Drip irrigation125 year ago
How it Works
½” dripline grid is buried 15 to 60 cm. deep where it slowly and evenly places effluent into the soil.

Methane – CH4 -- > CO2 H2O O2 H2Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period
