(1) The condensation and ammonification tests is proceed by using pyrrolidone as the start material.

(2) Effect of genera carboxylic acid on urease, ammonification, nitrification of brown soil was studied through an indoor incubated test.

(3) Ammonification, nitrification and nitrogen assimilation in HA - TF are predominant.

(4) Results: 1. The AGM properties: (1) AGM could be aggregating into various particles responsible to the degree of ammonification.

(5) Application of IFC at a proper rate can slightly accelerate ammonification and inhibit denitrification in the soil, and yet does not affect much microbial biomass in the soil.

(6) A mass of ammonifiers in water body and sediment can make ammonia accumulate in water body through ammonification .

(7) The influence of the compound fertilizer which is made of the ammonification of ammonia sulfite pulp black liquid on the soil urease activity.

(8) For example, enzymes have a catalytic formation of urea, the ammonification were discharged through the urine, another enzyme carbon dioxide emitted by the lungs .

(9) Two bacterial strains A1 and A2 screened from the biofilm of BAF reactor were found capable of ammonification.

(10) In this paper, the polyacrylate nanoparticle emulsions was synthesized by the methods of seed microemulsion polymerization and final ammonification .

(11) The sulfur nutrient was significantly affected by fertilization system. The nitrogen fertilization could improve the quantities of ammonification bacteria in soil.

(12) The respiratory intensity of the contaminated soil decreased by 29.93% while ammonification and nitrification increased significantly over that of control soil.

(13) The AGM properties: (1) AGM could be aggregating into various particles responsible to the degree of ammonification.
