Behavior of nitrogen in the media supplied with the aqueous phase produced by methane fermentation as liquid fertilizer
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,  /></span> included in masa-soil was nitrified to <span class= /></span>. Additionally, in masa-soil, <span class= /></span> absorption was observed. On the other hand, in the case of coconut fiber and rockwool, <span class= /></span> has been hardly nitrified. From above results, it was determined that <span class= /></span> toxic effect from the aqueous phase on tomato plants growth was inhibited by means of the progress of nitrification and <span class= /></span> absorption by masa-soil.</p> However, nitrification was restrained so that <span class= /></span> was fixed in masa-soil. On the other hand, in the sampled field soil, <span class= /></span> was not fixed, and was nitrified immediately. In the field soil, there was a great deal of generated <span class= /></span>. In comparison with masa-soil.</td> </tr> <tr> <td align=
