soil surface

The water table is at or near the soil surface for 6 to 9 months of the year.

The top rim should be level with the soil surface.

The groundwater level is always less than 5 feet below the soil surface.

This growth will break down the mulch that is left on the soil surface.

The tubers form close to the soil surface and sometimes even on top of the ground.

When planting, this crown should be set very near the soil surface.

Plants form a blanket of runners on the soil surface.

The soil surface should feel cool to the touch, barely damp.

Maple roots have a tradition of growing near the soil surface.

This often is buried just beneath the soil surface and may not be obvious.

The seeds are black, and germinate on the soil surface.

With this, comes the protection of a soils surface when rain is falling to the ground.

The process of infiltration can continue only if there is room available for additional water at the soil surface.

They move to the soil surface to begin feeding on roots and other organic matter.

During the day, they hide in debris at the soil surface near the base of the tree.

The larvae eat plant roots and other matter near the soil surface.

Other perennials put out runners that spread along the soil surface.

They mature below the soil surface or extend 2 cm above the ground.

The larvae feed on various herbs at the soil surface.

Plant carefully, making sure that the crown is about two inches below the soil surface.

"The soil surface was about 35 degrees lower in the middle of the day than under plastic mulch," he said.

They may also be found beneath the soil surface hunting for earthworms.

They tend to form at the sides of the parent plant and are most often located near the soil surface.

This stage of their life is important because the bulbs beneath the soil surface are not idle.

They lie on the soil surface waiting for prey.
