The drip irrigation system allows for the irrigation of soil with carbon dioxide-infused water. The drip irrigation system includes a pipe having first and second inlets. The first inlet is adapted for receiving pressurized carbon dioxide gas, and the second inlet is adapted for receiving water under pressure. A plurality of drip nozzles are mounted to the pipe, such that each drip nozzle is in fluid communication with an interior of the pipe. An inner tube is mounted in the interior of the pipe and is in fluid communication with the first inlet for receiving the pressurized carbon dioxide gas. The pressurized carbon dioxide is expelled through a plurality of ports of the inner tube to mix with the water flowing within the interior of the pipe. This mixture forms water infused with carbon dioxide, which is then released, in the forms of drops, by the plurality of drip nozzles.
