Using Space-borne Hyperspectral Imagery on Mapping Nitrogen Fertilizer Excess to the Environment
Yehia H. Miky, Ahmed F. El Shouny
Nowadays, Farmers tend to apply high rates of fertilizers such as Nitrogen (N) in order to get a high yield. But the challenge is how to optimize nitrogen (N) management to ensure high yield production while improving N use efficiency and protecting the environment. The calculation of N nutrition index (NNI) requires destructive sampling and chemical analysis to determine biomass and plant N concentration, which is time and cost consuming and, thus, impractical for in-season site-specific N management across large areas. The objective of this study was to evaluate the potential of using space-borne hyperspectral remote sensing imagery to track excessive fertilization areas to protect environment from Nitrogen excess. The study site is located at AtTawdihiyah farm, which was conducted on a 50 ha sandy loam soil in the Eastern Province of Saudi Arabia. To study the Effect of Nitrogen Fertilizer on the Environment of AtTawdihiyah region, four sets of Hyperspectral Imagery (EO-1 Path/Row 165/43) were chosen to represent the four seasons. Narrowband greenness VIs were computed. Biomass and Plant N concentration the results indicated that, all VIs used were significantly correlated with the N concentration among all seasons. However the proposed technique have been used to conduct precise Nitrogen content, it is also needs a ground based validation under different on-farm conditions using different types of satellite data
