“…S ericea lespedeza [ Lespedeza cuneata (Dumont de Courset) G. Don, SL] has many uses as an herbaceous perennial legume (Mosjidis, 1996, 2010; Muir et al, 2014). Its wide adaptation has resulted in naturalization throughout much of the southeastern United States of America (Hoveland et al, 1990; Diggs, Jr., et al, 1999), to the point that it outcompetes native species in some ecosystems (Mantz et al, 2013; Coykendall and Houseman, 2014). Traits such as adaptation to a wide range of climates and soils, ease of establishment, persistence under grazing [‘AU Grazer’ was released by Mosjidis (2001) as grazing tolerant], and high crude protein (CP) concentration have translated into a wide interest in using it as a pasture component throughout the world (Mkhatshwa and Hoveland, 1991; Mosjidis, 2001; Pitman, 2006).…”

Sericea lespedeza [Lespedeza cuneata (Dumont de Courset) G. Don., SL] is a perennial, warm‐season forage legume with wide adaptation, freeze tolerance, establishment ease, and persistence under grazing. It has high condensed tannin (CT) concentrations (g kg−1), which could be useful for methane mitigation and rumen bypass protein, as well as insect pest and gastro‐intestinal nematode suppression. However, CT concentration is variable. Our objective was to test CT, crude protein (CP), and fiber concentrations at five locations (Georgia, Alabama, North Carolina, Louisiana, and Texas) during a growing season. Established ‘AU Grazer’ SL regrowth and accumulated herbage in separate trials was sampled starting late April 2010 every 35 d for four dates. Regrowth CP concentration ranged (P ≤ 0.05) from 127 g kg−1 in North Carolina on date 3 up to 221 g kg−1 in Alabama on date 1. Sericea lespedeza regrowth in the warmest latitude (Louisiana) consistently contained among the greatest (P ≤ 0.05) acid detergent fiber. In regrowth herbage, we recorded a wide (P ≤ 0.05) total CT range, from 133.5 mg kg−1 in Texas on date 3 to 46.1 mg kg−1 in Louisiana on date 1, reflecting variability in fiber‐bound, protein‐bound, and especially extractible CT. Results from accumulated herbage reflected (P ≤ 0.05) herbage ontogenesis with less CP and greater fiber concentration with maturity but showed the same lack of CT concentration pattern as the regrowth herbage. These results indicate that SL herbage nutritive value and CT concentration is variable, so that any hay or pellets sold commercially for CT content should be assayed by environment and crop maturity.

“…In this article, we only quantified the soil microbial community not changes in soil nutrient dynamics even though PSF can also manifest through soil nutrients (Perkins & Nowak 2013a;Coykendall & Houseman 2014;Mehrabi et al 2015;Waring et al 2015). The PSF created by B. inermis may at least partially be attributed to alteration of N cycling (Vinton & Goergen 2006;Mahaney et al 2015;Piper et al 2015a).…”

“…During growth, plants influence soil conditions through root deposition and exudation (Wardle et al 2004), nutrient uptake (Perkins et al 2011), mining and immobilization of nutrients (Perkins et al 2011), and accumulation and selection of microbial communities (Klironomos 2002;Jordan et al 2008). PSFs can change subsequent individual plant performance (Perkins & Nowak 2013a;Coykendall & Houseman 2014), fitness (Espeland 2013), competitive relationships among plants (Perkins & Nowak 2012), and community development (Perkins & Hatfield 2014). Treatments such as microbial inoculum or microbial inhibitors have been used in restoration settings to remediate microbial PSFs.…”

Seedling performance is often a limiting factor in ecological restoration. Changes in the soil microbial community generated by invasive plants contribute to seedling failure. A method to remediate invasive species‐induced changes to the soil microbial community that results in increased native species seedling performance and decreased invasive species seedling performance could have a large impact on the success of many restoration efforts. In a greenhouse experiment, we first examined the changes in the soil microbial community created by invasive compared to native grasses. Then, we investigated four microbial treatments (bacterial inoculant, fungal inoculant, fungicide, and bactericide/fungicide) to remediate microbial plant–soil feedbacks (PSFs) created by invasive species Bromus inermis and Poa pratensis and increase the performance of natives Andropogon gerardii, Elymus canadensis, Pascopyrum smithii, and Schizachyrium scoparium. We found that the PSF mitigation treatments had some context‐dependent utility for restoration. For example, all of the treatments decreased the performance of B. inermis and fungal inoculant decreased the performance of P. pratensis. However, no single treatment increased the performance of all natives. Fungicide increased the performance of A. gerardii and E. canadensis in soil previously occupied by B. inermis and the performance of S. scoparium in soil previously occupied by P. pratensis. If validated in the field, PSF mitigation treatments may have utility for restoration practitioners.

“…In temperate forest ecosystems, such legacies can reduce invasive exotic performance in mixture with natives (Shannon, Flory & Reynolds ), creating negative feedback that suppresses invasion. Neutral legacies have been observed (Smith & Reynolds ; Coykendall & Houseman ) in temperate forests and grasslands, respectively. Notably, legacy effects can be dependent on competitive context; e.g.…”

Summary Semi‐natural perennial grasslands are of increasing importance as components of multifunctional agroecosystems, combining biomass production with provision of other ecosystem services. Soil legacies from previous land use or exotic species can hinder their establishment, but might be overcome through a multi‐stage successional strategy, whereby certain species are used to facilitate native grassland species establishment. We tested this strategy via a feedback experiment examining soil‐conditioning effects on interference interactions between native and exotic species. Soils in a former maize–soybean production field in Minnesota, USA, were conditioned for 3 years with native or invasive exotic perennials or a maize–soybean crop rotation. Nitrogen (N) fertilization was an additional treatment in field plots. In a greenhouse, native and invasive exotic perennial grassland seedlings were grown on these soils, in monoculture and in native–exotic species pairs, with and without N fertilization. The impact of soil conditioning and field and greenhouse N fertilization on interactions between native and exotic seedlings in mixture was determined. Neighbouring plants suppressed biomass production in all native and exotic species. The maize–soybean rotation left a soil legacy that enhanced suppression of native species when grown with exotic species, while exotic species suffered no such disadvantage. The strong and specific disadvantage to native species of maize–soybean soils decreased with greenhouse N fertilization, but remained significant, while field N addition did not alter this effect. Synthesis and applications. We found that the negative soil legacy of the maize–soybean rotation for native plant performance in interaction with exotics was greatly diminished in soils conditioned by native or exotic perennial species, irrespective of nitrogen addition. This highlights the potential value of perennial species in conversion from row‐crop agriculture to grasslands, because all perennial species alleviated the enhanced suppression of natives observed on maize–soybean soils. We did not find strong evidence that these perennial species were capable of specifically facilitating native species over exotics, but a broader range of species should be evaluated.
