Abstract

An economic and practical system for enhancing plant growth by delivering gaseous carbon dioxide to the plants. The vegetation is planted within an elongated trench preferably in an overstocked condition whereby the vegetation is permitted to grow sufficiently to define a closed canopy. The carbon dioxide-rich gas may be delivered to the trench by conduits beneath the level of the canopy. The trenches can include a floor and side walls which extend vertically upwardly and divergently from each other to restrict the flow of air beneath the canopy thereby minimizing the dilutive effects of the atmosphere. The trenches can also be oriented generally perpendicularly to the prevailing wind direction to minimize the tendency of the wind to carry off the carbon dioxide.
