Soil Carbon and Nitrogen Dynamics on Sandhills Wet Meadows
November 29, 2021 @ 3:00 pm - 4:00 pmFree
Biography: Martha Mamo holds the John E. Weaver Professorship and currently serves as the Head of the Department of Agronomy and Horticulture at the University of Nebraska-Lincoln (UNL). Mamo’s research is on nutrient cycling in low input rangeland ecosystem – evaluating grazing strategies and dung pat impact on soil C and N. Mamo provided leadership in the undergraduate curriculum and taught two core large enrollment soil courses for 15+ years. She received her B.Sc. and M.Sc. from Alabama A&M University, and Ph.D. from the University of Minnesota.
Presentation: Decomposition of organic materials in grasslands leads to nutrient availability and nutrient cycling, which define quality and functionality of rangeland ecosystems. The inputs to the system include urine, dung, litter, and trampled vegetation and maybe influenced spatially and temporally by the grazing strategy. The nutrient cycling model of this grazed system as well as temporal changes in soil C will be reported for a grazing study conducted at the Barta Brothers Ranch in the meadows of the Sandhills region of Nebraska.
