P&R Surge Systems manufacture two surge valve controllers, the Star and the Jr.III. The Star controller is totally digital and much more flexible in programming. The Jr.III, being the more economic controller, lacks many of the features as of the top of the line, Star controller. If you are using a Jr.III you need to understand . . . → Read More: Surge Valve Update/P&R Jr. III Controller Limitations
This year we are conducting nine rice irrigation Extension demonstration trials across the Delta. To demonstrate the value of maintaining a less than full flood, we are utilizing a Pani Pipe and soil moisture probes to time irrigation events. Research from the International Rice Research Institute reports, that allowing the water level to drop to “Safe . . . → Read More: Rice Irrigation with Safe AWD.
I would like to call this a midseason rice update, but in actuality we have rice in Mississippi ranging from one leaf to late boot in places, but most of the rice crop should be at or reaching mid-season. Similar to 2014, our planting progress was spread out from a typical year. Most of the central . . . → Read More: Mid-Season Rice Update
An agronomic crops field day will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6. The field day will be held in the cotton field on the south side of the road. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean. . . . → Read More: Mississippi State University Turn Row Field Day: Clarksdale, MS July 9, 2015
With the use of irrigation moisture sensors increasing in Mississippi, growers are reporting that their moisture sensor values are remaining high after an irrigation event. Growers are confused and frustrated that irrigation water is just not getting in the ground. Traditional “cotton” soils are classified as sands to silt loams. These soils have a tendency to . . . → Read More: What is going on!
Here are the results of one of our tillage studies where we tilled the middles with a parabolic anhydrous knife at layby in soybeans vs an untilled check. The moisture sensors had been in the ground for a number of weeks prior to the installation of the monitor on June 11th. In the weeks prior to . . . → Read More: Tillage Study on Sealing Soils Results look Promising.
Corn reproductive stages generally comprise about 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions. . . . → Read More: Identifying Corn Reproductive Growth Stages and Management Implications
We have received questions lately reguarding irrigation initiation for corn and soybeans. A couple of tables below detail general guidelines for corn and soybeans in soils ranging from silt loams to heavy clays. Center pivot irrigation field thresholds are approximately 15-20 centibars less than the values presented in the charts. Information on calculating average soil moisture . . . → Read More: Irrigation Guidelines for Corn and Soybeans
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 with surge valves.

If you farm old traditional cotton soils, most likely you have recognized that irrigation water tends to run down the row, racing to the tail ditch. If you have noticed this, you have a “sealing soil”. If you are using moisture sensors to trigger irrigation, and you notice that the sensor values remain high after an . . . → Read More: New Data Available on Sealing Soils
