An example method of air circulation among crops may include obtaining an indication of mitigation work to be performed on a crop within an agricultural area using air movement. The method may also include obtaining a navigation path to follow within the agricultural area based on the mitigation work to be performed. The method may further include directing movement of an air blower system along the navigation path. The air blower system may be configured to circulate air among the crops along the navigation path. The method may also include obtaining data from one or more sensors associated with the air blower system while the air blower system is moved along the navigation path. The data may be related to the mitigation work to be performed. The method may further include directing adjustment of an operating condition of the air blower system based on the data.

A cloner may include a reservoir to hold a liquid, a lid with apertures to hold plant cuttings, stems, or roots, and a manifold mountable at or near a water line of the reservoir. One end of the lid may include a fan housing, and an opposite end may include ventilation holes. The reservoir may have a pump housing to hold a pump so that the pump does not become submerged in water, mitigating or preventing excess heat inside the cloner.

Disclosed is an agricultural air injection apparatus including: a compressor for compressing air; an air tank which has a pressure gauge and a safety valve for presenting overpressure and stores compressed air of high pressure in a set pressure condition; a decompression valve for decompressing air pressure discharged from the air tank; a sprayer for spraying water in a particle state in order to make vapor contained in the supplied air; a distributor which uniformly distributes the decompressed air to a plurality of flow paths and has a control valve to open and close the flow paths; an air supply pipe which is buried in the soil where crops to be cultivated will be planted and has pores for supplying air passing through the distributor; and a controller which is connected to the compressor, the pressure gauge of the tank and the control valve of the distributor to control supply of the compressed air.

A method includes receiving a treatment temperature from a user device; positioning a tree within a treatment region of a canopy; flowing a fluid from a hot fluid generating system to the canopy; spraying the fluid from the hot fluid generating system into the treatment region of the canopy; and selectively enabling and disabling a fluid flow from the hot fluid generating system to the canopy to maintain the treatment temperature within the treatment region of the canopy.

A plant raising apparatus: a light source that emits light traveling toward an aboveground part of a plant; a heat insulating portion that has a light transmitting property and that partitions a space at a side of the light source and a space at a side of the aboveground part; and an air blowing mechanism that generates an airflow at a space between the light source and the heat insulating portion. Thereby, it is suppressed that the heat of high temperature air staying above the heat insulating portion having a light transmitting property adversely affects the plant.
