Statement 1 is correct while statement 2 is not correct: The rising global demand for food has led to the widespread use of fertilizers. While conventional chemical fertilizers enhance plant growth and yield, they also negatively impact soil health, the environment, and human well-being. As a result, nanofertilizers have emerged as a promising alternative. These advanced materials consist of nanoparticles containing essential macro- and micronutrients, which are released in a controlled manner to the plant rhizosphere. In nanofertilizers, vital nutrients such as nitrogen (N), phosphorus (P), potassium (K), iron (Fe), and manganese (Mn) are either individually bonded or combined with nano-sized adsorbents.

Statement 3 is not correct: Unlike traditional fertilizers, nanofertilizers utilize nanoparticles to regulate nutrient release, improving efficiency and reducing costs. They contain one or more plant nutrients, with at least 50% of the particles measuring less than 100 nanometers in size.
