Question

When water potential will have maximum absorbing capacity?

Answer 1

Water Holding Capacity. ... In general, the higher the percentage of silt and clay sized particles, the higher the water holdingcapacity. The small particles (clay and silt)have a much larger surface area than the larger sand particles. This large surface area allows the soil to hold a greater quantity of water.

Answer 2

Water potential is the potential energy of water in a system compared to pure water, when both temperature and pressure are kept the same. It can also be described as a measure of how freely water molecules can move in a particular environment or system. It is measured in kilopascals (kPa) and is represented by the Greek letter Psi (Ψ). Water potential is never positive but has a maximum value of zero, which is that of pure water at atmospheric pressure. When it comes to impure water, or water that has solutes in it, the more solute there is, the more negative Ψ becomes, since the solute molecules will attract the water molecules and restrict their freedom to move.
