## Abstract

A system for automating the growing of crops, such as grapevines. Combinations of data from sensors local to a vineyard, and from optional remote stations and sensors, is combined with a control system to accurately control the dispensing of water and chemicals such as insecticides, disease prevention fungicides and fertilizers. The materials are dispensed through a multiple channel conduit which allows conflicting, or incompatible, types of materials to be transported through a common assembly. Sensors are attached to the conduit so that the placement of sensors can occur simultaneously with the laying of the conduit. This approach also ensures correct placement and spacing of the sensors with respect to each plant, or plant area, to be monitored and treated.

## Claims

### Claim 1

A system for application of a material to a plurality of plants, the system comprising:
a plurality of sensors, wherein one or more of the sensors includes a leaf wetness detector for at least one of the plants;
a sensing unit for receiving one or more signals from the sensors;
emitters for emitting the material to a plant, wherein each emitter is associated with, and in fixed proximity to, one of the plants;
a control system for controlling emission of the material to a particular plant via the particular plant's associated emitter in response to a signal from the particular plant's associated sensor; and
relay means for relaying at least one signal derived from the one or more signals, wherein the relaying is from the sensing unit to the control system.

### Claim 2 (depends on 1)

The system of claim 1, wherein the sensing unit comprises:
a transducer for converting an analog signal to a digital signal.

### Claim 3 (depends on 1)

The system of claim 1, wherein the sensing unit multiplexes at least two of the one or more signals from the sensors.

### Claim 4 (depends on 1)

The system of claim 1, wherein the sensing unit buffers the one or more signals from the sensors.

### Claim 5 (depends on 1)

The system of claim 1, wherein the sensing unit pre-processes data derived from the one or more signals from the sensors and sends at least a portion of the derived data to the control system.
