Arkansas Corn and Grain Sorghum Weekly Update – August 14, 2015
Author: Arkansas Row Crops

Corn and Grain Sorghum Update – Dr. Jason Kelley (Wheat and Feed Grains Specialist)

Corn and grain sorghum harvest is progressing and more will be starting harvest this coming week with anticipated dry weather.  Corn yields have been variable so far, but in general are good.  Harvest has been primarily in south Arkansas but will slowly move north this week.

Grain sorghum harvest should expand further north this week as well.  Initial grain sorghum yields have been very good.  Harvest has been delayed on some fields due to the non-uniform maturity.   Stalk rot induced lodging has been seen in several fields.

Corn and Grain Sorghum Research Verification – Kevin Lawson (Corn & GS Verification Coordinator)

Harvest on the corn verification fields has begun. The Lincoln County field was harvested on August 11 and yielded 229 bushels per acre adjusted to 15.5% moisture. The Lee and St Francis County fields should be soon. The Clay – Yount field is still working towards black layer. The rains and cool weather slowed down progress.

Levels of sugarcane aphids increased again this week on the Jefferson County grain sorghum field but still are not at treatment level. We are done with irrigation on both of the grain sorghum fields as we look towards harvest soon.

Southeast Arkansas Update – Wes Kirkpatrick (Desha County)  

Corn harvest is progressing nicely. Yields that I’ve heard about range from 190-240 bu/ac. Grain moisture is below 20% for the most part. 

Central Arkansas Update – Anthony Whittington (Jefferson County)

Harvest is underway in both corn and grain sorghum. Some of the later planted crops are terminating irrigation and will be harvested soon. I am already hearing some good yields in corn for this area.

Northeast Arkansas Update – Stewart Runsick (Clay County)

We received over 3 inches of rainfall over the past week which took care of the final irrigation on many fields. There is a lot of concern over southern rust. Much of the corn was sprayed with fungicide. Most of the corn is at black layer or soon will be.

River Valley Update – Kevin VanPelt (Conway County)

Fields are drying down fast. Producers are expecting to be able to begin harvest next week.

Market Update – Scott Stiles (Economics Specialist)

After yesterday’s beat-down following the August USDA supply/demand report, corn futures are trading around 4 cents higher this morning. Markets were caught off guard yesterday by USDA’s 2 bushel increase in the national average corn yield (now projected at 168.8).  That in turn increased 2015 production to 13.686 billion bushels, up 156 million bushels from the July report. The yield outlook for the western Corn Belt is really impressive this year. Delta yields may be impressive as well as the preliminary yield estimate for Arkansas was a record 195 bushels per acre.

World Agricultural Supply and Demand Estimates Report

NASS Crop Production

With the August supply/demand report released, traders will return focus to the weather and actual yield reports. As harvest moves north from the Delta, more field information will be available to compare with USDA’s August production estimates. The slow pace of new crop exports has been discussed a lot in recent weeks. Compared to a year ago, new crop corn exports have been much slower given the heavy world supplies and stronger Dollar. On the other hand, sorghum exports are well ahead of last year’s pace with China still buying.

The price reaction in corn yesterday was not as violent as that in soybeans. The September and December corn contract held up well considering the shock of the information from USDA. For now, expect corn to trade in price range that is 10 to 15 cents lower for the balance of August. For the December contract, initial support is $3.65 and resistance is $3.75.

August 14 Table 1

This morning’s USDA weekly Export Sales report was neutral for corn prices with sales in line with trade expectations. New crop (2015) export sales for the week ending August 6 totaled 19.76 million bushels, with heavy sales to Mexico. All sorghum sales and shipments were to China last week. For the 2014/15 marketing year the pace of shipments-to-date continues to fall short of the seasonal pace to hit USDA’s export target. It is possible USDA may reduce old crop exports for both corn and sorghum in upcoming monthly reports.

Heat Units  

Heat units continue to be right at the 30 year average.
