At both locations A and B, samples were collected and tested for C/N ratio X and Y respectively. Location A witness the liberation of ammonia gas and location B witnessed the incomplete digestion of Organic Matter. Which of the following is true?
1
X < 45 and Y > 45
2
X < 45 and Y < 45
3
X ≥ 45 and Y > 45
4
X > 45 and Y ≤ 45.
