“Mr. Weatherman, what is your forecast? I need a major change.”
Harvest progress still remains slow at this point without much to update. Still calling
yield reports “solid” so far with most seeming satisfied and only a couple of disappointments.
More rice is very close to being ready, but the slight drop in temperatures and increase
in clouds hasn’t given us the grain moisture drop we need to finish maturing. The
couple of days of lower humidity this week didn’t deliver the heat and sun needed
to go with it.
A number of comments this week of samples being taken thinking rice looked ready only
for it to still be 23-25% moisture. The reality is that when conditions turn favorable,
moisture can drop a few points in just a few days, but it can easily take a week to
drop a few points if drying conditions aren’t good.
The forecast for next week seems to get modified by the minute. While the overall
rain chances look very low, every day is forecast to have very high humidity (100%
overnight!), be partly cloudy, and 30-50% chances of rain. As Harry Hogge in Days
of Thunder said, “this is not the kind of answer I’m looking for from you.”
Let us know if we can help.

Table 1 contains preliminary yield data from 2022 and 2021 planting date studies at the RREC at Stuttgart. Reminder: the 2022 data is preliminary because we haven’t fully analyzed it yet – so it may look
different in its final form presented later this year. Since we start getting questions
about performance data already, we’re showing this now for an ‘early look’. Also
note these were all managed with a conventional herbicide program so that everything
could be included in one trial.

Some phone calls have started coming in asking about the impacts that soybean desiccant
[Gramoxone (paraquat), Sharpen (saflufenacil), and salt (sodium chlorate)] drift will
have on late season rice. In addition, further questions have arisen about the impacts
of potential drift of late season soybean herbicide applications to control grass
escapes (glyphosate and clethodim) will have on rice at this stage.
First and foremost, our goal should be to NOT drift onto neighboring crops regardless
of the potential or lack thereof for injury. Herbicides, particularly systemic ones,
can do some very crazy things from time to time when plants are in reproductive stages.
Minimizing the likelihood for drift (proper sprayer setup, waiting for the right
wind direction, etc.) will help to mitigate potential problems such as yield loss
or reductions in quality that can cause dockages or outright buying point refusals.
In the event that drift does occur onto our rice at this stage from a late season
soybean application to control grasses or desiccate the crop, there’s a couple of
things to watch out for. First, minimal to no visual injury symptoms are typically
observed from drift rates of herbicides when rice is in the reproductive stages. The
results of the drift incident will only be evident once the combine rolls through
When it comes to yield loss, recent research out of Mississippi has shown that simulated
drift rates of Gramoxone (paraquat) can cause some fairly significant yield losses
and reductions in grain fill due to drift occurring anywhere from 50% heading (16-19%
loss) up until one week prior to harvest (5% loss) (McCoy et al., 2021b). Additionally,
seed weight (grain fill) was reduced for all application timings of simulated paraquat
drift except for one week prior to harvest. Simulated drift rates of glyphosate caused
reductions in yield (6-19% loss depending on timing), but no losses in grain fill
occurred at any point from 50% heading to one week prior to harvest. In contrast,
simulated drift rates of Sharpen (saflufenacil) and salt had no effect on rice yield
or grain fill. Additional research suggested that inbred cultivars tended to be more
sensitive or result in more yield loss from late season drift events of desiccant
herbicides (McCoy et al., 2021a).
As we’re nearing the end of the season, and we see the light at the end of the tunnel,
let’s make sure to take care to avoid these drift situations and allow everyone to
finish off on a positive note. Good luck out there!

