A nutrient control system for nourishing plants. An injector provides a quantity of nourishment having individual concentrations of specific nutrients. A conduit distributes the quantity of nourishment to the plants. First storage memory stores initial data relating to the plants being nourished. A computer selects the amounts of specific nutrients and selects the quantity of nourishment to be applied to the plants based on the initial data in the first storage memory and, responsive to the selection, controls the injector to adjust the individual concentrations of the specific nutrients and the quantity of nourishment to be supplied to the plants as a function of the selected amounts of the specific nutrients and the selected quantity of nourishment.

An apparatus for controlling, during a given period of time, component quantities of a system affected by one or more stochastic variables and by one or more measured variables to direct the system toward a desired status, said apparatus comprising: controller means for controlling the component quantities of the system; determining means for determining the stochastic variables and the measured variables preceding the given period of time; memory means for storing initial data corresponding to the stochastic variables and the measured variables determined by said determining means; and computer control means including: estimating means for estimating projected stochastic variables for the given period of time based on the initial data in the memory means; calculating means for calculating projected component quantities having the highest probability of producing the desired status of the system based on the initial data in the memory means and based on the projected stochastic variables; and means, resPonsive to the calculating means, for controlling the controller means to adjust, during the given Period of time, the component quantities as a function of the projected component quantities.
