LPG has numerous applications in agriculture: thermal desiccation, grain drying, fuelling farm trucks, and pest and insect control. Remote rural areas cut off from infrastructure can use the advantages and power of natural gas that they would not invest into power cables.
Besides agricultural uses, LPG also has many other innovative uses.
Thanks to its clean-burning quality, LPG allows direct-fired heating systems to be used in grain dryers where 100% of the heat is directed to serve its goal. No combustion residues contaminate the grain, there is no risk of fires and residual water is removed. Direct fired burners are also used; these reduce overhead costs and extent lifespan. LPG also rules out any soot build-up.
By using the infrared radiation generated by gas, plant nurseries and horticultural centres also get the heat and CO2 they need so that the maximum intensity is at plant level. Infrared radiation also allows saving on heating costs, and insulation investments do not have to be as extensive. Different crops grown in the same space can, zone by zone, get the heat intensity they need and the entrepreneur can stick to a flexible production schedule. The LPG system takes up little space and the production facility operates much more efficiently.
On chicken farms, neither heating oil nor electricity can produce the same stress-free environment, where moderately moist air and an exact temperature control allows fast growth and an even feather layer. LPG also runs a lower risk for power outages and current fluctuations. There are no fuel residues or replacing heat lamps.
On pig farms, rapid-response infrared radiant heaters are appropriate for weaning rooms where piglets get the heat they need. LPG is in use as a background heat source in sow and fattening areas, as well as for mobile pig farming units.
Using flame to control weeds is one application for organic farming. A pure flame at a high temperature does what ordinarily a large quantity of pesticides might and the produce is unsullied by toxic chemicals. This technology is becoming more popular as the amount of poisons used in vegetable farming is regrettably high.
