Forestry Exam 2 ACTUAL Exam
Questions and CORRECT Answers
soil - CORRECT ANSWER - a dynamic natural body on the surface of the earth in which
plants grow, is composed of air, water, minerals, and organic matter interacting with living
organisms and is a product of climate and vegetation
4 concepts of soil - CORRECT ANSWER - 1. medium for plant growth
2. a natural body with physical, chemical, and biological properties of 5 soil forming factors
3. vegetated, water transmitting mantle
4. component of the forest ecosystem
soil horizon - CORRECT ANSWER - a distinct layer within a soil profile
soil profile - CORRECT ANSWER - All the vertical layers or horizons that make up a soil
in a particular place
0-layer - CORRECT ANSWER - layer of organic matter
A- layer - CORRECT ANSWER - mineral horizon mixed with the o horizon "top soil"
B- layer - CORRECT ANSWER - contains silicate clays; such as Fe and Al
E- layer - CORRECT ANSWER - the mineral horizon that has lost silicon
C- layer - CORRECT ANSWER - very little effect from soil forming processes lacks all of
the properties from the above horizons
R- layer - CORRECT ANSWER - bed rock
, physical soil properties - CORRECT ANSWER - color, texture, and structure
soil color - CORRECT ANSWER - dependent on the mineral composition, organic matter
content, and soil drainage class
texture - CORRECT ANSWER - refers to the relative proportions of the carious mineral
particles (influences structure)
why is determining a forest's soil texture important to before replanting? - CORRECT
ANSWER - understanding what type of soil you are dealing with can help you match you
match your species to it so that you can be more successful.
soil structure - CORRECT ANSWER - combination or arrangement of primary soil
particles into peds (plays a role in drainage)
peds - CORRECT ANSWER - secondary soil particles
litter - CORRECT ANSWER - little decomposition, freshly cut grass or leaves, top layer
humus - CORRECT ANSWER - a dark mass of complex amorphous organic material (by
products of litter)
soil water - CORRECT ANSWER - influences the distribution and growth
acts as a solvent for transportation of nutrients
available water - CORRECT ANSWER - is water that the plant can get from the soil
transpiration - CORRECT ANSWER - loss of water through leaves
