Consider the following statements: The nation-wide 'Soil Health Card Scheme' aims at 1. expanding the cultivable area under irrigation. 2. enabling the banks to assess the quantum of loans to be granted to farmers on the basis of soil quality. 3. checking the overuse of fertilizers in farmlands. Which of the above statements is/are correct?

1. Statement 1 is incorrect. The 'Soil Health Card Scheme' focuses on analyzing the soil quality of farmers' farmlands to provide information on nutrient status and recommend appropriate dosage of fertilizers. It does not directly aim at expanding the cultivable area under irrigation. 2. Statement 2 is incorrect. While soil quality might be a factor in overall farm productivity, the Scheme's primary purpose is not to enable banks to assess the quantum of loans. Loan assessment typically involves other factors like land ownership, credit history, and projected income. 3. Statement 3 is correct. A key objective of the 'Soil Health Card Scheme' is to promote balanced fertilization based on soil tests. By providing farmers with specific recommendations for nutrient management, it aims at checking the overuse of fertilizers (especially nitrogenous ones like Urea), leading to improved soil health, reduced cultivation costs, and minimized environmental impact. 4. Therefore, only statement 3 correctly describes an aim of the scheme.
