It considers chemical fertilizers of important strategic industries close due to its relation to food production, in addition to being one of the main factors of production in the Egyptian agriculture, as they are influential and effective role in agricultural development to make it one of the key factors to increase agricultural production in the vertical direction to the face of limited planting areas, and is a problem Find the increase in production costs as a result of excessive use of fertilizers in agriculture in Egypt, in addition to higher prices recently due to higher energy prices, hence the importance of research in order to minimize the use of these fertilizers, which help to solve the former problem is displayed in addition to achieve dimensional Nile implications to increase wasteful in their use. 
Research aimed to identify the parameters and indicators of crop structure and the actual most important resources used to produce it on top of chemical fertilizers with both old and new lands, in addition to proposing the installation of Mahsouli more satisfactory to minimize needs fertilizer to try to reduce the quantities consumed of these fertilizers in the Egyptian agriculture, rely Find in achieving its objectives on Use descriptive economic method by identifying the milestones and indicators of crop structure-based, in addition to the quantitative economic method of using linear programming method to minimize the needs fertilizer for installation crop quo and using the QSB program, using Palmtoffer and the availability of published and unpublished data and issued by the scientific community. 
The results showed that the crop structure more appropriate according to the minimization needs fertilizer in the old territory achieves savings in chemical fertilizers reached about 20.14 thousand tons Accordingly, this model achieves the objective, which is to minimize the needs fertilizer so as to achieve total net higher than the actual counterpart dividend by 845, 2 million pounds as also achieved a saving valuable employment amounted to about 33.12 million workers represent about 5.1% of the total used in the installation actual crop, as well as the crop structure more appropriate to achieve the minimization of water needs where he achieved a saving estimated at 150.6 million m3 account for about 0.56% of the total water needs of the crop actual installation. 
The results showed that the crop structure more appropriate according to the minimization needs fertilizing in the new territories to achieve savings in chemical fertilizers reached about 5 tons Accordingly, this model achieves the objective, which is to minimize the needs fertilizer, also achieves total net higher than the actual counterpart yield increased by 329 million pounds also, also achieved savings in employment of about 12 million workers represent about 8.2% of the total used in the actual installation crop, also achieved savings in water needs amounted to approximately 26.6 million m 3 represents about 1.15% of the total water needs of the crop composition actual. 
The results showed that the crop structure more appropriate in the old and new territories has achieved savings of resources used to produce the result that in addition to the agricultural sector indirectly is to increase the floor area where the increase in net revenue resulted in the addition patch ground is estimated at about 207 thousand acres, savings also led in employment to add a patch ground is estimated at about 502 thousand acres, while Ade Aalover in the total water resources of chemical fertilizers to add a patch ground is estimated at about 193.78 thousand acres for each of them, respectively, and this means that the crop structure more appropriate to add 980 thousand acre if they are directed to the cultivation of strategic crops with low self-sufficiency will lead to reduce the amount of imports from the country, which is reflected on the deficit reduction in the Egyptian trade balance.
