“…This was also true for alfalfa accessions LE2521 and LE2669 and red clover accessions LE1731 and LE1391, which were cultivated in both PE1 and PE2, so it is highly unlikely to be an effect of accession. Large day/night temperature differences can benefit alfalfa growth [68,69]. However, the temperature set-ups in our experiments were not that different (with a day/night temperature of 22.7/17.2 • C in PE1 and 22.5/15.7 • C in PE2).…”

Legumes have a high demand for phosphorus (P) due to energetically costly biological nitrogen fixation, but they also have effective physiological and morphological strategies for P mobilization. To evaluate the inter- and intraspecific P efficiency of small-grain legumes supplied with different P recycling fertilisers, eight accessions each of alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) were cultivated in two pot experiments under greenhouse conditions until the flowering stage. To substantiate the results, some accessions were used in both experiments. Five treatments (no P, triple-superphosphate (TSP), sewage sludge ash (SSA), biowaste compost (compost), and struvite) were considered P sources. In addition to plant P uptake, the soil P pools were analysed in detail. Red clover showed higher yields and nutrient uptakes compared to alfalfa, but intraspecific effects were marginal. The addition of P resulted only partly in an increase in yield, despite the low P content in the soil. While struvite application clearly enhanced the P uptake of the plants in both experiments, SSA application had no effect compared to the control. The same treatment effect occurs with the bio-available soil P contents, which were on average 72.6 mg kg−1 after struvite and 44.3 mg kg−1 after SSA addition. Struvite as a P source was especially effective when applied to red clover. Our study aligns with previous field results and underscores the high potential of P mobilization of small-grain legumes without pronounced inter- or intraspecific differences. While struvite is suitable as a P fertiliser, the application of SSA to legumes is not recommended.

“…These results suggest that areas with low levels of invasion may not reach sufficient intensity to cause sericea lespedeza seed mortality. Perhaps more concerning is that the heat from lower intensity fires may have the undesired result of scarifying the seed coat, which is known to promote germination of sericea lespedeza (Kalburtji et al, 2007; Qui et al, 1995; Segelquist, 1971). Presuming our results are relevant to field‐based observations, the effectiveness of prescribed burning to control for sericea lespedeza may be limited without removing sericea lespedeza prior to burning.…”

Invasion of a non‐native forb reduces flammability in a fire‐dependent ecosystem

Fire and grazing are two of the most common global disturbances that maintain and promote many grassland ecosystems worldwide. The presence of non‐native, invasive plant species can alter fire regimes through changes in fuel properties that affect native vegetation in many ecosystems and are a leading threat to biodiversity and ecosystem function. Sericea lespedeza (Lespedeza cuneata), a non‐native, invasive forb frequently present in many North American tallgrass prairies, may reduce flammability by altering the fuel bed moisture and structural characteristics to reduce fire in this fire‐dependent ecosystem. The goal of this research was to examine the influence of sericea lespedeza on fuel bed structure, moisture, and flammability compared to native grassland fuels. Fuel bed burning trials, conducted in a controlled laboratory setting, tested for the effect of fuel load mass of native grass and sericea lespedeza litter, proportion of sericea fuel load, and fuel moisture content on flammability metrics. Regardless of moisture content, sericea lespedeza reduced flammability and reduced maximum fire temperatures by as much as 500°C. Sericea lespedeza poses a major threat to North American tallgrass prairies by decreasing flammability of fuel beds through increased fuel bed density and moisture retention.
