This summer we had multiple conversations with producers that either irrigated or had significant rainfall events on their field, but the soil moisture sensors below the 6 inch depth never “detected” the irrigation or rainfall event (see http://www.mississippi-crops.com/2014/06/26/is-my-soil-moisture-sensor-broke/ ). The producer assumed the sensors were “broke”, but we attributed the phenomenon to “surface sealing”.

This week we encountered another issue with a surge valve. After irrigating with a surge valve the producer noted that neither the 6” nor 12” sensors responded to the irrigation. When investigating the problem it appeared that the grower had done as instructed, making the proper adjustments to the advance cycle. What’s going on? Further investigation . . . → Read More: Another Surge Valve Experience!
Southern corn rust continues to be observed throughout MS. We continue to receive calls regarding late fungicide applications (> R4/R5) to reduce yield losses attributed to southern rust. Numerous myths regarding the disease have been widely spread throughout the MS corn production area including death of a corn plant in as fast as 7 days following southern rust infection and lodging as a result of heavy southern rust infection. . . . → Read More: What Should You do about Late Southern Corn Rust?

“It ain’t over till it’s 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 . . . → Read More: “It ain’t over till it’s over!” / Turnrow Talks
This past week we encountered the following situation. A Grower irrigated a silt loam field utilizing a surge valve. When he checked his moisture probes neither the 6” nor the 12” Watermark™ sensor had moved. What’s going on? After careful evaluation we realized that the grower had prematurely terminated the irrigation cycle.
A few weeks ago we . . . → Read More: Surge Valve Issues and Gleanings.
It’s okay to let it down!
Defining proper flooding of rice can be somewhat challenging depending who you talk to. One thing is for sure, to take advantage of the cost saving of straight levees and multiple inlet rice production, the depth of flood has to be managed. With the days of cheap water behind us and . . . → Read More: It’s okay to let it down!
Now is the time to prepare for 2015 PHAUCET implementation!
Without a doubt the installation of PHAUCET (Pipe Hole and Universal Crown Evaluation Tool) on every acre of your farm is the most important water saving strategy you can implement. PHAUCET allows you to irrigate your fields uniformly with each furrow watering out at . . . → Read More: Now is the time to prepare for 2015 PHAUCET implementation!
Bollworm trap counts were higher in Lowndes county this week, but all other locations were similar to the previous week. Tobacco budworm catches remain at very low levels throughout the state. Southwestern corn borer counts were also very low throughout the state. Moth catches may have been somewhat depressed this week due to the frequent rains . . . → Read More: Insect Trap Counts, June 13, 2014
