initial processing tool (http://pyro.cme.msu.edu/). All agricultural activity affects biodiversity, soil fertility, and water resources (Groom et al., 2008), and these factors should be assessed when evaluating the sustainability of biofuel cropping systems. blond little girl standing in front of pampas grass - switchgrass stock pictures, royalty-free photos & images. Purchase a Gift Certificate . Significant efforts are underway to understand what biomass crops should be grown, where they should be grown, and how they can be managed in sustainable ways (Kim et al., 2012; Gao et al., 2013; Werling et al., 2014).
