Abstract: | pp. 859–864 Behavior of nitrogen in the media was investigated when the aqueous phase produced by methane fermentation was supplied as liquid fertilizer. When the aqueous phase was supplied to masa-soil, included in masa-soil was nitrified to . Additionally, in masa-soil, absorption was observed. On the other hand, in the case of coconut fiber and rockwool, has been hardly nitrified. From above results, it was determined that toxic effect from the aqueous phase on tomato plants growth was inhibited by means of the progress of nitrification and absorption by masa-soil. However, nitrification was restrained so that was fixed in masa-soil. On the other hand, in the sampled field soil, was not fixed, and was nitrified immediately. In the field soil, there was a great deal of generated . In comparison with masa-soil. |
