TECHNIQUE AND DEVICE FOR AUTOMATED CONTROL OVER CROPS PRODUCTIONAL PROCESS WITH REGARD FOR SELF-ORGANISATION Russian patent published in 2009 - IPC A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the sphere of agriculture immediately dealing with crop husbandry technologies. Among the variables available one identifies the ordinal variable most prone to speedy variation and most seriously affecting the processes which is optical radiation total exergy in reference to plant photosynthesis. After that one specifies the control parameter(s) such as temperature, air humidity, soil humidity, concentration of root nutrition mineral elements. Measurement of the optical radiation total exergy in reference to plant photosynthesis is done. Relying on the test base of actual states one identifies the relatively minimum control parameter; based on the results one purposefully affects the plant to increase the parameter value but no more than by 5% of its actual current value. One evaluates the plant actual condition against the ordinal variable value with the current value of exergy capacity within the plant zone. In case there has been increase of the ordinal variable value detected one provides for the value of the same control parameter being increased but no more than by 5% of its initial value. Interference with the plant living activities continues until the ordinal variable value ceases fluctuating. If initial impact onto the control parameter has resulted in reduction of the ordinal variable value another interference is undertaken to decrease the control parameter value by no more than 5% of its initial value. After that one again identifies the relatively minimum control parameter relying on the test base of actual states and repeats the above sequence of operations related thereto. The maximum interval with any measurement of the ordinal variable and control parameters shall be 3 hours. The device is equipped with an optical radiation exergy sensor, a valuator calculating the exergy capacity rated value, a comparator, a control key, a timer, a memory unit, an ambient temperature sensor, a soil temperature sensor, a soil humidity sensor, a logical control switch and four control keys.

EFFECT: series of inventions enabling crops yield improvement.
