“It ain’t over till it’sJason Surge over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in the season. With harvest for corn and rice  within 30 days, does it make sense to lay the investment?

Eric Larson, Extension Grain Specialist, recently published an article on the Mississippi Crop Blog concerning termination of corn irrigation. http://www.mississippi-crops.com/2014/07/03/will-we-need-to-irrigate-our-corn-again/ Examining the milk line migration is the determining factor in corn irrigation termination. If the milk line has progressed to the ½ way point and your soil profile is recharged after last week’s rainfall, most likely irrigation is not warranted.

Most of the area’s soybeans are in the R4 Stage or earlier and have a long way to go before terminating irrigation. Trent Irby, Extension Soybean Specialist, says, “With our hottest, driest month of August ahead of us, no doubt we will need to irrigate”. Most studies confirm a yield loss of 10 bushels when irrigation is terminated before R6 (soybeans are touching and completely fill the cavity). With soybeans in the $11.00 range, laying the pipe is a good investment. Dr. Irby’s Soybean termination article can be found here. http://www.mississippi-crops.com/2013/09/04/soybean-irrigation-termination/
