Ignition of manure is possible if__________________

  1. Stored in a very large pile

  2. Stored in small piles

  3. Stored near fodder

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Manure is an organic substance produced by the decomposition of plant and animal wastes in the presence of microorganism and used as fertilizers. Thus, the fresh manure contains decomposing bacteria along with active digestive enzymes. These enzymes contribute to the faster heating of the manure which accelerates the decomposition of organic materials by the soil microorganisms. Manure generates heat as it decomposes, and it is possible for manure to ignite spontaneously if stored in a very large pile. 

Therefore, the correct answer is option A.

Fertilizers can cause _________________

  1. Burn in plants

  2. Burn in microorganism

  3. Burn in soil

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Fertilizer can cause burn in the plants when too much fertilizer is applied. It is a chemical compound that can dry out the leaves and damage or even cause the death of the plant. 
  • Fertilizers vary in their tendency to burn roughly in accordance with their salt index. 

Therefore, the correct answer is option A.

The unpleasant odor of manure can be prevented by____________

  1. Adding water to it

  2. By using it fresh

  3. Both A and B

  4. By injecting it in the soil
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Manure is an organic substance produced by the decomposition of plant and animal wastes in the presence of microorganisms and thus, produces an unpleasant odor. 
  • To prevent such odor they are usually knifed (injected) directly into the soil. Manure from pig and cattle is usually spread on fields using a manure spreader. 

Therefore, the correct answer is option D.

Fertilizers can be classified as__________________

  1. Straight and multinutrient

  2. Inorganic and organic

  3. Synthetic and Inorganic

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Fertilizers, chemically synthesized substances that are rich in plant nutrients such as NPK. They are artificially made but have a rapid response. Overuse of fertilizers can cause negative effects such as decreased soil fertility.
  • Fertilizers are classified according to whether they provide a single nutrient (say, N, P, or K), in which case they are classified as straight fertilizers. Multinutrient fertilizers (or complex fertilizers) provide two or more nutrients e.g., N and P. 
  • Fertilizers are also sometimes classified as inorganic and organic on the basis of molecular structure. Organic fertilizers are derived from plant or animal sources, whereas inorganic fertilizers contain minerals and synthetic chemicals.
  • Therefore, the correct answer is option D.

Find out the correct sentence about manure.
i) Manure contains large quantities of organic matter and small quantities of nutrients.
(ii) It increases the water holding capacity of sandy soil.
(iii) It helps in draining out of the excess of water from the clayey soil.
(iv) Its excessive use pollutes the environment because it is made of animal excretory waste.

  1. (i) and (iii)

  2. (i) and (ii)

  3. (ii) and (iii)

  4. (iii) and (iv)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bulky organic manure contains large quantities of organic matter and small quantities of nutrients. It increases the water holding capacity of sandy soil. This makes more water available to plants. It prevents the environment pollution, because it recycles the animal excretory waste. Therefore, option B is correct.

Why is vivipary an undesirable character for annual crop plants?

  1. It reduces vigour of the plant

  2. It adversely affects the fertility of the plant

  3. The seeds exhibit long dormancy

  4. The seeds connot be stored under normal conditions for next season
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Vivipary is the germination of seeds while still attached to the parent plant. In annual crops, this is undesirable because it prevents the normal dormancy period required for storage and handling, making the seeds difficult to manage for the next season.
