“…On aquic soils (Palamas), recovery fraction ranges from 15% to 20% depending on growing year and irrigation treatment. Such a recovery fraction range is reported in literature (Bransby et al, 1989;Sladden et al, 1994) for switchgrass cultivations with fertilization of 75-180 kg N ha -1 . Contrary, in dry soils (Velestino), the recovery fraction remained at low levels (4-6%) pointing the useless effort of adding any nitrogen in switchgrass growing in such soils. )…”

Panicum virgatum could produce cattle feed with lower costs due to the low input requirements and its perennial nature. Dry biomass yield vs. N-P-K nutrient uptake relations as well as the N-mineralization and the N-fertilization recovery fraction for Panicum virgatum (cv. Alamo) were determined under field conditions for four N-fertilization (0, 80, 160 and 240 kg ha -1 ) and two irrigation levels (0 and 250 mm), οn two soils in central Greece with rather different moisture status. It was found that the dry fodder yield on the aquic soil may reach 14 t ha -1 using supplemental irrigation; while on the xeric soil a lower yield of 9-10 t ha -1 may be produced only under supplemental irrigation. Moreover, the average N, P and K concentration was 1.3%, 0.14% and 1.3% in leaves, and 0.5%, 0.85%, and 1.5% in stems, respectively, showing the very low crop requirements. Furthermore, linear biomass yield-nutrient uptake relationships were found with high R 2 , pointing to nutrient use efficiency of 132 and 75 kg kg -1 , for N and K respectively. The base N-uptake ranged from 71-74 kg ha -1 on the aquic to 60 kg ha -1 or less on the xeric soil. Finally, it was found that N-recovery fraction was 20% on the aquic soil and lower on the xeric. Therefore, it could be conclude that Panicum virgatum seems to be a very promising crop for fodder production and its introduction in land use systems (especially οn aquic soils of similar environments) should be taken into consideration.

“…Matching the N application level with N removal has obvious agronomic, economic, and environmental value. Bransby et al [12] fertilized switchgrass with 100 kg ha À1 of N annually four years in the Southeastern USA, and an average of 87 kg ha À1 of N was removed in biomass from the field during the last three. Stout and Jung [13] reported fertilizer N recovery of about 31% and 23% following switchgrass fertilization at 90 and 180 kg ha À1 y À1 in Pennsylvania USA.…”

“…It naturally possesses various traits that make it desirable as a lignocellulosic feedstock, including high yield potential, tolerance to water and nutrient limitations, low establishment costs, mitigation of soil erosion, adaptation to marginal land sites, and a high net energy gain [1][2][3]. While switchgrass is considered a front-running feedstock for bioenergy, the complexity of the cell wall and recalcitrance attributable to compounds such as lignin currently renders the utilization of switchgrass for ethanol production at an economic disadvantage [4].…”

Rapid Assessment of Lignin Content and Structure in Switchgrass (Panicum virgatum L.) Grown Under Different Environmental Conditions

et al. 2009

Switchgrass (Panicum virgatum L.) is a candidate feedstock in bioenergy, and plant breeding and molecular genetic strategies are being used to improve germplasm. In order to assess these subsequent modifications, baseline biomass compositional data are needed in a relevant variety of environments. In this study, switchgrass cv. Alamo was grown in the field, greenhouse, and growth chamber and harvested into individual leaf and stem tissue components. These components were analyzed with pyrolysis vapor analysis using molecular beam mass spectrometry, Fourier transform infrared, and standard wet chemistry methods to characterize and compare the composition among the different growth environments. The details of lignin content, S/G ratios, and degree of cross-linked lignin are discussed. Multivariate approaches such as projection to latent structures regression found a very strong correlation between the lignin content obtained by standard wet chemistry methods and the two high throughput techniques employed to rapidly assess lignin in potential switchgrass candidates. The models were tested on unknown samples and verified by wet chemistry. The similar lignin content found by the two methods shows that both approaches are capable of determining lignin content in biomass in a matter of minutes.
