Ok, so crazy pointing Edge and I conversed a bit and we thought about what would make people go to sleep. I said reading bio. He said an increase in the hormone dopamine. So I decided to show you what I do all the time:
BIO:
Graphic relationship of soil water potential vs. water content (%). Take-home lessons
between PWP and FC is the water available for a plant to use;
clay holds more water than sand at any Y ; and
clay holds water more tightly (i.e., @10% water Ysand > Yclay). This is essentially a s/v problem, since smaller particles in clay they have a larger total surface and hence, has more charged surfaces that will bind water tightly.
Soil water potential is a function of osmotic potential (which is usually near zero except in saline soils) and mostly pressure (used to call it matrix potential; this refers to the tension generated because of the attraction of colloidal particles; i.e., adhesion). The pressure in the soil can be calculated from the equation: Yp = -2T/r where T = surface tension (7.28 x 10-8 MPa) and r = radius of curvature of the meniscus). Water movement through soil - mostly due to bulk flow as a result of pressure gradients, with some diffusion.
History: Technology: America?s patent system made people want to invent practical items to make money. Since if it was patented, others couldn?t make money from it, inventors created new items all the time. Factories became prevalent after the 1820s when they began to establish themselves as good ways to create revenue. Unions were formed as early as 1790, but as the times progressed, their enemies were fighting immigrants who would work for cheap, states outlawing unions, and economic depressions that caused unemployment.
