Irrigation Scheduler 4.1

Irrigation Scheduler overview

Welcome to the Irrigation Scheduler. This program has been brought to you by the support of the GREEEN grant and Michigan State University Extension. This program's purpose is to assist Michigan's farmers in managing their water resources efficiently. By accurately recording the amount of rain and irrigation that your field receives you can decide when to apply irrigation. Planning will help with efficient use of resources, benefitting everyone.

Data Inputs

  • Water Inputs:

    To use the Irrigation Scheduler, you will need to record rainfall and irrigation at each field.
  • Location/Weather Data:

    Using your location, the three closest  Enviroweather stations are used to compile data and estimate the Reference Potential Evapotranspiration for the day.
  • Crop Type:

    The type of crop is used to describe how quickly and deep the roots of the crop grow and how much of the Potential Evapotranspiration is used, based on the leaf type and projected leaf canopy cover.
  • Soil Type:

    The soil type controls how water is distributed through the soil profile when rain or irrigation water is added to the crop.  Soils with higher water holding capacities will retain more water, allowing the crop to draw for a longer period of time before exhausting.  Soils with low water holding capacities may allow water to pass through the profile in high rainfall events.
  • Planting Date and Season Length:

    The dates are used to link to the correct weather information, and the season length is used to calculate how mature a crop is on a given date.
