This study aimed to build and develop an innovation model appropriate for disseminating knowledge of correcting salty soil conditions in northeast Thailand. The sample consisted of 20 purposively selected experts in disseminating educational innovation and technology and experts in agricultural promotion in correcting salty soil. They were considered according to the established requirements. The dissemination model was developed using delphi technique. The collected data were analyzed using basic statistics, median, and interquatile range. The findings revealed that the model of disseminating knowledge of correcting salty soil conditions in northeast Thailand was appropriate and feasible according to the established requirements (Mdn>3.50 and IQR<1.50) comprising 4 stages: preparation for dissemination stage, operation of dissemination stage, conclusion and dissemination stage, and report on dissemination results stage.
