Abstract: Provided herein are systems and methods for applying particle films to control stress on plant tissues. An exemplary method for controlling stress on plant tissues includes calculating a current plant tissue stress value for the plant tissues, and applying an effective amount of a particle film to the plant tissues if the calculated current plant tissue stress value is greater than or equal to a predetermined plant tissue stress value. The method may further include calculating a second current plant tissue stress value for the plant tissues after the application of the effective amount of the particle film, and calculating a future plant tissue stress value for the plant tissues. The calculated current plant tissue stress value, the second current plant tissue stress value, and the future plant tissue stress value may be analyzed to predict a future application of the effective amount of the particle film to the plant tissues.

Abstract: Provided herein are exemplary agricultural sunscreen formulations for use in the production of organic crops. One exemplary agricultural sunscreen formulation comprises on a weight to weight basis about 40% to 80% calcium carbonate, about 1% to 5% sodium bicarbonate, and about 15% to 59% water. Also provided herein are exemplary methods for making an exemplary agricultural sunscreen formulation for use in the production of organic crops. One exemplary method comprises combining a first amount of glycerin and an amount of water to form a first mixture, combining an amount of particles with the first mixture, combining an amount of a thickening agent and a second amount of glycerin to form a second mixture, and combining the first and second mixtures.

Abstract: Refrigerated containers that contain continuously circulating air or oxygen-containing gas into which ozone is injected to preserve perishable food products that are susceptible to spoilage when stored for extended periods of time are disclosed. The ozone content of the circulating air is continuously monitored by an ozone sensor and adjustments to the amount and rate of ozone injection are continuously made by a controller on the basis of signals from the ozone sensor and other sensors.
