Question
1. which of this information is NOT available in a County Soil Survey?
A. Engineering properties of soil
B. Agricultural potential of soil
C. Physical and Chemical properties of soil
D. None of the above
2. According to Dukuchaev soils formed under similar climate are refferred to as:
A. Intrazonal soils B. Azonal soils C. Zonal Soils D. Interzonal Soil E. Climosequence
3.Which of these statements is not correct about the effect of aspect on soil properties differentiation?
A. The effects of aspects is more pronounced in higher latitudes than lower latitudes.
B. in higher latitudes, organic matter is higher on the north facing slope
C. in higher latitudes, the soil profile is thicker on noth facing slopes
D. in higher latitudes, soil texture tends to be finer on north facing slopes
E. none of the above.
4. Which of these statments is not true about the effect of topography?
A. the level of organic matter is higher on the lower slope position. C. soil moisture is lower on the upper slope position
B. the soil solum is thicker in the lower slope position D. soil color is darker in lower slope position E. none of the above
5. According to Hans Jenny which of these factors is the most important in the process of soil formation?
A. Parent material B. climate C. Organism D. Relief and time E. All are of equal importance
6. which of these statements about the soil profile is not correct?
A. The solum is the genetically altered part of the profile B. the profile includes the solum and the weathered regolith
C. the profile consists of several horizons D. The profile is a product of weathered and alteration by microorganisms
E. the solum consist of unwheathered parent material
Explanation / Answer
1. d. None of the above.. All the information is provided in options a,b,c areobtained from the soil survey. SOil survey refers to the study of properties of the soil and suitably classifying them according to their organic content, agricultural potential, properties- physical, chemical and engineering.
2. A. Intrazonal soils are formed under similar climatic conditions.
3. Aspect of a slope is the direction of the slope.
4. e. none of the above are incorrect. All the points from a to d are correct.
5. e. all the above factors. Parent material, climate, organism, relief and time all are equal in the formation of a soil
6. A. Solumos the genetically altered part of the profile- this statement is not correct. This is becase solum formation is attributed to the same pedogenic processes. All the other factors are correct about solum.
