It is certainly B as ashes of any organic matter makes soil fertile.

Ans 2:

Class : Class 6
Come on Snigdha! The CORRECT ANSWER IS (B)! Ash makes soil fertile 'cause it's organic , dude! How will trees not grow?(P.S.- please don't think about Ash in Pokemon. Please, don't)🤦‍♂️🤦‍♂️

Ans 3:

I think B is correct option as ash acts as a fertilizer for plants (even if in small quantities). Master Answer (Admin, Revisewise) EXPLAIN the answer to all of us.

Ans 4:

Class : Class 8
B IS THE CORRECT ANSWER AS BURNING OF WASTE CROPS AFTER HARVESTING OF GRAINS IS STANDARD METHOD OF INCREASING SOIL FERTILITY

Ans 5:

Class : Class 9

Ans 6:

Class : Class 5

Ans 7:

Class : Class 7
THe AntwerpThe answer is (A) because if forest fire occurs there will not be any trees and soil erosion can happen and All the ashes including soil may erode and then how can it make the soil fertile

i think the answer should be B because the statement 'New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile' is also true

Ans 12:

Class : Class 5
B B B B B B . B B B B B B BB BB B B B B B . IS THE ANSWER

Ans 34:

Class : Class 5
The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.

Ans 35:

Class : Class 9
I think the answer is B

Ans 36:

Class : Class 7
BBBB IS THE ANSWER

Ans 37:

Class : Class 6
I think the answer should be b as after a forest gets destroyed by a forest fire ,new trees will grow as the remain of the trees will decompose and make the sol fertile.

Ans 38:

Class : Class 8
a is correct because there willbe soil erosion without trees

If my answer is correct then please, please, please comment on it. My goal here is not to give long lectures, but to find the correct answer to this question.
