This research aims to study the quantities and types of agricultural waste in Egypt, and their geographical distribution in the governorates. This research also focuses on how to develop the agricultural resources available in Egypt, with the aim of reducing the use of chemical fertilizers, especially since Egypt suffers from a shortage in the supply of chemical fertilizers. Hence, Recycling agricultural waste and reusing it as Compost fertilizer contributes to alleviating this problem.
The main findings of the current research are:
1-Egypt produces annually about 85,5 million tons from agricultural waste, these
animal waste is estimated at about 42.7 million tons, represent %50 from the total agricultural waste, on the other side the Agricultural crop waste which represent about40.6 million tons , represent 47%, Poultry waste also contributed about 2.1 million tons, accounting represent 3%.
2-The area of agricultural land in Egypt is 9.7 million feddan, and its total needs for Compost are estimated at about 59.7 million tons, with an average of 6.1 tons per feddan.
3-The total number of compost factories in Egypt reached about 85, producing 128 thousand tons of compost fertilizer, with an average of 1.5 thousand tons per factory
4-about 25.6 million tons are consumed in feeding farm animals, which constitutes 30% of the total agricultural waste in Egypt , about 10.2 million tons are recycled , Thus, the amount of agricultural waste that can be exploited in the production of compost fertilizer is estimated at about 59.2 million tons, or 57.5% of the total agricultural waste produced by Egypt.
5- Agricultural waste contains 2,7 million tons of the main fertilizer elements , including 1,4 million tons of nitrogen 365 thousand tons of phosphorus , and 982 thousand tons of potassium..
6-Organic fertilization saves 25% of the total irrigation water. This means that if we expand the use of compost fertilizer, more than 11,7 billion m3 of irrigation water can be saved, which can be used to irrigate more than3,3 million feddan of land agricultural.
7-In the event of expanding the use of compost fertilizer, the agricultural land needs for chemical fertilizers will decrease from 12.5 million tons to 5 million tons in Egypt, thus saving more than 7.5 million tons of chemical fertilizers currently used.
8- The total needs of organic agriculture in Egypt for compost fertilizer, amounting to an area of 623 thousand feddan in 2022, are estimated at about 3.8 million tons.
