العلاقة بين الانعكاسية الطيفية والمحتوى العضوي لتربة مناطق النجف الأشرف عند الطول الموجي (0.4 -1.6مايكرومتر)

Abstract

The property containing the soil organic matter properties of the task that affect the impact of a major on the characteristics of the reflective spectrum of the soil, and organic content in soil is one of the important characteristics of the farms due to adjust their physical and chemical as well as fertility. So was reached in this study that there is an inverse relationship between reflectivity and spectral content of the organic soil areas of Najaf at a wavelength (0.4-0.6) micrometers, as well as distinguish soils with higher organic content than others because it is an increase of organic soils under the mirror making it easy to distinguish them visually from the image space.
