Tall Fescue (Festuca Arundinacea) Stockpiling Response To N Fertilizer In Southern Virginia As Affected By Biological Soil Quality, Christopher D. Teutsch, Robert Shoemaker, Alan J. Franzluebbers

IGC Proceedings (1997-2023)

Cattlemen in the eastern USA profitably utilize endophyte-infected tall fescue (Festuca arundinacea) for fall-stockpiled winter grazing. Ergot alkaloid concentration in fescue tends to decline in winter. This improves the quality of fescue for grazing when the supply of other forage becomes limited on most farms. Tall fescue dry matter yields generally respond favorably to nitrogen (N) inputs, but response can be limited with summer application due to accumulation of biologically available N in soil. Research is needed to characterize a diversity of pastures for response to N fertilizer during fall stockpiling.

Biological soil quality can be estimated with …

Soil Carbon And Nitrogen Stocks And Their Relationship With Plant And Soil Dynamics Of Degraded And Artificial Restoration Grasslands In An Alpine Region, Yuanyuan Li, Shikui Dong, Yu Wu

IGC Proceedings (1997-2023)

Land disturbances and management approaches can significantly alter grassland soils. Therefore, understanding the carbon and nitrogen storage accompanying plant and soil physical and chemical properties due to anthropogenic disturbance and different management strategies is important. In our study, we investigated carbon and nitrogen storage in artificial grasslands with different durations of restoration and native grasslands with different levels of degradation. We found that total carbon and nitrogen were significantly higher five years after restoration than after seven and nine years, but decreased due to grassland degradation. Furthermore, soil carbon and nitrogen had a close relationship with plant and soil factors, …
