Do the right thing
The increasing desire for architects, engineers, planners, ecologists to incorporate soils in their approaches acknowledge the aboveground impacts of belowground conditions, is very positive and has potential to increase understanding of many ecological process and patterns. If these positive new approaches do not have at least a basic understanding of soil, the potential for making fundamental errors. And thus the risk of generating incorrect and unreliable information is high [1]. A soil contains life, is very reactive to chemical stress, normally compensates both chemical and physical stresses. If you apply a specific test developed for the asphalts [2], does the applicability of the results remain reliable? If you guess soil moisture by feeling and observing its appearance “As the soil approaches wilt point, it becomes lighter in color. If you’re unsure what the color should be when there is adequate moisture, add water to a small sample and compare it to the actual soil color” [3] sometimes you could falling into error. ...and if you think of increasing the culture on the soil suggesting questions like this “There are 6 major types of soil: Sandy, Clayey, Loamy, Silty, Chalky and Peaty [4]” maybe you will not get the desired result.
