Develop a solid fertilizer spreader for putting fertilizers under vegetable seedlings in new lands [electronic resource].

Includes reference.

The planting of vegetable under drip-irrigation needs prepared soil to be suit bed for vegetables seedlings. To carry out this work the manure spreader was developed to put mixture fertilizers in trenches and covered it. The studied parameters were; three forward speeds of 5.96, 7.95 and 10.04 km/h; three feeding gate height of 60, 80, and 100 mm and three conveyor rotating speeds of 14, 22 and 31 rpm. The obtained results showed that at forward speed of 5.96 kmlh, 100 mm feeding gate height and conveyors speed of 31 rpm gave the best needs of vegetables seedling where in this case showed the minimum operating cost was 2.73 L.E/m3 , volumetric of mixture fertilizers was 5.08 m3/fed, established thickness of fertilizer layer in trench was 3.63 mm and the lower power consumed was 14.74 kW. The research concluded that the developed machine can prepare the soil to suitable for vegetable seed or seedling plant. The developed fertilizing machine makes a trench, put the mixture fertilizers in the trench and cover the fertilizer by metal plate. Consequently, this machine can be Widely used to prepare the soil in new reclaimed and desert lands especially for the vegetable crops commonly sensitive for fertilizer reduced.
