Abstract
The compost extract is primarily a liquid fertilizer, brewed by immersing organic compost in water in specified proportions and allowing the nutrients to leak as aerobic fermentation process. It is used as foliar fertilizer and soil amendment to supply the plant with water-soluble nutrients as well as to improve soil structure and water holding capacity. The aim of the research was to construct and evaluate the performance of a compost extract system to reach the optimum production parameters. Farm animal wastes were used as compost source. The performance of the manufactured system was studied under the different magnetic pumping period of (6,12,24 h/day);three dilution ratios of (1:10,1:15,1:20) ,different aeration period of (6,12,24 h/day).It has also been evaluated taking into consideration the following indicators: system productivity and specific energy requirements as well as physicochemical properties of compost extract. The experimental results showed that the highest value of unit productivity was 13.45 kg.day-1 with 1.29 kWh.Kg-1 specific energy. Based on the results, it can be concluded that the best dilution ratio is 1:20 and the preferable operating parameters for the compost extract production is 12 hours of aeration or magnetic pumping time. Furthermore, using a magnetic unit during pumping lead to improve the values of nutrients concentration N, P, and K. They were 1100, 97.86 and 5544 ppm, respectively compared with no magnetic treatment.
