Remote sensing has provided valuable insights into agronomic management over the past 40 yr. The contributions of individuals to remote methods have lead understanding how leaf reflectance and emittance changes in response thickness, species, canopy shape, age, nutrient status, water status. Leaf chlorophyll preferential absorption at different wavelengths provides basis for utilizing with either broad‐band radiometers typical current satellite platforms or hyperspectral sensors that measure narrow wavebands. Understanding various vegetative indices crop canopies quantify parameters, e.g., area, cover, biomass, type, yield. Emittance from is a temperature infrared thermometers fostered stress currently used requirements. These tools are being developed as we learn use information measurements range sensors. continues evolve tool scientists, consultants, producers about status their crops. This area still relatively new compared other fields; however, content providing improved decisions. article details our been quantitatively assess parameters some challenges facing future generations scientists seeking further advance applications.
