584 Questions

Soil and foundation engineering questions address the physical and mechanical properties of soil critical for construction and stability. The topics include shear strength, soil compaction, void ratios, and subsurface investigation techniques. These advanced geotechnical concepts are typically evaluated in civil engineering and specialized recruitment examinations.

Well-Grown potting soil is made from only peat moss and compost in a ratio of $3$ pounds of peat moss to $5$ pounds of compost. If a bag of Well-Grown potting soil contains $12$ pounds of potting soil, find how many pounds of peat moss it contains.

  1. $4.18$
  2. $4.22$
  3. $4.35$
  4. $4.50$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$3$ pounds of peat moss is to $5$ pounds of compost is the composition in $8$ pounds potting soil.

Since we have $12$ pounds of potting soil, corresponding amount of peat moss becomes $\cfrac{3 \times 12}{8} = 4.5 $ pounds

Good soil is

  1. Which holds whole of the water that enters into it

  2. Which allows percolating the water slowly from it

  3. Which allows water to pass very quickly from it

  4. Which allows limited amount of water to retain into it
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water should percolate slowly in a soil because if water passes too rapidly, then many of the minerals and organic matter useful for plants will simply be washed away. If there is no percolation and all the water is simply held up in the soil, then there will be poor aeration and respiration in plant roots will suffer.

Multiple choice business organisation and correspondence waste and its management sources of waste protecting our environment rules are for everyone

The relationship among different types of soil water can be summed up by the following equations. Which one is correct?

  1. Chresard = echard + hollard

  2. Chresard = hollard - echard

  3. Echard = hollard + chresard

  4. Hollard = chresard - echard
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants require water for the metabolic actions which is absorbed by the roots of the plants. The total water which is poured in the soil is not available to the plants.bThe total water content present in the soil is called hollard. Chresard is 75% of capillary water, water actually available for plants so that they can absorbed for their growth. Echard is remaining water. Therefore, correct relationship between them is Chresard + Echard = Hollard or Chresard = Hollard - echard. Thus, the correct answer is option B.

Multiple choice evs mud and stones soil - formation and profile soil-nature soil profile

Good soil is

  1. Which allows the limited amount of water into it

  2. Which allows to percolate the water slowly from it

  3. Which allows to pass water very quickly from it

  4. Which holds whole of water into it
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A good soil needs to be deep, fine-textured, moist, free-draining, loamy, and have an organic-rich topsoil. These properties best enable plant roots to take up nutrients, water and oxygen, and get enough support for rapid growth. In clay soils with small pore spaces, water moves slowly and spreads outward from where it is applied due to capillary action. In sandy soil, irrigation water can penetrate to 72 inches below the surface within 24 hours of application. In soils with a heavy clay content, water only penetrates to roughly 36 inches in 24 hours.

Therefore, the correct answer is option B.

Multiple choice evs mud and stones soil - formation and profile soil-nature soil profile

Column I represent the size of the soil particles and Column II
represents type of solid components. Which of the following is
correct match for the Column I and Column II.

Column I Column II
A. 0.2 to 2.00mm (i) Slit
B. Less than 0.002 mm (ii) Clay
C. 0.02 to 0.2 mm (iii) Coarse and particle
D. 0.002 to 0.02 mm (iv) Fine sand particle



  1. (A) - (ii), (B) - (iii), (C) - (iv), (D) - (i)

  2. (A) - (iv), (B) - (i), (C) - (iii) , (D) - (ii)

  3. (A) - (iii) , (B) - (ii) , (C)-(iv), (D) - (i)

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The texture of soil is determined by the proportions of particles of different sizes. Coarse sand particles are of 0.2 to 2.00 mm in size; 0.02 to 0.2 mm particles constitute fine sand; 0.002 to 0.02 particles represent silt and particles smaller than 0.002 mm are called clay.




Multiple choice biology modern agriculture modern equipments in agriculture soil quality methods of crop production

Which of the following does not affect the draft of ploughs? 

  1. Width of furrow

  2. Depth of furrow

  3. Length of furrow

  4. Soil moisture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plough is a tool which is used by the farmers for cultivation of the soil, planting for the sowing of seeds and turning over the soil and cut furrows. The tool is pulled through the ground in order to prepare furrows on the land. Draft of the plow does not affect the length of furrows. 

So, the correct option is 'Length of furrow'.

Multiple choice biology soil : our life soil properties soil - properties basics of soil pollution

A good soil is that which 

  1. Holds whole of the water entering into it

  2. Allows limited amount of water into it

  3. Allows the water to percolate slowly into it

  4. Allows the water to pass very quickly from it
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A good soil is that which allows the water to percolate slowly into groundwater. These soils can remove pollutants and they promote the growth of healthy vegetation, which in turn reduces soil erosion. 

Therefore, the correct answer is option C.
