ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to a system and method for remote phytomonitoring and, more particularly, to a system and method which enable a grower to monitor and optionally control plant growth from a remote location.
Cultivation of commercial crops depends on the monitoring of various parameters of a plant or field. For example, maintaining the correct hydration, which is dependent on several factors including irrigation, scheduling and the like is crucial for the proper development of plants and as such, precise monitoring of the hydration, at any given stage of development is advantageous.
In the past growers have mainly relied on their intuition and expertise in assessing crop conditions. This expertise relied mainly on crop and soil inspection and observing the environmental conditions in which the crop was cultivated.
In recent years, growers have increasingly utilized systems and devices which include arrays of precise sensors for measuring the temperature and humidity and other related parameters of the environment and/or soil proximal to the cultivated plants.
The advent of such precise monitoring technologies and methodologies enabled growers to track and record changes in a field or greenhouse enabling close monitoring, in some cases, of a single plant.
For example, recorded sensor data can be analyzed and the resultant data incorporated into a plant hydration profile, such a profile can then be used to assess crop condition and development through daily and seasonal changes. For further details see, for example, Wolf, B. Diagnostic Technique for Improving Crop Production, Haworth Press, P. 185-187.
Although such methodology has substantially enhanced phytomonitoring, it is still difficult to use since it requires periodical on-site collection of the data recorded by the sensors, a task which can be difficult to achieve in cases of large and remote crops.
In addition, the data provided to a grower utilizing present day systems and methods is presented as numerical data. Such presentation can often be difficult to perceive and analyze and as such requires an experienced operator to decipher.
There is thus a widely recognized need for, and it would be highly advantageous to have, a remote phytomonitoring system and method devoid of the above limitation.
