,
, The difference in magnitude is exponential between single PH readings. Therefore, a difference of 1 is
equivalent to 101 = 10. For 7 to 4, the difference is 3 and the magnitude of difference becomes 103 =
1000.
What is not a detrimental impact on tree growth from compaction?
(A) Restricted root growth
(B) Reduction of water availability (C) Increasing organic material (D) Restricting air movement The
answer is (C)
Compacted soils decrease the total pore space which will limit the amount of air and water that can be
present. Naturally, this has a detrimental effect on facilitating tree growth by effecting roots growth and
absorption. It does not have an impact on the makeup of the soil itself.
Field capacity is achieved after the draining of which of the following?
(A) Gravitational water (B) Capillary water
(C) Micropore water
(D) Compacted drainage The answer is (A)
Filed capacity is the condition after all of the water has drained due to gravity.
What best defines the permanent wilting point soil moisture condition?
(A) Water is present in macro and micropores
(B) The condition present immediately after the removal of gravitational water (C) Water is held by soil
and unavailable to plants such that they can't recover (D) No water present in soil The answer is
(C)
Water needs to be available for uptake. If not, the tree will begin to feel the stress of dehydration and
wilting will begin to occur. If the lack of water persists over a sufficient amount of time, the tree will not
be able to recover and has reached the permanent wilting point.
The ideal soil ratio for solids to pore space is:
(A) 20:80
(B) 35:65
(C) 40:60
(D) 50:50 The answer is (D)
, An even split between the amount of solids and the amount of pore space is the ideal condition. This
allows the pore space to contain sufficient amounts of water and air while maintaining the soil integrity.
The solids ideally are 45% mineral and 5% organic matter.
What is the correct scientific name for the oak tree genus?
(A) Quercus (B) Pyrus (C) Larix (D) Acer The answer is (A)
Which of the following is not one of the five major categories of soil horizons?
(A) O (B) E (C) N (D) B The answer is (C)
The five major categories of soil horizons consist of O, E, A, B, and C
Loam is least composed of what soil classification?
(A) Sand
(B) Silt
(C) Clay
(D) Bedrock The answer is (C)
Loam is a combination of all three soil types sand, silt, and clay. However, loam without any specific
designation is not equally composed of all three but rather has the least amount of clay.
What is the difference in magnitude of acidity between a PH level reading of 4 vs. a PH reading of 7?
(A) 1
(B) 3
(C) 100 (D) 1000 The answer is (D)
What soil below most likely has the lowest infiltration rate?
(A) Loose sand
(B) Compacted sand (C) Loose clay
(D) Compacted clay The answer is (D)
