Abstract: System for monitoring and regulating plant productivity comprising: a memory for storing instructions; a processor for executing the instructions to cause a method of monitoring and regulating plant productivity to be performed, the method comprising: receiving field data from monitoring sensors; computing, by the at least one processor executing a machine learning algorithm, a predicted value for a variable associated with the production environment condition of a crop field, the machine learning algorithm having been trained based on a training set comprising one or both of (a) the field data from the monitoring sensors, and (b) a generated feature derived from the field data; and determining, based on a threshold associated with the variable, that the predicted value for the variable indicates that an intervention in the crop field is to be initiated; and in response to the determining, causing a controllable device to vary the production environment condition.

Abstract: There is disclosed a method and system for regulating plant irrigation at a crop field. The method comprises obtaining soil water tension (SWT) data and/or soil water content (SWC) data corresponding to a crop field. The SWT data and/or the SWC data is segmented into three segments. A respective line of best fit is determined for each of the three segments. The intercepts of the lines of best fit are used to determine an irrigation start threshold and an irrigation stop threshold. Devices that control irrigation for the crop field are caused to start or stop irrigation based on the irrigation start threshold and irrigation stop threshold.

Abstract: The present technology generally relates to a porous medium parameter measurement device. The porous medium parameter measurement device comprises: a liquid permeable portion comprising a fluid permeable component and a polymer swellable solution; and comprises a gas permeable portion comprising a gas permeable component. The liquid permeable portion is in operative communication with the gas permeable portion through the gas permeable component; and the gas permeable component acts to purge gases from the liquid permeable component and the polymer swellable solution.

Abstract: The present technology generally relates to a porous medium parameter measurement device comprising one or more component selected from: a porous conductive component; a porous non-conductive component; and a selective component. The one or more component is in operative communication with each one of the one or more component and with a porous medium through a plurality of pores allowing a porous medium solution to reach diffusion equilibrium between the porous medium and each of the one or more component. The one or more component allows direct measurement of a multiplicity of parameters of the porous medium solution.

Abstract: A device for measuring an ionic concentration of an ionic compound in a porous medium solution contained in a porous medium. The device includes a sensing portion, a light source, and a light sensor. The sensing portion is miniaturized and includes a permeable material body defining a measuring cavity therein and is insertable in the porous medium to allow the porous medium solution to diffuse through the permeable material body. The light source illuminates the porous medium solution contained inside the measuring cavity. The light sensor detects a resulting light emanating from the porous medium solution, the resulting light having at least one spectral characteristic indicative of the ionic concentration of the ionic compound in the porous medium solution. There is also provided a method for measuring in situ an ionic concentration of an ionic compound in a porous medium solution contained in a porous medium.
