Question

Fertilizers and manures contain plant nutrients such as:

• A. Nitrogen
• B. Potassium
• C. Phosphorous
• D. All of the above

Answer 1

Answer: (D)

All of the above

A plant requires nutrients for its growth and development. The nutrients are absorbed through the soil. The nutrient-supplying sources are manures and fertilizers. The application of manures and fertilizers to the soil is one of the important factors that help in increasing crop yield and maintaining soil fertility. Nitrogen, phosphorous, and potassium are the three major elements required for crop growth.

Therefore, the correct answer is option D.
