Removal of ammonia from poultry manure by aluminosilicates

•Using aluminosilicates as sorbents of ammonia from poultry manure is proposed.•The mean reduction level ranged from 26.41% to 29.04%.•The aluminosilicates can be used to neutralize ammonia released on poultry farms.

The aim of the study was to test the possibility of using aluminosilicates as natural sorbents of ammonia from poultry manure. The ammonia-absorbing properties of sodium bentonite and zeolite were confirmed in ex situ conditions. The most significant reduction in the level of ammonia with respect to the control was noted for 2% bentonite and 1% zeolite. The mean reduction for the entire period of the experiment ranged from 26.41% to 29.04%. The aluminosilicates tested can be used to neutralize ammonia released on poultry farms.
