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”.

Plan to attend an upcoming Irrigation Termination Turnrow Talk on August 26, 2014 sponsored by the Mississippi Soybean Promotion Board, Mississippi State University Extension Service, and stakeholder organizations of the Delta Sustainable Water Resources Task Force. Soybean producers will have the opportunity to learn how to determine the right time to end irrigation for the season . . . → Read More: Reminder: Soybean Irrigation Termination Turnrow Talks – August 26, 2014
We have reached the point of the growing season where we have begun to terminate irrigation in soybean. When making this decision, the goal is to make sure that adequate soil moisture is available to ensure that the soybean seeds reach maximum size. Terminating irrigation too soon can result in decreased seed size which ultimately will . . . → Read More: Soybean Irrigation Termination
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!
We are having lots of questions concerning the proper set up of surge valves. First, please consider some of the basic terminology associated with furrow irrigation.

According to the USDA National Agricultural Statistics Service in Mississippi, 89% of the soybean acreage is planted as of the week ending June 8, 2014. At this time, 82% of the crop is emerged. The remaining acres to be planted will mostly consist of double-crop soybean behind wheat. At this time, Mississippiâ€™s soybean crop ranges from . . . → Read More: Soybean Crop Update and Replant Decisions
On June 9, leaders from the Mississippi Soybean Promotion Board, key personnel from the Mississippi State University Extension Service, and stakeholder organizations a part of the Delta Sustainable Water Resources Task Force formally announced a series of summer irrigation â€œTurn Row Talksâ€ to be held across the Delta during the month of July for producers to attend local, on-farm demonstrations of water conservation efforts being implemented and utilized by growers in their respective areas. . . . → Read More: Delta Area “Turn Row Talks” on Water Conservation Announced
The soybean crop ranges from still in the bag to around V5 stage on average across Mississippi. Over the last 10 days I have received numerous calls (mostly from Delta region) about bollworms attacking vegetative stage soybeans. Arkansas has also reported high numbers of bollworms in soybeans. In fact, AR has some fields where bollworms are infesting emerging soybeans in the crook stage and eating them to the ground where vegetation was present during planting. . . . → Read More: Bollworms Plentiful in Young Soybeans
We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met. . . . → Read More: New Neonicotinoid Pollinator Protection Labels
