Soil Ph

The pH scale is a range from:

• 1-7
• 0-14
• 1-5
• 1-20

Soil pH is important because

• it determines a soil's suitability for life

• it determines whether nutrient elements are at optimal, deficient, or toxic levels

• it determines the fate of soil pollution

• all answers are correct

What is the pH range which provides for the optimal availability of plant essential nutrients (elements)?

• 12.3-14.2

• 6.3-7.2

• 2.3-3.3

• none of the answers are correct

Only pH testing equipment can be used to test for the pH of soil

• true

• false

If you find a plot of land to not be in optimal pH level, you should find another plot of land more suitable since nothing can be done to correct it

• true

• false

Bacteria ONLY live in neutral pH levels which ultimately help those neutral plants obtain nutrients from soil

• true

• false

If we find today that the soil is too acidic (below 4.5), how might that affect the number of species we find?

• We may find a lot MORE species as most plants like acidic soil.

• We may find a lot LESS species as most plants like very basic soil.

• We may find LESS species as most plants will not grow well since they won't have the nutrients to grow and reproduce in very acidic soil.

• There should be no measurable effect.
