In one aspect, a method for compressing crop material for ensilage may include monitoring, with a computing device, a location of a work vehicle within a silage heap as the work vehicle traverses a layer of crop material within the silage heap. The method may also include determining, with the computing device, a current density of the layer of crop material as the work vehicle traverses the layer of crop material. Furthermore, the method may include controlling, with the computing device, an operation of the work vehicle based on the monitored location and the determined current density such that the work vehicle compresses the layer of crop material.

An apparatus for controlling fermentation of natural material. The apparatus includes one or more sensors configured to measure at least one property of natural material, a container configured to contain a chemical reactive agent reducing or limiting a fermentation process of the natural material; a valve coupled with the container; and a controller configured to process the measured at least one property of the natural material, and, if the processing meets a predetermined condition, control the valve to open so that the chemical reactive agent is released into the natural material in order to limit the fermentation process of the natural material.

A CA system includes a gas supply device which performs a gas supply operation of supplying nitrogen-enriched air into a container, and a controller which performs the gas supply operation so that the inside air has a desired composition. The controller performs carbon dioxide priority control in which the controller performs the gas supply operation if an oxygen concentration of the inside air is equal to or higher than a ceiling concentration higher than a target oxygen concentration, stops the gas supply operation if a carbon dioxide concentration of the inside air is lowered to a critical concentration lower than a target carbon dioxide concentration, and restarts the gas supply operation if the carbon dioxide concentration of the inside air has reached a restart concentration higher than the target carbon dioxide concentration through breathing of the plants.

The present disclosure describes methods and apparatus for remote sensing with data analytics. The methods and apparatus have many applications including monitoring the quality of grain during storage and/or transport. The present disclosure describes a way to collect temperature and other environmental data to describe and predict quality of stored grains, current and future, based on a myriad factors including fumigation, external temperature and humidity, in storage grain temperature and humidity.

While an inside air control system is performing an air composition maintenance action, a controller instructs a gas supply device to operate while switching among a first supply operation, a second supply operation, an outside air supply operation, and a standby operation. In the first supply operation, first low oxygen concentration air is supplied into a container. In the second supply operation, second low oxygen concentration air having a lower oxygen concentration than the first low oxygen concentration air is supplied into the container. In the outside air supply operation, outside air is supplied into the container. In the standby operation, supply of the low oxygen concentration air and the outside air into the container is stopped.
