Which of the following statements is true about chemical fertilisers?

• A. They are insoluble in water.
• B. They provide organic matter to the soil.
• C. Overuse of chemical fertilisers make soil fertile.
• D. They are nutrient specific.

Answer 1

The correct option is D They are nutrient specific.

Chemical fertilizer is a chemically synthesized substance used to provide nutrients to the plants. They are nutrient specific such as NPK only for nitrogen, phosphorus, and potassium. They are water soluble and hence easily absorbed by plants. But its overuse can harm the soil fertility and can also involve food chain.
