Study the effect of the depth on soil reflectivity through the decomposition of orange leaves at Ramadi city – Sofia.

Abstract

One of the most crucial phenomena to examine is soil, as distant sensing is crucial to human sustenance and agriculture. The features of soil vary in response to particular stimuli, which alters their reflectivity and causes them to lose their distinctive qualities. This study will serve as the starting point for developing these diagrams since it focuses on determining the impact of soil depth on reflectivity, especially given the dearth of uniform soil reflectivity samples in the study region. A chosen orange leaf was collected, buried at two different depths (40 cm and 100 cm), and the reflectivity of the buried leaf and the soil around it were monitored during a six-month period.The results showed that the rate of reflectivity decreased by 13% during this wavelength (900nm), with an increase in organic matter on depth 40cm, and reflectivity decreased by 8% during this wavelength (900nm), with an increase in organic carbon in the depth 100cm. No discernible relationship between the rate of reflectivity decrease and changes in organic matter was seen during this time period. In order to avoid errors in future research, these findings should be applied to any subsequent research in the field, and the reflectivity difference should be determined
