An outlet is configured to allow the liquid to exit the container. A float is disposed within the container. A valve is actuated based on a position of the float within the container to open the valve at a first liquid level within the container and to close the valve at a different liquid level within the container.

An apparatus and system for growing plants in a controlled environment comprises an enclosure, at least one basket for receiving plant material to be grown in the apparatus, and at least one cassette for receiving a basket therein. The apparatus further comprises a drive mechanism, said drive mechanism operatively coupled to the at least one basket and/or the at least one cassette, that imparts a drive force to cause the at least one basket to rotate in the at least one cassette and in the enclosure. The apparatus and system also include a climate-control mechanism that may include a light source, a fan, a ventilation system, an air passage, and ductwork. The apparatus and system also include a trough with a sump for drainage of the trough, an intake aperture, a baffle, a closure, an air intake sleeve, and an intake fan.

Techniques for horticulture light are provided. A horticulture light can monitor at least one characteristic of a defined region in which at least one plant is planted in a horticulture environment in which horticulture light bulb is installed, determine at least one action for the horticulture light bulb to perform based on a state of the at least one characteristic and at least one objective of the installation of the horticulture light bulb in the horticulture environment, and execute the at least one action.

In an embodiment, an agricultural intelligence computing system stores a digital model of crop growth, the digital model of crop growth being configured to compute nutrient requirements in soil to produce particular yield values based, at least in part, on data unique to an agricultural field. The system receives agronomic field data for a particular agronomic field, the agronomic field data comprising one or more input parameters for each of a plurality of locations on the agronomic field, nutrient application values for each of the plurality of locations, and measured yield values for each of the plurality of locations. The system computes, for each location of the plurality of locations, a required nutrient value indicating a required amount of nutrient to produce the measured yield values. The system identifies a subset of the plurality of locations where the computed required nutrient value is greater than the nutrient application value. The system computes, for each of the subset of the plurality of locations, a residual value comprising a difference between the required nutrient value and the nutrient application value. The system generates a residual map comprising the residual values at the subset of the plurality of locations. Using the residual map and the one or more input parameters for each of the plurality of locations, the system generates and stores particular model correction data for the particular agronomic field.

Monitoring systems for center pivot irrigation systems and methods of irrigating an agricultural crop using the irrigation systems are provided. The irrigation systems may comprise a plurality of in-canopy sprinklers. The monitoring systems are configured to detect an operational condition of the plurality of in-canopy sprinklers, including whether individual sprinkler heads have become detached from the irrigation system main line, or whether an individual sprinkler head has become clogged, and alert an operator with a time and/or location of the occurrence of an event associated with one or more of the sprinklers.
