"A blessing" for Argentine farmers: They welcome rain but are still concerned about harvest risks

Juan Solari weaves between rows of corn in Chivilcoy. He brushes past yellowing leaves, and smaller ears, which are a result of the heat and lack rain of January in Argentina's Pampas plains. Argentina, which is one of the top food exporters in the world, was on track to have a record-breaking corn harvest for the 2025/26 year. However, unusually high temperatures in January, with some areas reaching 35 degrees Celsius, coupled with low rainfall, caused crops in Argentina's agricultural heartland to be stressed.

The Buenos Aires Grain Exchange lowered its estimate of Argentina's grain production to 57 millions metric tonnes on Thursday, from a previous prediction of 58million metric tons. The exchange has yet to publish an updated outlook on the soybean crop. Farmers welcomed the rains that fell on Wednesday and Friday, even though they were not enough to quench scorched plants. Solari hopes that the light rains will continue to bring relief to his fields.

Solari, who is also a partner in the Emidelia Solari Ranch and its manager, said: "It’s a blessing." It changes expectations."

Since Wednesday, the ranch near Chivilcoy (about 160 km from Buenos Aires) has received only 25 millimeters in rain -- far less than he hoped.

Solari, who was surrounded by the stench of damp earth, said that the crops which were planted earlier, such as corn and soybeans, had started out very well. But when January came, a month with a relatively dry climate, the crops were negatively affected.

"Now, the game is in February. If the rains continue to fall consistently, we will be able to maintain a very high potential," he said.

According to the Buenos Aires Grain Exchange, the soybean planting cycle for 2025/26 has ended in Argentina and the corn harvest is now underway.

The U.S. Department of Agriculture estimated Argentina's corn harvest at 53 million tonnes and its soybean harvest to be 48.5 millions tons for 2025/26.

German Heinzenknecht is a climate expert at Applied Climatology Consulting. "The rain slows down the current deterioration but it's still not a solution," he said. The harvest is still in danger, it's a critical situation that will heavily depend on what happens.

Heinzenknecht says that Argentina's central agricultural belt could begin to recover next week if it receives more than 50 millimeters in rainfall.

DISPARATE REALITIES

The recent rainfall in Argentina was uneven, bringing joy to some and causing anxiety for others. Farmers are aware that without additional precipitation, their crops will quickly deteriorate.

"These nine or ten millimeters - that have just fallen - alleviate a little the expectations we may have, as the drought appears to be over," said Eduardo Caruso, of the Santa Ana Ranch in the town Navarro in Buenos Aires Province, where he grows corn, soybeans and livestock, among other things.

Caruso's field showed signs of dry and cracked soil even after rain. This underscored the need for more rainfall. He predicted that his corn yields would drop to 7 tons per hectare from 12 tons per hectare earlier.

Similar calculations are made by other farmers.

"Everything went well?up until December 20. "In January, it rained, but the days were hot," said Jorge Bianciotto. He is the manager of La Lucila Ranch in Pergamino.

Bianciotto predicted that the yields of early planted corn on his farm will drop by 30 percent to 7 tons per ha, and soybean yields will also fall about 30 percent to 3.3 tons.

Next week will be critical. "If it doesn't pour, things will get complicated," said he. Reporting by Nicolas Misculin; editing by Cassandra Garrison, and editing by Chizu Nomiyama
