Waterlogging

• Salt in the soil that limits plant growth

• When soil gets so flooded with water, and the water then evaporates but the salt is left behind. After many years of this, the land is so salty that most plants can't grow.

• Intentionally starting a fire in a forest to allow the brush and the dead trees to be burned and the larger tree to not be destroyed.

• Planting crops without tilling or churning the soil, before you plant.

Slash-and-burn farming-

• An agricultural method for taking wild land such as a forest, and clearing it to grow crops. Usually this method involves slashing (cutting down) and burning the plants that were found there and planting a crop.

• The rock and soil found above a mine that must be removed to get to the mineral resource.

• Intentionally starting a fire in a forest to allow the brush and dead trees to be burned and the larger to not be destroyed.

• The ability of water to move through the soil and perhaps into an aquifer.
