Topsoil refers to the soil making up the top layer of the soil.

• True

• False

The texture of the soil influences the available pore space in a soil

• True

• False

Water movement is not dependent on the type of soil

• True

• False

Organic matter is any carbon-containing material in the soil

• True

• False

Soil pH is defined as the amount of oxygen ions in the soil solution

• True

• False

Which of the following is not true about having good soil structure:

• Soils are easier to till

• Plant roots are able to penetrate the soil easier

• Good structure reduces the amount of large pore space in the soil

• Good structure improves water movement though the soil

Which of the following is not true of nitrogen:

• Can leach out of the soil easily

• Is needed everywhere in the plant

• Deficiency symptoms show up first on the newer leaves

• It is recommended to split up nitrogen applications to get the most benefits

When the soil pH is too high (too alkaline):

• The soil must be excavated and new soil brought in

• Sulfur or sulfate compound can be added to lower the pH

• The soil needs to be limed

• Plants can no longer be grown in the soil

Bushes turning yellow or trees showing a yellow striping pattern on their leaves can be an indication that:

• The plants are suffering from a micro-nutrient deficiency due to high soil pH

• The plants are old and need to be replaced

• Stray beams from the atmosphere are zapping the trees and shrubs

• The soil needs to be limed

Which of the following is a benefit of soil testing:

• Helps monitor the nutrient status of the soil

• Saves money by pinpointing the nutrients needed by the soil

• Increases yield or quality of the plants by providing optimum conditions for their growth

• Alerts you to possible problems before they show up in the plants, thus providing the opportunity to correct before they become serious

• All of the above
