Solution
The correct option is D Both A and B
- 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.
