Abstract
Methods and systems for providing nutrients to a plant are provided herein in which a feed solution containing water and solubilized nutrients are delivered to the plant at a desired ratio of concentration of water to fertilizer at each watering event in order to provide the plant with a consistent water to mineral ratio within their vascular system.
Claims24
A method of providing nutrients to a plant, comprising:
- for each current feeding of a plurality of feedings, performing the following steps:
- initiating a current feeding after a non-feeding interval by applying a feed solution to the plant, wherein the feed solution comprises water and fertilizer at a target ratio of concentration of water to fertilizer to be maintained in a root zone of a plant over the plurality of feedings;
- determining a ratio of concentration of water to fertilizer in the root zone during the current feeding,
- adjusting the non-feeding interval prior to the next feeding based on the ratio of concentration of water to fertilizer;
- and
- stopping the current feeding when the determined ratio is at about the target ratio.

A computerized method of providing nutrients to a plant, comprising:
- using a controller to perform the following steps for each current feeding of a plurality of feedings:
- applying a control signal to initiate the current feeding after a non-feeding interval by applying a feed solution to the plant, wherein the feed solution comprises water and fertilizer at a target ratio of concentration of water to fertilizer to be maintained in a root zone of a plant over the plurality of feedings;
- receiving a sensor signal indicative of the ratio of concentration of water to fertilizer in the root zone during the current feeding,
- adjusting the non-feeding interval prior to the next feeding based on the ratio of concentration of water to fertilizer, and
- applying a control signal to stop the current feeding when the determined ratio is at about the target ratio.
2 more elements
A system for providing nutrients to a plant, comprising:
- a feed solution comprising water and fertilizer at a target ratio of concentration of water to fertilizer to be maintained in a root zone of a plant over the plurality of feedings separated by a non-feeding interval;
- a feed solution source;
- a feed solution delivery system for delivering the feed solution from the feed solution source to the root zone of the plant;
- a sensor configured to generate a sensor signal indicative of the ratio of concentration of water to fertilizer in the root zone during a current feeding;
- and
- a controller configured to perform the following steps for each feeding over a plurality of feedings:
- apply a control signal to the feed solution delivery system to initiate the current feeding after the non-feeding interval by applying the feed solution to the plant;
- receive the sensor signal indicative of the ratio of concentration of water to fertilizer in the root zone during the current feeding,
- adjust the non-feeding interval prior to the next feeding based on the ratio of concentration of water to fertilizer, and
- apply a control signal to the feed solution delivery system to stop the current feeding when the determined ratio is at about the target ratio.
