Calibration equation of neutron probe in the soil.

Serial number	Instrument model of neutron probe	Depth of measurement (cm)	Calibration equation
1	L-520D	10	θ = 7.12 + 49.61 × (R/Rω)
2		30	θ = 5.071 + 58.224 × (R/Rω)
3		≥40	θ = −0.83 + 58.102 × (R/Rω)

Θ, volumetric soil water content (%); R, average of neutron readings at different depths of soil (counts/s); Rω, calibration number of neutron probe (counts/s).
