The soil as a fractal object

The concept for Fractal permanently entered the science during the second half of 20th century. The fractal geometry is antipode of the Euclidian geometry of the smooth figures with integer dimension ( 1 for lines, 2 for surfaces, 3 for volumes etc.). However, the real surrounding world is not ideal as the Euclidian one: the Earth is a globe but its surface is not smooth ( oceans, continents, mountains); the soils are not dense as the water, oil etc. are. They have pores of different size. In other words, they represent fractal structures with non-integer ( fractal) dimension D. Here we introduce the notion of fractal, so far unused in our agricultural studies. We describe a virtual experiment in two versions, by which one can determine the fractal dimension D, of different soils. As generalized characteristics of the soil structure, D can be used for practical and other purpose in the soil science.
