Homework questions1. Which soil will usually have the higher porosity, a sandy soil or a clay soil? Why?2. How would the compaction of a soil with a bulk density value of 1.3 grams per cubic centimeterto a bulk density value of 1.8 grams per cubic centimeter affect water flow into the soil and plantgrowth? Explain.3. Approximately what proportions of the pore space should be occupied by air and water when asoil is at an optimum condition for plant growth? Explain. Soil Lab 11a Direct Measurement of Soil Porosity1. Fill a 100 ml graduated cylinder to the 100 ml mark with tap water. Tilt the beaker containing thesoil sąved from Step 3 in the Bulk Density Determination to about a 45 degree angle. Pour the watervery slowly onto the soil in the beaker. Stop adding water when the soil pores are filled (saturated)and the soil surface glistens.2. Allow the soil to stand for several minutes to make sure the water has filled the very small soil pores.Any excess water can be returned to the graduated cylinder. Don't stir or shake the mixture.3. Determine the amouht of water used to exactly fill the pote space in the 100 cubic cehtimeters ofsoil. Subtrąct the reading of water level on the side of the graduated cylinder from the originalvolume of 100 ml. Note that the water which was poured onto the soil exactly filled the pore spaceand thus equals the total pore volume by direct measurement.4. Record your results below and make the necessary calculations. Be sure to show formula andcomplete setup and units.5. Repeat steps 1 though 4 with the other soil.Porosity Data:SoilInitial volume of water in cylinder (ml)Volume of water remaining in Cylinder (ml)Volume of water filling soil pores (ml)Total Volume of Soil (cubic centimeters)Porosity % from direct measurement
