| Abstract | ||||
| The study aims at shedding lights on using chemical fertilizers as one of agricultural production needs which is necessary to achieve the agricultural development through analyzing the most important economical changes that are related to using fertilizers in Egyptian agriculture, and to show how different kinds of fertilizers substitute each other. And to determine and measure the factors that determines the demand on chemical fertilizers after the economic liberalization stage and after the agriculture development and credit bank stopped dealing in agricultural production needs. The study showed that Ammonia nitrate fertilizer production 33.5% and the urea production 46% annually increased by 234 and 37.2 thousand tons respectively. While the consumption annually decreased by 19.6 and 42.2 thousand tons. This reflected on the produced quantity of nitrogenous fertilizer that the increase in produced quantity was estimated by 319.5 thousand tons, and the decrease in the consumed quantity was estimated by 84.2 thousand tons. So the average of the annual decrease of the amount of the nitrogenous fertilizer needed per feddan was estimated by 8.1 kg. The produced quantity of phosphatic fertilizer annually decreases by 13.9 thousand tons, while the consumption of potassic fertilizer increases by 3.8 thousand tons. The functions indicated that the urea fertilizer 46% can not be substituted with any other kind of fertilizers, and this shows that the other kinds of fertilizers can not be used in any concentration instead of the urea fertilizer .The study assures on producing the high concentrated fertilizers more than the low concentrated Iertilizers. The results of demand functions on nitrogenous fertilizer showed that the most important factor that affects on the consumed quantity is the real price. and its impact is an appositive impact. While the real income and the production per leddan of wheat have a direct impact. There is no effect appeared after the credit bank left fertilizers market. The demand function on phosphatic fertilizers indicated the integrated relation between nitrogenous fertilizer and tl',', phosphatic fertilizers, that the sign of nitrogenous fertilizer price and the phosphalic fertilizers price was negative, while the direct positive relation of wheat production was indicated, and no effect appeared after the bank stopped dealing in fertilizers .The demand function on potassic fertilizers indicated the importance of nitrogenous fertilizer price and the phosphatic fertilizers for the needed quantity , and there is an appositive relation between them . There is no effect appeared after the agriculture development and credit bank stopped dealing in chemical fertilizers market. | ||||
