Leaf nitrogen estimation in potato based on spectral data and on simulated bands of the VENμS satellite Academic Article uri icon

abstract

  • Abstract Relationships between leaf spectral reflectance at 400–900 nm and nitrogen levels in potato petioles and leaves were studied. Five nitrogen (N) fertilizer treatments were applied to build up levels of nitrogen variation in potato fields in Israel in spring 2006 and 2007. Reflectance of leaves was measured in the field over a spectral range of 400–900 nm. The leaves were sampled and analyzed for petiole NO 3–N and leaf percentage N (leaf-% N). Prediction models of leaf nitrogen content were developed based on an optical index …
