Irrigation planning system

An irrigation planning system comprising:

• a processor;
• and
• a memory in communication with the processor, the memory containing program instructions that, when executed by the processor, are configured to cause the processor to perform a method, the method comprising:
• obtaining, by the irrigation planning system, irrigation data;
• obtaining, by the irrigation planning system, a first set of watering rates;
• generating, by the irrigation planning system, a first set of soil moisture estimates and a second set of soil moisture estimates,
• wherein the first set of soil moisture estimates and the second set of soil moisture estimates are based at least in part on the irrigation data, the second set of soil moisture estimates including a soil moisture estimate at a surplus zone depth layer;
• obtaining, by the irrigation planning system, a custom constraint;
• making a first determination, by the irrigation planning system, that the first set of soil moisture estimates satisfies the custom constraint;
• obtaining, by the irrigation planning system, a moisture reference value in response to making the first determination,
• wherein the moisture reference value is based at least in part on the second set of soil moisture estimates, the moisture reference value obtained by calculating a difference between a first soil moisture estimate at the surplus zone depth layer at a first time and a second soil moisture estimate at the surplus zone depth layer at a second time;
• making a second determination, by the irrigation planning system, that the moisture reference value exceeds a first threshold;
• and
• generating, by the irrigation planning system, an irrigation plan in response to making the second determination.

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• obtain, by an irrigation planning system, irrigation data;
• obtain, by the irrigation planning system, a first set of watering rates;
• generate, by the irrigation planning system, a first set of soil moisture estimates and a second set of soil moisture estimates,
• wherein the first set of soil moisture estimates and the second set of soil moisture estimates are based at least in part on the irrigation data, the second set of soil moisture estimates including a soil moisture estimate at a surplus zone depth layer;
• obtain, by the irrigation planning system, a custom constraint;
• make a first determination, by the irrigation planning system, that the first set of soil moisture estimates satisfies the custom constraint;
• obtain, by the irrigation planning system, a moisture reference value in response to making the first determination,
• wherein the moisture reference value is based at least in part on the second set of soil moisture estimates, the moisture reference value obtained by calculating a difference between a first soil moisture estimate at the surplus zone depth layer at a first time and a second soil moisture estimate at the surplus zone depth layer at a second time;
• make a second determination, by the irrigation planning system, that the moisture reference value exceeds a first threshold;
• and
• generate, by the irrigation planning system, an irrigation plan in response to making the second determination.
