September started with a rainy event that was not in the plans, will it continue like this?
The overall region received 25mm on average. They are the first major rains 4 months of drought. But these rains have been an event with very unusual characteristics. To begin with, the rainfall values recorded tripled what the models indicated. Besides, there were no significant humidity circulations in the previous days and they occur without the auspices of the great oceanic forcing. Also, it was an event that took place in almost 3 days of very mild rains, ideal for infiltrating every millimeter into the ground. This behavior is more typical of November than this time, away from violent storms and accompanied by hail, as happened in the previous week. Another noteworthy data is that taking together the rains of the last two weeks (8/24 to 8/31), Chacabuco reached 115 mm, Junín 84 mm, and Rufino 70 mm. Hitting records for that period. Will this type of event be repeated? The cooling in the Pacific continues to deepen.
Will the rains be enough to save the plots about to be lost?
Between the lack of water and the frosts, a million hectares of wheat were between fair and bad conditions. 200,000 thousand hectares were on the verge of being lost. This week will be evaluated according to the recovery that is observed in how many batches are going to be dried to pass to soybean. In many localities, farmers say that at least 5% of the planted area has already been lost.
Technology and management, the keys to future wheat recovery.
It is very difficult to know what can happen to the harvest this year. In almost all areas, they estimate losses ranging from 10 to 30%. But after the discouragement, the technicians bet on the recovery and yield acceptable if the supply of water recovers from here on. This is possible due to the change that occurred in the way of making wheat in the region. There are many lots that are very advanced and the tillering has already been played: 65% of the region is in the pipeline. But for 5 years, the handling of wheat is different and now the plantings are done with high densities to put aside what may happen to the tillers. The other key is fertilization and how quickly the crop can regain the foliar area.
The rains activate the preparations for planting corn.
Fertilization of the batches for maize planting will begin next week. Some want to start without delay on September 15, others will wait for new rains of 20 to 30 mm to cheer up. The moisture analysis of the profile of some batches reveals that the water shortage is in the first meter and that these rains begin to discount the millimeters that the cereal is missing. In the areas with the most deficit, they warn that if the rains in September and October do not accompany them, some will switch to first-class soybeans or will decide to make a late maize in December. For now, the intention to plant maize in the core region maintains a 7% drop compared to the 2019/20 campaign.
