soil layer

The gas pressure also supports the soil layers above the field.

They stay near the upper soil layer because all the main nutrients are found there.

So in almost any weather conditions, there is a great danger of not being able to see and record soil layers properly.

Soil layers usually get older the deeper they go.

But as the soil layer thickens, this process is slowed down.

Water filters through soil layers before entering the groundwater system.

The well filter must be placed in a permeable soil layer.

The removal of material from a soil layer is called eluviation.

Drip irrigation lines, used only when needed, snake beneath the soil layer.

Despite the dry surface and upper soil layers, there are several water sources that pour deep directly into the sea.

The hara seeds become fixed in the soil layers of the sea and grow.

He said a septic system would be located in an area with a thick soil layer to protect groundwater.

The majority are tunnelers, burrowing through the snow and surface soil layers.

They may also be used to transfer building loads past weak or compressible soil layers.

This process leads to marked contrasts in the appearance and chemistry of the soil layers.

The carbon dioxide would have been compressed and pumped underground into deep soil layers.

See how the soil layers change color?

The roots of the plant are within the shallow soil layer with some anchoring in rock fractures.

It is considered unfeasible to determine the geotechnical characteristics of this soil layer.

The overlying soil layer is gradually lifted up by frost heaving.

The archaeological site comprises 10 different soil layers.

Mainly smaller trees, the soil layer being thin).

Builders of the object cut off a soil layer up to virgin clay, and placed stones into this trench.

Some roots are commonly found in organic soil layers or near the mineral soil surface.

He soon noticed the phenomenon referred to as hardpan (the creation of a water resistant soil layer).
