the research aims to identify qualitative deterioration that has occurred on the competence of productivity for the different administrative districts to assist in the preparation of plans and programs for the improvement and maintenance of agricultural soil, which helps to guide the farmer to achieve the best cropping pattern. This study was reached to the number of districts increase from the 164 districts during the first period for the classification (1996/2000) to about 209 districts during the second period for the classification (2006/2010), while planted area of field crops Increased during the first period from about 7.8 million fed to 8.3 million fed during the second period. The qualitative deterioration converted to the deterioration during both study estimated at about 67,5 thousand fed. By studying the impact of qualitative deterioration on the net return of the main agricultural crops for some alternative course during the period (2010/2015) the highest value for the course (clover and rice) at about 941 thousand L.E , the highest value of the loss of jobs for a number of human labor about 6 million workers to course (winter onions and rice), By evaluating the impact of qualitative deterioration on food security for the most important agricultural crops, the results showed that the highest of amount loss in the local production, available for consumption, net food and the in the wheat crop the losses as a result of qualitative deterioration of about 594 thousand tons, 1.14 million tons, 776.3 thousand tons, while the self-sufficiency of wheat was about 51.8%. The study also showed that the volume of investments directed to overcome the qualitative deterioration of agricultural land increased from about 47.8 million L.E during the first year of the investment plan to about 452.3 million L.E during sixth year of the plan. The carried out of the investment plan reached in the first year of the planabout 31.2 million L.E, and about 413.9 million L.E during sixth year of the plan, the total area which was carried out improvement about 37 million fed. In the light of the obtained result, the study recommends the importance of put an integrated plan for expansion in different improvement programs for all governorates of the Republic and encourage and increase investments directed to projects for improve the land in the country.
