“…Organic matter amended soils have been observed to exhibit less pronounced 14 changes in microbial phospholipid fatty acid or PLFA (total PLFA, bacterial PLFA, saturated 15 and monounsaturated PFLA) compared to unamended soils under drought conditions (Hueso et 16 al., 2012). Severe disturbances can lead to poor but stable and resistant states that require 17 external inputs to provide a source of energy and nutrients to allow biological colonisation and 18 increase microbial activity (Ohsowski et al, 2012). Besides energy and nutrients, OA may also 19 improve soil structure, cation exchange capacity and water holding capacity, which combined 20 with slow-release of nutrients may benefit below-and above-ground resilience to disturbance resilience of grassland soil microbial community, and therefore soil functions, to drying and 1 rewetting cycles that are projected to increase in frequency and severity in the region.…”

“…Addition of fertilizers, inocula, and conditioners to soil has been widely employed in agricultural settings but little has been done to study the manipulation or addition of soil inocula to improve restoration success (Henegham et al 2008;Ohsowski et al 2012). Recent studies show that amending soils with free-living bacteria can benefit plant diversity and productivity, and accelerate successional processes by tipping the competitive balance in favor of less dominant species (de Deyn et al 2004;Middleton and Bever 2012).…”

The Use of Commercial Bacterial Soil Inoculant Regime in an Urban Prairie Restoration

For successful grassland restoration, commercial soil inoculants are often recommended to increase establishment success. In spring 2009, a 0.94-ha tract was targeted for restoration at Phil Hardberger Park, a 126-ha park in the heart of San Antonio, Texas. Woody species, mainly Texas persimmon (Diospyros texana Scheele), and Ashe juniper (Juniperus asheii Buchholz), were removed and the area was divided into 10 subplots measuring 911 m 2 on average. In September 2009, over 40,000 plugs of seven native grass species were planted. In addition, native prairie seed mixes, including various grass and forb seeds, were sown into the site at a rate of 11.26 kg/ha. Half of the native grass plants were treated with a soil bacteria inoculant plus additional nutrients (IN) (BioGensis IIITM DS Tainio Technology and Technique Inc.), and half were left as controls (C). Soil samples from the plots were taken in February 2010 and 2011 and analyzed for soil nutrients, bacteria, protozoa, and fungi. Vegetation data were collected October 2010 and May and October 2011 to assess differences in percent cover between the treatments. The IN treatment resulted in significantly higher percent cover in the second growing season of three native grasses, Eriochloa sericea (Scheele) Munro ex Vasey, Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths, and B. curtipendula (Michx.) Torr; however, no significant differences were found between the IN and C plots for measures of overall native species abundance, soil resources, or the presence of soil microbes. We concluded that commercial soil inoculants may not have been necessary for the successful establishment of a native grassland community.

“…The interactions described above may help to understand the continued success of cheatgrass as well as challenges encountered with rehabilitation projects targeting B. tectorum invaded sites. Approaches to rehabilitate areas invaded by cheatgrass and other invasives have included the addition of carbon in the form of sugar, straw, sawdust, mulch, biochar or activated charcoal (Beckstead & Augspurger, 2004;Kulmatiski, 2011;Mazzola et al, 2008;Ohsowski et al, 2012, Paschke et al, 2000. The idea behind these applications is that added carbon immobilizes nitrogen in soil bacteria by increasing the C/N ratio (Perry et al, 2010).…”

Plant-soil microbial feedback loops play an important role in the establishment and development of plant communities. Microbial soil communities, including pathogens, plant-growth-promoting rhizobacteria and their reciprocal interactions, can influence plant health and nutrient cycling in many ways. We are proposing a model that accounts for cheatgrass (Bromus tectorum) invasion success and long-term persistence in both disturbed and undisturbed sites. In this model cheatgrass alters soil microbial communities that favor nitrifying microorganisms, resulting in elevated NO 3 -levels. Increased NO 3 -levels, coupled with B. tectorum life history and climatic and edaphic conditions in the semi-arid western U.S., result in long-term persistence of this invasive annual. In ecosystems that lack major precipitation during the growth season, B. tectorum induced shifts in the nitrifier community result in accumulation of plant available nitrogen during the summer when native perennials are primarily dormant. Increased NO 3 -levels can be efficiently utilized by cheatgrass ahead of native perennials during fall and winter. Restoration and management efforts must be guided by a thorough understanding of soil microbe-cheatgrass interactions to avoid nutrient flushes resulting from freeze-thaw and wet-dry cycles that benefit this invasive grass.
