A calibration curve for measurement of soil moisture regimes by the neutron method is shown for a greenhouse study. A linear regression analysis was used to determine the equation for the best fitting neutron‐soil moisture data. The equation was established by relating percent of neutron standard and tension in atmospheres. This relationship was determined as log T = c + bY where T is tension in atmospheres and Y is percent of neutron standard.
