This laboratory will focus on two types of commonly measured soil hydraulic properties: the soil-water retention curve and saturated hydraulic conductivity. Soil samples to be used for measurements are a sandy loam soil material that has been mixed with compost at three rates, as discussed in the guest lecture.In class we will demonstrate and discuss the measurement procedures used for data collection. Water retention measurements take several days to weeks for measurement, depending on the number of pressures included, due to required equilibration time. As such, the data you will work with have been collected over several weeks. You will be provided with a combined data set including raw data for 3 sample/compost mixtures × 3 reps for analysis and to prepare your reports.Our goals for this laboratory report are to compare both variability within measurements and variation across soils. For your reports include the following components:I) Summary of measurement results. Include tables and/or figures indicating the mean and standard deviation or coefficient of variability for each soil/compost mixture based on water retention (i.e., water content) at each pressure and saturated hydraulic conductivity. Note that saturated hydraulic conductivity may vary by orders of magnitude for a given soil, so you may wish to use a log transformation of your data when computing and comparing means. Discuss whether results appear reasonable, and where appropriate based on results, discuss sources of error or problems with measurements.II) Comparison of results across treatments. Contrast results for each property between different levels of compost amendment. Discuss connections and interrelationships among the soil hydraulic properties we measured. In your discussion consider what these properties tell you about differences in the general characteristics of the mixtures and what this might mean for water storage and flow in roadside stormwater management.III) Sample calculations. For each property, include a sample calculation demonstrating how you used the raw data to generate the estimates of the properties you have presented in part I.Parts I and II of your report should be typed and a maximum of three pages in total
