The Oedometer test takes 5days to complete. A sample is placed in the Oedometer and loads are applied to the sample. The settlement is then recorded over a period of time. Since no lateral deformation takes place only one dimension is obtained.
On the first day the Oedometer was set up and our sample was placed in the oedometer cell after the size and moisture content (%) was determined. Weights were placed on the arm and the settlement was recorded after an hour. On the second day, after 24hour, the settlement is recorded again and more weight is placed onto the lever arm. This is repeated two more times on 48 and 72hours. On the last day we recorded the rebound and measured the diameter and the final moisture content of our sample.

Silt is the only soil separate that feels like flour, so "b" is the sample highest in silt. Stickiness is a property of clay, as is high plasticity. Grittiness is a term used to describe sandy soils.
How nitrogen in soil is detected?
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
How do you test moisture level in soil?
A test for soil moisture is to:1. weigh a brown paper bag2. add a sample of your soil to that bag3. weigh the total weight of the bag plus the soil4. put the bag of soil in an oven for 24 hours at 200 degrees5. reweigh the bagsubtract the final/dry weight of the bag from the initial soil bag weight and that number will be the weight of moisture that has left the soil.
Which conditions must be met to conduct a test for the difference in two sample means?
The two samples must be independent and the data must be at least ordinal. Under those conditions the Mann-Whitney U test can be used.
