CSES 2040 – Exam 1 Review: Soil Science Concepts & Practice Questions | 2025/26 UPDATES.
VERIFIED.
About This Resource:
This CSES 2040 Exam 1 Study Guide is designed for students taking their first major exam in Crop, Soil,
and Environmental Sciences. It includes essential coverage of soil formation, structure, nutrient cycles,
water movement, and soil chemistry, as well as practice questions, diagrams, and summaries to
reinforce key concepts. Ideal for quick review or in-depth prep!
____________ deficiency in local soils will cause Keshan disease. - ✔✔-Se
_______an area of land drained by a single system of stre
ams and bounded by ridges that separate it from adjust areas. - ✔✔-watershed
_______is a regulatory term in the U.
S. Clean Water Act, describing a plan for restoring impaired waters that
identifies the maximum amount of a pollutant that
a body of water can receive wh
ile still meeting water quality
standards. - ✔✔-TMDL
A and B are subsamples of the same soil. They are treated with different solute concentrations that is
expressed in millimoles/L (mM) (i.e the higher the mM, the more concentrated the solution is) and placed
intact.
For the above condition, water will more likely flow from soil sample A to B if:
a. A = 15 mM, B = 10 mM
b. A = 25 mM, B = 10 mM
c. A = 40 mM, B = 30 mM
d. None of the above - ✔✔-d. None of the above
, A and B are subsamples of the same soil. They are treated with different solute concentrations that is
expressed in millimoles/L (mM) (i.e the higher the mM, the more concentrated the solution is) and placed
intact. Solute will more likely move from sample A to soil B if their concentration expressed in (mM) is:
a. A = 15 mM, B = 10 mM
b. A = 25 mM, B = 10 mM
c. A = 40 mM, B = 30 mM
d. All of the above - ✔✔-d. All of the above
A constructed golf course soil prof
ile will have sand on the top horizon
and gravel below it. This to: - ✔✔-decrease/retard downward movement of water.
A given soil has 10% sand, 30% silt and 5%
organic matter. Its clay content will be: - ✔✔-60%
A given soil has a nomenclature of Miami silt loam, fine loamy, mixed, mesic, Typic Argiaquoll. What is
the order name of this soil? - ✔✔-Mollisol
A given soil has a nomenclature of Miami silt loam, fine loamy, mixed, mesic, Typic Argiaquoll. What is
the subgroup name of this soil? - ✔✔-Typic Argiaquoll
A prime land that is most suitable for agriculture with little or no limitation has a land capability
classification of: - ✔✔-I
A soil analysis data indicates 60% sand, 20% clay, and 2% organic matter as determined by the AU Soil
Testing lab. The percentage of silt in this soil is: - ✔✔-20
A soil horizon has ______ master horizons - ✔✔-6
A soil is an interface of air, water, biota, and solid particles and accordingly called: - ✔✔-Pedosphere
