Abstract

Described are apparatus and methods that automatically generate recommendations to growers. Using various different sets of data relative to a predetermined tract of agricultural land, typically including both imagery as well as electrical usage, they are processed together to make informed decisions regarding the state of the land, particularly with respect to water usage.

Claims

1. A method of irrigating a determined area of land that is serviced by providing water thereto using an irrigation system that includes an electrical pump, the method comprising the steps of:

inputting, into a memory of a computer system that includes a processor, at least one photograph of the determined area of land;

inputting, into the memory of a computer system that includes the processor, local energy data corresponding to energy usage of the electrical pump;

determining, based upon software automatically executed by the processor, in combination with the photograph and the local energy data, a distribution uniformity for the determined area of land, the step of determining including automatically adjusting value of the distribution uniformity factoring in soil uniformity within the determined area of land; and

irrigating the determined area of land using the electrical pump in accordance with the determined distribution uniformity and data from the electrical pump.

2. The method according to claim 1 further including the steps of:

comparing value of the determined distribution uniformity against a threshold distribution uniformity; and

transmitting an alert if the determined distribution uniformity is lower than the threshold distribution uniformity.

3. The method according to claim 2 further including the steps of:

further providing, based upon software automatically executed by the processor, in combination with the photograph and the local energy data, any additional geo-referenced location within the determined area of land for which there exists at least one cause of degradation of distribution uniformity due to (a) a clog or leakage in any component of the irrigation system;

(b) a soil erosion issue;

(c) an infestation of insects and/or fungus;

(d) non-optimal sensor placements; and

(e) malfunction of any component of the irrigation system.

4. A method of providing a farming prescription for a determined area of land that is serviced by providing water thereto using an irrigation system that includes an electrical pump, the method comprising the steps of:

inputting, into a memory of a computer system that includes a processor, at least one photograph of the determined area of land;

inputting, into the memory of a computer system that includes the processor, local energy data corresponding to energy usage of the electrical pump;

prescribing, based upon software automatically executed by the processor, in combination with the photograph and the local energy data, any additional information about the determined area of land, wherein the irrigation system is equipped to apply chemicals to the determined area of land, and, sensors are placed in the determined area of land; and

using the additional information to perform at least one of (a) updating amount of nutrients including amount of any N, P and K, where N is Nitrogen, P is Phosphorus and K is Potassium, to a geo-referenced location within the determined area of land, (b) updating sensor placements within the determined area of land, and (c) applying pesticide to counter infestation of insects and/or fungus within the determined area of land.
