How much Nitrogen have I Lost from Saturated Soils?
Abundant rainfall has soaked corn fields for extended time during April and late May, exposing nitrogen fertilizer to potential loss. This article gives guidelines for estimating potential N loss.

What is Appropriate Timing for the “Tassel Shot” on Corn?
More growers are implementing different “tassel shot” inputs as part of their corn management program. Wet weather and other issues may further complicate application timing of such inputs. This article discusses whether specific timing makes a big difference or not?
Tire Traffic Soil Compaction Effects on Corn
As a lot of our corn approaches tassel, issues associated with tire traffic soil compaction are becoming more evident. This article discusses the consequences.
Reminder: Scout Schools Start Next Week
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and
When Should I Start Irrigating My Corn?
The recent stretch of dry weather has prompted much conversation about the proper time to initiate irrigation for corn. This scenario usually generates a lot more anxiety than necessary because early season wilting is certainly not something we are very accustomed to.
Managing Stink Bugs in Seedling Corn
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva.
Use a Sound Corn Nitrogen Strategy to Combat Rainy Weather
Abundant spring rainfall can create havoc with corn nitrogen management by delaying fertilizer application and also promote massive nitrogen loss. These strategies should help enhance crop response during challenging conditions.
High Stink Bug Numbers Being Reported in Some Heading Wheat Fields
Calls are starting to come in about stink bugs in heading wheat. It is not uncommon to find numerous stink bugs in wheat after head emergence. Species attacking wheat are typically rice stink bug and brown stink bugs but greens can sometimes be found. While it may seem very alarming, keep in mind it takes extremely high numbers to cause economic damage to heading wheat.
Mississippi Crop Progress and Condition Report – 4/19/15
According to the National Agricultural Statistics Service in Mississippi, there were 1.8 days suitable for fieldwork for the week ending Sunday, April 19, 2015. Topsoil moisture supplies were 0 percent very short, 1 percent short, 37 percent adequate, and 62
As Crops Emerge, Slug Calls Start
I have recently received a few call about slugs in corn and soybeans. I suspect this will increase when more crops emerge in the Hill region of the state as well. Slug problems usually start on corn first, then move to soybeans, then cotton in our area. This is only because we typically plant in this order. Slugs have been a sporadic problem in MS row crops over the years with increased occurrence since 2004. This has been exclusively a no-till or reduced till problem, particularly no-till behind a grass crop like corn or grain sorghum. Cool wet years are particularly favorable for slug problems to develop.
2015 Scout Schools Set for Mississippi
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all major row crops, and fertilizer characteristics. CEU’s Provided: Nutrient Management = 1.5, Integrated Pest Management = 3, Crop Management = 1
Are We Going to Get this Corn Crop Planted?
Much like the last 2-years, as rains delay corn planting progress, more concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states new guidelines for late corn plantings based upon recent MSU research.
Seed Treatments, In-Furrow Sprays, and Granular Insecticides: What to do in Mississippi Field Corn
Although every major field crop we grow in Mississippi is responsive to at planting insect protection; field corn is perhaps the most consistent. Why is this?
Auxin Herbicide Plantback Restrictions
There are a multitude of 2,4-D and dicamba formulations labeled for application to agricultural fields.
Pipe Planner Instructional Videos
“Pipe Planner is a free, user-friendly, web based application designed to help farmers create the most efficient poly tube irrigation system for their crops,”says Chris DeClerk of Delta Plastics. To assist Mississippi growers in the implementation of Pipe Planner, Lee
2015 Delta Ag Expo, Cleveland, MS – January 21 and 22, 2015
Find attached the agenda for the 42nd Annual Delta Ag Expo to be held in Cleveland, MS on Wednesday, January 21 and Thursday, January 22, 2015. We hope to see you in attendance at the Bolivar County Ag Expo Center.
Lower Cost for Poultry Litter Analysis in Mississippi
Earlier this year the Mississippi State Chemical Laboratory lowered the fee for poultry litter analysis. Nutrient content of litter used for fertilizer varies up to 60%. Crop producers should have a recent analysis of litter so appropriate land application rates
2014 Corn Hybrid Demonstration Program Results
The MSU Corn Hybrid Demonstration Program evaluates superior corn hybrids from numerous seed companies who market corn in Mississippi. Our objective is to provide you more opportunity to evaluate premier corn hybrids and substantially supplement the independent and unbiased information gathered in the University Hybrid Trials.
2014 Row Crop Short Course – End of Pre-Registration
The 2014 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University on December 1-3, 2014. Attendance is free of charge if you pre-register. Pre-registration is available until November 26. Registration
Preparing for Flow Meter Reporting Deadline
We received a phone call this morning from a Delta grower requesting assistance with his flow meter readings. Before the weather turns wet and cold, he had decided to collect the data from his well’s flow meters for reporting by
2014 Row Crop Short Course Preliminary Program
The 2014 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University on December 1-3, 2014. Attendance is free of charge if you pre-register. Pre-registration is available until November 26. Registration
2015 MSU Short List of Suggested Corn Hybrids
This effort lists those corn hybrids which have demonstrated superior productivity in the MSU Corn for Grain Hybrid Trials. Approximately 80 corn hybrids representing the vast majority of seed companies in the Mid-South participate in the MSU hybrid trials. This information should help you better assess corn hybrid productivity and improve your success in future seasons for either irrigated or dryland culture.
2014 Row Crop Short Course
On behalf of the Mississippi State University Extension Service, we would like to cordially invite you to attend the 2014 Row Crop Short Course to be held at the Bost Extension Center on the campus of Mississippi State University from
Identifying Soils that “Seal” and Improving Irrigation Application Efficiency in “Sealing” Soils
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 https://www.mississippi-crops.com/2014/06/26/is-my-soil-moisture-sensor-broke/ ).
When is it safe to Apply a Grain Sorghum Harvest Aid and what to Expect?
Many growers in the Mid-South apply a herbicide shortly prior to sorghum harvest to facilitate combine efficiency and suitable grain moisture. This season, this issue is even more critically important because of severe harvest problems potentially created by White Sugarcane aphid infestation. This article will discuss appropriate timing and potential outcome of such harvest aid applications.
