Explanation:

1 and 2 only

Statement 1 is correct. The leaf color chart (LCC) is used to determine the amount of nitrogen fertilizer in the most accurate manner. It is used as a tool to assess the nitrogen status of plants by visually comparing the color of leaves with standardized color charts.

Statement 2 is correct. The leaf color chart typically consists of a set of standardized color charts resembling the colors of the rainbow. These charts help in visually assessing the nitrogen status of plants based on leaf color.

Statement 3 is incorrect. While the greenness of the leaf can be an indicator of nitrogen content to some extent, it's not the sole determinant, and other factors may also influence leaf color.
