Soil Science Objective Questions – 02

1. Which one is more harmful soil erosion?

(A) Natural Erosion

(B) Accelerate

(C) A & B Both

(D) None of Theses

(B) Accelerate: The process of soil erosion caused or accelerated by human activities is known as accelerated soil erosion. Natural erosion, on the other hand, occurs slowly over time owing to natural forces such as wind and rain.


2. How much time take in one inch soil formation?

(A) 100-120 Years

(B) 800-1000 Years

(C) 10000 Years

(D) 100000 Years

(B) 800-1000 Years


3. Maximum Water Erosion found in which state?

(A) Rajasthan

(B) Kerala

(C) West Bengal

(D) Madhya Pradesh

(C) West Bengal


4. Maximum Wind Erosion found in which state?

(A) Rajasthan

(B) Kerala

(C) West Bengal

(D) Madhya Pradesh

(A) Rajasthan


5. Dangerous phase of water erosion is:

(A) Splash Erosion

(B) Sheet Erosion

(C) Rill Erosion

(D) Slip Erosion/Gully Erosion

(D) Slip Erosion/Gully Erosion: Slip erosion, also known as gully erosion, is a type of soil erosion caused by concentrated runoff water cutting through the soil and forming a gully. Gullies can range in depth and width from a few inches to many feet. They can form on any slope, but they are most common on steep, poorly drained slopes.


6. In which type of soil acidity H+ ions observed by soil particle?

(A) Active Acidity

(B) Abosorve Acidity/Exchangeable Acidity

(C) Residual Acidity

(D) All of theses

(B) Abosorve Acidity/Exchangeable Acidity: Absorbed acidity, also known as exchangeable acidity, is a measure of the hydrogen and aluminium ions adsorbed on soil colloids. Soil colloids are small clay and organic matter particles in the soil with a significant surface area.


7. Maximum acid nature fertilizer is:

(A) Ammonium Nitrate

(B) Ammonium Sulphate

(C) Calcium Nitrate

(D) Calcium Ammonium Nitrate

(B) Ammonium Sulphate: Ammonium sulphate is a highly acidic nitrogen fertilizer. Ammonium sulphate has a nitrogen content of 21% and a sulphur content of 24%.


8. Should seed rate more in saline and alkaline soil?

(A) 10-15%

(B) 15-20%

(C) 25-30%

(D) 35-40%
