Crop Production Management (Manure, Fertilisers, Irrigation)Quiz - Solve & Score
Q1. A village farmer fills a pit with cattle dung, leftover straw and kitchen peelings and lets the heap rot for months before spreading it on the field; what is the product he spreads called?
- A.Pesticide
- B.Chemical fertiliser
- C.Weedicide
- D.Manure
Answer: D. Manure
Manure is decomposed organic matter from animal dung, urine and plant residues. Rotting farm waste in a pit yields manure, not a manufactured fertiliser.
Q2. A shopkeeper sells a sack labelled 'urea, 46% nitrogen' that was produced in a chemical plant; into which category of soil input does this sack belong?
- A.Inorganic fertiliser
- B.Compost
- C.Green manure
- D.Organic manure
Answer: A. Inorganic fertiliser
Urea is a synthetic nitrogenous compound made in factories, so it is an inorganic (chemical) fertiliser rather than a natural manure.

- A.Both of them equally
- B.Neither of them

- D.The fine white crystalline powder
Answer: C. The bulky dark crumbly material from the pit
Manure is decomposed organic waste and is typically bulky, dark and crumbly. The bagged crystalline powder is a concentrated chemical fertiliser.
