2. Calculate the CEC of two soils (prairie and forest) assuming that barium (Ba") acetate was used to replace all the cations on the soils exchange sites and the barium acetate was replaced with CaCi. If 5 gram of cach soil was used and the Ba" concentration in 250 ml (0.250 L) of the final extruct was found to be 400 mg BuL for the prairie soil and 240 mg BuL for the forest soil, caleulate the CEC for each soil.

Section 3: Aeration and Gas Transporta) How would you explain air-filled porosity for clayey soils being less than sandy soils?b) Briefly discuss why the composition of soil air is as relevant as determining the air-filled porosity inassessing soil aeration.c) The air-phase O2 concentration measured in the field was found to diminish linearly from 0.0003 gcm-3 at the soil surface to 0.000257 g cm-3 at the 0.6-m depth. The soil temperature was determined tobe same as the atmospheric air temperature of 25 oC. Soil core (volume = 0.64 litres) samples werecollected in the top 0.6 m of a soil profile to assess the soil’s ability to promote aeration and gastransport. The average total mass of the soil sample was determined as 1.0 kg. The samples were ovendried at 105 oC for 24 hours to obtain an average dry mass of 0.85 kg. Based on the given informationabout the soil:i) Determine the diffusive flux of O2 through the 0.6-m soil layer based on the soil diffusioncoefficient determined from the…

An inert chemical was applied to the soil surface 2 years ago. The Kd value of the chemical is 0.2 cm3 g-1 Assume the average drainage rate in the soil profile is 0.5 m per year, annual average water content of the soil is 0.2 cm3 cm-3, and bulk density is 1.25 g cm-3. Estimate where the chemical is in the soil profile now.
Your soil is 3.3% organic matter and 18.8% clay. Of that 18.8% clay, 20% is kaolinite, 20% is vermiculite, 40% is smectite, and 20% is mica. It is 1.7% iron oxide. Your soil is at a pH of 7. What is the total CEC of this soil in cmolc/kg? Please answer to one decimal.

In a partially saturated soil, the moisture content W% is 66.67%, the relative specific gravity of solids Ss is 2.5, and the saturated specific gravity of the sample is 1.45 g/cm3. If the volume of air is equal to 8 cm3. Determine the other quantities of the scheme, and calculate: e, n, Gw%, Ym, Yd, Ysat, Y'. Note: Kindly answer all with clear calculations.
The weight of a chunk of moist soil is 208 g and the volume of the sil chunkmeasured before drying is 120 cubic cm. After being dried out in the oven, the weight of the dry soil is 170 grams. Use Gs=2.65a. Compute the water content of the soil.b. Compute the void ratio.c. Compute the degree of saturation.
The in situ moisture content of a soil is 18%, and the wet specific gravity is 17.5 kN/m3. The weight relative specificity of soil solids is 2.72. The soil must be excavated and transported to a construction site for use in a compacted landfill. If the specifications require that the soil is compacted with a specific compacted weight of “d comp” (see Table 1) and with the same 18% moisture content. Calculate how many cubic meters of soil must be removed from the borrow area to build a “V comp” volume compacted landfill (see Table 1). calculate also what would be the mass of water (in tons) that must be added to reach a humidity optimum of 23%.
A sample of inorganic soil has 100% passing the No. 4 sieve and 75% passing the No. 200 sieve. The liquid limit for the soil was found to be 60 %, while the plasticity index was 24%. Classify this soil according to the USCS.
