1/ #Argentina: Showers provided timely moisture for winter grains in Buenos Aires, while heavier rain fell in the northeastern #cotton belt.  According to the gov't of Argentina, as of Sept. 30, #corn was 17 percent planted versus 19 percent last year.


2/ #Wheat development ranged from vegetative in the south to filling in northern farming areas, many of which need moisture.

Crop calendar for Argentina:

FAO GIEWS Country Brief on Argentina -




#Argentina's #soybeans are most concentrated in Cordoba, Santa Fe & Buenos Aires. The 2020/21 crop is pegged @ ~50 mln tonnes (1.84 bln bu). That is roughly the estimated 2020 crop of the U.S. I-states plus Minnesota. Speaking of, they fit quite nicely in Argentina's grain belt.

Planting of #soybeans in Mato Grosso, #Brazil, is favorably quick so far. As of Friday, 45% had been planted, above last year's 8% and avg 26%. Planting had progressed at a similarly fast pace in 2018 (for 18/19 crop). 2019 was also fast, but 2020 started very slow.

Planting of #soybeans in Mato Grosso #Brazil continued at a quick clip last week, reaching 69% complete on Friday. That is far ahead of last year's 25% and the 5yr average of 41%. This is the type of planting season farmers would want - slow threatens the second corn crop.

All of Argentina to get less than half the average rain the next 2 weeks. This is bullish weather for the beans at some point if it isn't now already. However, almost  ALL of Brazil gets massive rains which is  bearish weather(a bit too much in C. Brazil)..........but its still early in the season too. They are still just planting. If the pattern is still like this in a month, I think we will attract fund money into buying. But its weather........and often changes.

La Nina Arrives; Looks Like La Nina Modoki

The most recent La Nina Modoki events were early in the year of 2008 and 2012. Briefly, La Nina Modoki occurred in early 1989. The climate bias of La Nina Modoki during those few analog years was a wetter winter climate for Texas to the Mid-south U.S. compared to normal La Nina, wetter for Brazil and Argentina compared to normal La Nina and in Australia the wet bias was across the northwest, north and East Coast.

There's a bit more rain in the 2 week forecast in the dry spots of Argentina and S. Brazil here on Sunday than there was last week. However it's still only half the average. Those areas need the light blue color to completely cover them up for the forecast to be at least 2 inches of rain. Soils are more porous in SA/don't hold water as well, so they actually need a bit more rain than we do.

Thanks Jim,

I stay up late until the 0z models are completely out much of the time, which ends with the European ensemble model around 2am Central/my time. 

Sometimes I'll post the updates here then, especially if its a change and I'm in my office.

Not so if I'm in bed on my Ipad(that can't do that). 

Sometimes, in my bed on the Ipad, I'll fall to sleep during the European model and wake up an hour later. 

I will also wake up by alarm at 5:30a to get the next run of the GFS when the markets are reacting to every model run and I have a position on. 

Lately, I've been getting lazy and the markets have been gyrating with wild spikes in both directions, sometimes against the right direction/move so that its like riding a bucking bronco that throws you off every time (-:

But getting more sleep!

Can you tell if the Argentina/S.Brazil weather is bullish(-:

IMO this rally should have happened earlier based on the weather models and previous, similar situations.

The GFS is suggesting possible rains CHANCES after day 10 after no rain and blistering heat at times and this is like late June for us in the Northern Hemisphere for them down there.

The only way I would short is if we come in one day with a massive rain event and pattern change thats closer than this.

Rain chances are increasing at the very end of week 1, so the easy money for the bulls has already been made. These are 2 week rain totals below. Still below average and we need at least bright blue(2+ inches) to really help but 1-1.5 inches is better than no rain.

Exactly Jim! Better, drought tolerant varieties but the always overlooked part..........increasing CO2 causes plants to be more drought tolerant.

They have stomata on the underside of their leaves that open up to pull in CO2.

At the same time, they lose water from transpiration. With elevated levels of CO2, they don't need to open their stomata as wide and thus, have less transpiration and conserve moisture........optimize water use efficiency.

San Del Estaro in the northern growing region of Argentina has a current temperature of 108 degrees and its been that hot all week. It only produces around 5% of the crop but that crop is either  dead or gone dormant waiting for rains. The beans can do that. I watched it happen in 2012.

The corn is dead there.

Cordoba, which is the highest producing area in the central district has been up close to 100 all week.

All with low humidities and winds this week.

And is hasn't rained for a couple of weeks and was dry before then.

Argentina will have the lowest yields in decades. Extremely high confidence. I don't ever remember weather like this there the last 2 decades.

Some of this weather has affected S.Brazil which has also been burning up with no rain.

Some places in Central Brazil have had too much rain.

Rain chances coming next week to the dry spots put pressure on beans the last few days.
