In short. The general theory, of good or suitable loam is this. Take a handful of soli/loam etc. Squeeze it gently, release the presure. The content should remain somewaht compact. In scientific reality this holds fast to the fact that the substance contains sufficient moisture so enabling it to temororarily bond together. In reallity most compounds will do this. It relies upon a fomulae of mass plus moisture etc. However when considering the benefits of soil, dirt earth or whatever you wish to call it. For the pupose of growing plants in it, more is required. Here we enter the area of pH. This is a scientific grading of acidity and alkalinity values. Often rough soil will over time be affected by natural elements etc and thus become viable planting media for various subjects. I'd best leave it there.
