CENTER-PIVOT IRRIGATION WATER MANAGEMENT BASED ON SOIL SPECTRAL REFLECTANCE TECHNIQUE
Center pivot irrigation system has the potentiality for economically net return of various crop patterns, although it’s higher fixed cost’s inputs. Therefore, water management under the specified center pivot irrigation system can play a crucial role in maximizing water unit productivity and enhancing physical agricultural resources sustainability. Hereby, the aim of this research was to evaluate the optional of a general reflectance model based solely on soil moisture distribution pattern as a key for a farm irrigation management under center pivot irrigation system. Data revealed that the relative reflectance was strongly correlated with soil moisture contents. However, the best correlation was found act high soil moisture level between the reflectance values of 700 nm (Red-NIR) wave length and the volumetric water content (R²=0.9) at the short time (one hour). Moreover, the results of this study help to appear the strong in influence of soil moisture on spectral reflectance and absorption features and should aid in the development operational and management algorithms of on-farm irrigation systems.
