Improving Nitrogen and Phosphorus Efficiency for Optimal Plant Growth and Yield

Abstract: Nitrogen (N) and phosphorus (P) are the most important nutrients for crop production. The N contributes to the structural component, generic, and metabolic compounds in a plant cell. N is mainly an essential part of chlorophyll, the compound in the plants that is responsible for photosynthesis process. The plant can get its available nitrogen from the soil by mineralizing organic materials, fixed-N by bacteria, and nitrogen can be released from plant as residue decay. Soil minerals do not release an enough amo… Show more

“…Among the soil organic matters (SOMs), nitrogen (N), phosphorus (P), and potassium (K) are the most important nutrients for crop production. [94,95] In agriculture engineering, N, P, and K fertilizers are applied to improve the production of crops. However, excessive anthropogenic nutrient inputs have significant side effects economically and environmentally.…”

“…To adapt nutrient-deprived environments of plants, efficient and accurate detection of nutrient compounds in soil is essential for developing precision agriculture and the sustainability of the environment. [94,[97][98][99][100][101] The NIR reflectance-based sensors have been utilized to measure the spatial variation of both surface and subsurface soil nitrogen. [102][103][104] Optimal wavelengths for predicting the SOM content can be identified by studying the spectral reflectance of soil samples in the IR and visible wavelength regions.…”
