Abstract: Plants use nitrogen as one of the essential elements required in their metabolism. Although the atmosphere is composed predominantly of molecular nitrogen, plants cannot break these nitrogen molecules into the elemental nitrogen required by the plants. In nature, bacteria "fix" the nitrogen in the atmosphere by using it to produce ammonia, which can be metabolized by plants. Nitrogen can also be introduced to the plants artificially, using natural or artificial fertilizer or even by direct injection of nitrogen into the soil. In all these cases, nitrogen is delivered to the plant via its roots. The present invention delivers instead ammonia to the leaves of the plants through foliar spraying by infusing water used in foliar spraying with ammonia. This is more efficient than delivery through roots of the plant, and greatly reduces the problem of fertilizer run-off.

Abstract: A device is provided for improving the results of foliar spraying of plants by gardeners. The device is attached to the end of a garden hose, and has a cannister containing CO 2 gas, an outlet, an actuator, and a mixing chamber. When the actuator is actuated, water enters the mixing chamber from the hose. The water is infused within the mixing chamber with CO 2 gas from the cannister, and the CO 2 -infused water leaves the device through the outlet. In this way, garden plants can be sprayed with CO 2 -infused water, which is beneficial compared to foliar spraying with ordinary water. The device may also be used in any small-scale plant growing application, such as by do-it-yourself cannabis growers.

Abstract: Fruit ripens as a result of the production of ethylene. It is often desirable to slow the ripening process in order to extend the shelf life of fruit to be sold. One method of slowing the production of ethylene is to increase the concentration of CO2 in the ambient atmosphere. However, this can endanger humans working with the fruit. Instead, a method of supplying CO2to harvested fruit in a way which does not increase the concentration of atmospheric CO2 is provided. Water is infused with CO2 and then sprayed onto the fruit. The invention can more generally be applied to other grocery produce so as to reduce spoilage of the produce.

Abstract: Foliar spraying of plants, such as in agriculture, over large areas cannot be practically done by hand. Instead equipment that carries out the foliar spraying is used. This equipment can be expensive to operate and adjust, the latter of which might be necessary as the plants grow or as the species of plant changes due to crop rotation. The use of drones to carry out the foliar spraying reduces cost and provides greater flexibility. Gas, such as CO2 or ammonia, is infused into water and the gas-infused water is loaded into a tank carried by the drone. The drone flies to a pre-programmed area of plants and foliar sprays the plants, then returns to be refilled with more gas-infused water.

Abstract: As part of the natural biological process, plants produce various metabolites. The amount of certain metabolites produced is important, especially during the growth phase of plants to be harvested in whole or in part. The production of metabolites is affected by the chemical environment within the plant, including the amount of CO 2 and O 2 . The production of metabolites of interest can be controlled by measuring the amount of the metabolites being produced by the plant, and then adjusting the amount of CO 2 and O 2 available to the plant. These are adjusted by adjusting the amount of CO 2 in water delivered to the leaves of the plant through foliar spraying and the amount of O 2 in water delivered to the roots of the plant.
