These Visual Soil Assessment (VSA) indicators are morphological and measured soil characteristics that allow for the transfer of information between sites, soil types, land uses etc., while providing a cross check and physical reality to structure descriptors.

The major land degradation problems in Egypt are related to hydrological constraints which cause waterlogging, salinity and alkalinity, physical constraints such as deterioration of the soil structure and compaction, and biological constraints caused by a decline in soil organic matter leading to declining soil fertility.

Poor growth may occur due to high winds, climate, salt spray, infertile or toxic soil, or heavy exploitation by humans.

Definition A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.

The emission rate depends on a complex array of factors like soil structure, pH, temperature, type of crop, water saturation and nitrogen fertilizer.

In Sudan, IFAD has funded research into cash and forage crop varieties that are resistant to drought, salinity and poor soil conditions.

I said, Food without soil, how can we grow without soil?

Agricultural activity in Anguilla is limited due to a combination of factors, including poor soil, the small amount of arable land and irregular rainfall.

That's good soil.

Soil Soil erosion is fast becoming one of the worlds greatest problems.

24. Agricultural activity in Anguilla is extremely limited by a combination of factors, including poor soil, a small amount of arable land and irregular rainfall.

Instead, these policies have left hundreds of millions of people even more desperately poor and hungry, and even more vulnerable to drought, pests, and soil depletion.

Carnivorous plants have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs and rock outcroppings.

There is no soil.

We are the soil.

No water, rocky soil.

(e) New artificial materials for fertilizing the soil and holding moisture in sandy soil

Well, surprisingly enough, amazingly enough, the anatomists had a very poor idea of the structure of the lung until very recently.

Immediately north of the ancient port of Jaffa, Tel Aviv lies on land that used to be sand dunes and as such has relatively poor soil fertility.

43. Land is devoted almost entirely to sheep ranching no crops are grown and because of the strong winds and poor soil there are no indigenous trees.

Many concepts essential to understanding soil come from individuals not identifiable strictly as soil scientists.

They're still soil and water, you've just created a mixture of soil and water mud.

Then crack the soil open .

It scratches on the soil.

String Trimmer ... ... and Soil Pulverizer.

The soil is drying out.

He's returned to American soil?

Soil nutrients are being depleted, soil moisture is falling, temperatures are rising, and disease pressures are worsening.

It is one of the 30 major soil groups of the World Reference Base for Soil Resources.
