Soil Temperature and Yeast Growth


    Soil research is one of the fastest-growing areas of modern science.  The E.S.S.R.E. program was meant to promote research and discover new information about soil sciences. We ran field surveys on the plots of soil we tested (20m x 20m). Our soil had a primarily neutral pH that was a bit acidic. We also had very high numbers of fungi within our plot. Each plot had a specific microclimate, the climate of a small, specific place within an area as contrasted within the climate of the entire area. Among microclimates, our plot was  distinguished by a monoculture growth of jewelweed. Among the four plots tested by the ESSRE researchers, only two had jewelweed and those two differed in the amount of sun the soil under the jewelweed received. These unique characteristics were the initial factors in deciding what we would research. 


    Our group decided to use all of our distinctive data to form an experiment for research. Our group tested with yeast, true fungi that lack chlorophyll and characterized by wide dispersion of natural habitats. We tested yeast and how it grows in relation to soil temperature in an area with common vegetation. Our vegetation was jewelweed,  a North American annual plant with usually yellow or orange flowers; grows chiefly on wet rather acid soil, also known as touch-me-not. However, the vegetation can vary depending on where you are testing from.