It was a week of give and take in the rice market. After solid gains Tuesday and
Wednesday for November futures, most of those were given back on Thursday with the
contract closing 16 ½ lower at $17.67 ½. At this writing Friday morning, November
futures are trading 23 cents higher at $17.90 ½. The market is flying blind regarding
exports. But there was plenty to talk about this week on the international scene
with flooding in Pakistan impacting rice and rumors swirling in India over export
Fig. 3. CME Rough Rice Futures, November 2022 Daily Chart.
Overall, the November contract has been in an uptrend since July 5th. Trading may
turn dull in the upcoming week while waiting for USDA’s September assessment of the
crop. If Nov. futures can close above $18, the prospects look better for a return
to the May 16th high of $18.20. That price level will serve as key resistance and more specifically,
a “double top” for the Nov. ’22 contract. Some added attention to marketing decisions
is warranted if the November contract moves into the $18 to $18.20 price range.
The next USDA WASDE and Crop Production will be released September 12th. NASS is in the process of conducting its’ first objective field surveys. One could
argue the market’s rally has been driven by declining yield expectations, which seem
reasonable given the unusual heat this growing season. Furthermore, we could see
some downward revision in rice acres based on the early findings in FSA’s acreage
In the cash market around eastern Arkansas, basis was steady this week. For September
/ October delivery, basis at mills was 23 cents per bushel under November futures.
Mill bids Friday morning were near $7.83. Basis at driers ranged this week from 29
to 36 cents per bushel under November, with bids Friday in the $7.70 to $7.77 range.
In Monday’s Crop Progress, USDA estimated the U.S. rice harvest at 18% complete for the week ending August
28th, up from 15% the prior week. Louisiana and Texas’ harvest had reached 67 and 77%,
respectively. Arkansas was at 4% percent harvested; slightly behind the 5-year average
of 7 percent. Harvest was getting underway in Mississippi with 2% harvested at the
start of the week.

Thursday’s Export Sales report was delayed due to issues with USDA's new reporting system. You may recall
the confusion last week over USDA’s export sales reporting. After the initial release,
last Thursday’s report (8/25) was removed soon thereafter. A few hours later the
USDA issued a statement, explaining that errors in the report were due to the transition
to a new reporting and maintenance system.
Unfortunately, the issues with export sales reporting haven’t been resolved. In a
second statement released August 31, USDA indicated they hoped to have the new system
operational by September 15th. Below is a portion of their August 31 statement:
"As a result of unanticipated difficulties with the launch of the new Export Sales
Reporting and Maintenance System, USDA’s Foreign Agricultural Service will temporarily
revert to the legacy system while we work to fully resolve the issues with the new
system. FAS will be unable to publish weekly export sales data on Thursday, Sept. 1 or
Thursday, Sept. 8, but we expect to resume regular reporting on Thursday, Sept. 15.”

With nitrogen prices pulling back from the spring highs, we get a number of questions
about coverage for 2023. No two years are exactly alike and the current situation
in eastern Europe adds a tremendous amount complexity to forecasting fertilizer prices.
Recently, we ran across an interesting article by DTN contributing writer, Elaine
Kub Best Time of Year to Buy Fertilizer: Seasonal Patterns. Her findings on urea indicate the first week of September has tended to show the
lowest “z scores” or time of year with prices below the season average. In fact,
the period from August to December had negative z scores. We found similar results
constructing a seasonal index of retail urea prices collected by USDA (shown in the
Figure 4. Retail Urea Seasonal Price Tendency, 2014 – 2020.

Industry analysts believe urea prices will remain supported by nitrogen production
outages in Europe. Along with this outlook, some in industry are encouraging growers
to go ahead and book at least a portion (25 to 50%) of 2023 nitrogen needs. To support
this advice, New Orleans (NOLA) urea prices are again working higher, trading in a
range of $560 to $695 to start the week. The prior week’s range was $542 to $578.
Driving this is ammonia, which has increased 15% so far in this quarter. NOLA price
direction generally drives inland urea prices. Phosphate and potash prices at NOLA
and inland were generally flat to lower last week. There seems to be less urgency
to move on phosphate and potash booking for 2023.
Farm Futures released the results of a 2023 acreage survey this week. Indications are 2023 corn
acres will increase 5% and winter wheat acres could increase 7.5%. If true, this
outlook could add further support to nitrogen prices. At this writing, December ’23
corn trades at $6.14 and July ’23 wheat trades at $8.39.
