Development and testing of tractor-mounted fertiliszrs spreader [electronic resource]

Includes bibliographic reference

The lack of efficiency and effectiveness in fertilizer applications in many crops has been continues challenge to sustainable use of inorganic/commercial fertilizers, the right balance in fertilizer application is an important element in nutrition management in Egypt, and promoting efficient and effective use of fertilizer has emerged as an important target of policies and programs in recent decades. However, fertilizers distribution in Egypt is still mostly done manually due to small field sizes, and it is laborious, costly, and the spread pattern is not accurate. So manufacturing such small fertilizer distributor that can be mounted on a tractor or any smaller carriage could provide a simple mechanized solution for fertilizing small fields in Egypt. So, this study is carried out to manufacture and test a tractor-mounted spreader and this could help farmers to increase efficiency and effectiveness in fertilizer use in small scale applications. Fertilizers spreader consisted of; frame, spreading material hopper, agitator, spreading disc with four adjustable blades (fins), and electrical control unit. In stationery mode experiments, Differences of distribution density in both sides of the spreader have been measured under different possible combinations of settings till best results obtained. Many tables have generated to get the recommended setting to deliver specific amount with best uniformity
