Amina, Bagi Tani, Orgami and Sari Tanah are byproducts of industry of monosodium glutamate. They could be a source of pollution to the environment. To solve the problem, they have been processed to liquid organic nitrogen fertilizer. The research of application of these byproducts has been reported on their effect to nutrient quality and to change of status of Sulphur, Chlor, and sodium in the soil. In this study there are five kinds of N fertilizers those are ZA, Amina, Bagi Tani, Orgami, and Sari Tanah each applied in three doses of 125 kgs, 157,5 kgs, and 190 kgs nitrogen per hectare. The design of this experiment was randomized block with three replicates. The result shows that there was no interaction between fertilizers. Nutrient quality status and sugar yield at the optimal balanced leaf nutrient by using ZA at 125 to 190 kgs N per hectare reached + 1 to + 3 above the optimal level. While at the same dose, Amina, Bagi Tani, Orgami, and Sari Tanah reached only - 2 to - 1 below the optimal level. Amina and Bagi Tani could increase the content of sulphate and sodium in the soil Orgami and Sari Tanah could increase the content of chlor and sodium, while ZA could increase the content of sulphate in the soil. The residual sulphate in the soil was very high after harvest, and before and after application of ZA, Amina, Bagi Tani. The residual chlor in the soil was low to normal after harvest and before and after the application of Orgami and Sari Tanah. The
residual sodium in the soil was normal after harvest, before and after application of Amina, Bagi Tani, Orgami, and Sari Tanah
