The effect of preservative agriculture technology on some spectral and physical properties of the soil according to the years of application in the Telkif Region

Conservation agriculture is one of the innovative techniques that has proven to be successful in terms of decreasing effort, time, and expenses. The current study used two key criteria to prove some relevant findings for Conservation agriculture in order to test the results of its success, they are the bulk density (which measures soil compaction, de-oxidation and a lack of ventilation) as well as the percentage of soil organic matter. Four regions have been selected for different periods of adoption of conservation agriculture (2, 5, 10) years and other area is a unplowed fallow soil for comparison. The results revealed a great superiority for all conservative agriculture regions in terms of organic matter percentage and soil compaction. Also, the results also indicated that the spectral signatures of the areas that have been used for long-term the conservation agriculture are less than those of fallow soil due the effect of organic matter. This is an encouragement to use this technique of agriculture, where the soil surface appears to be unaffected by the agricultural machines.
