Relative gaseous losses compared to control from arable land after co-application of zeolite and biochar along with chemical fertilizers.

Treatments	NH3		CO2		CH4
	Year 1	Year 2	Year 1	Year 2	Year 1	Year 2
C	100	100	100	100	100	100
Z	45	34	105	71	58	47
B1Z	25	19	158	126	55	37
B2Z	12	09	221	200	53	38
B3Z	09	07	265	254	44	27

C = control, Z = zeolite @ 5 t ha^–1, B1Z = biochar @ 3 t ha^–1 + zeolite @ 5 t ha^–1, B2Z = biochar @ 6 t ha^–1 + zeolite @ 5 t ha^–1, B3Z = biochar @ 9 t ha^–1 + zeolite @ 5 t ha^–1.
