| Outline of Final Research Achievements |
The effect on utilization of bio-oxidized anaerobic digestate as nutrient solution for hydroponics on the use efficiency of nitrogen absorption in higher plants was evaluated.
Up to 85% ammonium ion in digestate was transferred to nitrate ion by bio-oxidization process. Tomato, lettuce and cucumber plants were grown hydroponically in an environment-controlled chamber with oxidized digestate, in which the ratio of ammonium to nitrate is controlled to as same as the ratio in commercial nutrient solution. Experimental results revealed that the growth and nitrogen absorption were modified by oxidizing digestate in all kinds of plants. On the other hands, largest growth and highest absorption were observed in that with commercial solution. This may be caused by excess and/or deficient nutrients in oxidized digestate.
