Replacement Investment with Pallet Fuel System in Greenhouse Fruit and Vegetables

This study aim ed to analyze the replacem ent investm ent of the diesel fuel system w ith the pallet fuel system in the Korean farm ing sector. Equivalent annual annuity approach w as used to resolve a discrepancy of useful life in capital goods and to facilitate investm ent analyses in an independent perspective. D ata w as obtained from previous studies on econom ic analysis of greenhouse tom ato, paprika and cucum ber. Results show ed that the replacem ent w ith the pallet fuel system w as acceptable irrespective of the rem aining period of useful life for the diesel fuel system . In addition, sensitivity analysis w ith governm ent support level, repair cost, and light and heat energy cost show ed robustness in the possibility of replacem ent w ith the pallet fuel system w hile the speed of replacem ent w as accelerated w ith an increase in the am ount of diesel fuel used and price of diesel fuel, and a decrease in price of the pallet fuel. The result im plied that the replacem ent investm ent rather than a new investm ent w as appropriate for existing greenhouse farm ers and the pallet fuel system w as acceptable to replace existing diesel fuel system in producing greenhouse tom ato, paprika and cucum ber.
