What are some reasons to name soil as brown gold?

We name different things as colored gold to show and note on high values of them. Why not we call the soil as brown gold because of many services to human life?

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Morteza: Freeze-thaw cycle enhances erosion of soil, generating colloids or fine particles that can be transported in overland flow (see: http://www.sciencedirect.com/science/article/pii/S0169555X99000926) or infiltrated into soil (see: http://pubs.acs.org/doi/abs/10.1021/es403698u). If you don't have access to full text of these articles, let me know.

Morteza: My experience shows that freeze/thaw can either increase or decrease aggregate stability, and therefore likely the sediment yield and runoff generation. I've found the thawing conditions are probably the most important in determining the effect. Please see some of my research on my profile.
