Sand vs. Soil for Propagation
· Plants that are easy to root (like forsythia, caryopteris, coleus, etc.) will do fine in soil but more difficult rooting specimens may simply rot in soil as opposed to vermiculite or sand as a medium. Peat can be used mixed together with either sand, perlit, or vermiculite and it maintains sterility due to its high acid content.

Effects of Sediment on the Aquatic Environment: | NRCS
Lake trout, like stream trout, cannot successfully spawn in areas that are blanketed with fine sediments (Nester and Poe 1987). Other lake species prefer sand, rocks, inshore environments, logs, sticks, plants, or vegetative nests (Herdendorf 1992). Lag cobbles or gravels are often used for spawning while modern deposits may be avoided.

Keeping soil in its place – Soils Matter, Get the Scoop!
· Erosion is a natural process; it is the reason we have valleys, mesas, sand dunes, and the Grand Canyon. There are three processes in erosion: 1) Detachment of soil particles from the surface. 2) Transportation of the detached particles. 3) Deposition of the particles. Erosion control methods address one or more of these processes.
