The following graphs and charts summarize results from Julie Jastrow's research up to 1992.
Trends in the Numbers of Prairie and Weedy Species Observed in Restored Prairie Plots at Fermilab. The number of prairie species (green line) increase over time while the weed species (orange line) decrease over time.
Macroaggreagate Development in a Prairie Soil Prairies soil supports larger soil aggregates. The graph shows the percentage of soil tied up in large aggregates for corn fields (approx. 25-60%), restored prairies (approx.55-95%) and remnant (virgin) prairies (approx. 85-100%). The percentage increases with each growing season for the restored prairie.
Above and Below Ground Plant Biomass (June 17-27, 1985) Blue hatched represents prairie forbs, green represents grasses, yellow hatched represents rhizomes and brown represents roots. The weight of each of these plant types is shown corn restored prairie, pasture (non-prairie plants) and virgin prairie. The amount of biomass of roots and rhizomes increases over time in the restored prairie.
Changes in Total Fibrous Root Length, Length of Colonized Fibrous Roots, and Percent Colonization
Extraradical Hyphal Length (0-10 cm depth) Hyphae are the tube-like structures that contain living protoplasm of fungus. This length increases over time in restored prairie.
Soil Processes Influenced by Soil Structure (physical, nutient and carbon cycling)
Classification of Soil as Habitat for Soil Biota
