Change of bacteria density in mixing ratio of artificial soil with soil on field application

Media1)	Bacteria (× 106, CFU/g)
	Field application
	Before	After
	Soil	35±5.3e2)	30±7.1e
	25% mixed soil	157±10.4d	253±29.1d
50% mixed soil	334±15.1c	437±10.2c
75% mixed soil	440±20.3b	532±32.1b
Artificial soil	624±41.2a	854±21.2a

Soil: 100% soil, control; 25% mixed soil: 75% soil and 25% artificial soil, (w/w); 50% mixed soil: 50% soil and 50% artificial soil, (w/w); 75% mixed soil: 25% soil and 75% artificial soil, (w/w); Artificial soil: 100% artificial soil
