Walker’s Story Part II: Planning an Irrigation Schedule with FarmLogs Rainfall Tracking

April 13, 2017

In Part I of this series, Louisiana farm manager Walker Thurmon wrote about his experience using FarmLogs GDD to track the growth stage of his corn crop. In Part II, Walker writes about using FarmLogs Rainfall Tracking to plan his irrigation schedule.


Irrigation and FarmLogs Rainfall go hand-in-hand

Having the ability to assess daily rainfall on every one of our fields from the office or sitting in the truck makes keeping track of rainfall a breeze and makes checking rain gauges an unnecessary task. Not only do we know how much it rained to the nearest one hundredth of an inch, but we can tell within what two-hour window it rained.

When I received the rainfall to the nearest hundredth, I thought to myself, "There's no way," but I checked the rainfall estimate in FarmLogs and it was within 3 to 4 hundredths every time.

Using rainfall data is vital for planning irrigation scheduling. I'm currently using Louisiana State University's Ag Irrigation Schedule, created by Stacia Davis. FarmLogs provides me with the data I need to put into our local irrigation scheduler, which in turn combines rainfall, heat, evaporation, soil data and crop coefficients to schedule the next effective irrigation. FarmLogs gives growers the ability to be precise in irrigation applications. You can use surge values, moisture sensors, etc., but ultimately you need to have the data.

If you have data to make decisions on it's going to make you feel a lot more confident in those decisions. Then you'll be able to do a lot more analysis at the end of the year. 

FarmLogs not only has the data, but has the right data. I recommend everyone use it!

More Information: How does the Rainfall Tracker work?

Our rainfall history and tracking comes from a dataset that the National Oceanic and Atmospheric Administration (NOAA) produces. The NOAA sources the data from multiple radar and ground stations to algorithmically calculate the amount of precipitation that falls on a high-resolution grid across the continental United States. The NOAA factors in variables like wind and terrain that influence where the rain actually hits the ground. This is done within 0.62 miles (1 km) of accuracy. The rainfall grid data is gauge-corrected every hour, after which we check for updates and match them up with your field boundaries.
