Heatwave in Argentina will increase stress on corn and soybean crops

Argentina is the world’s second largest exporter of corn after the United States and the world’s largest supplier of soybean oil and flour, Reuters reported. The exchange estimated a record harvest of 57 million tonnes of soybeans and a production of 44 million tonnes of oilseeds.

Since mid-December, much of the country’s main agricultural areas have experienced dry conditions, as temperatures have soared with the onset of summer in the southern hemisphere, reducing yields and raising fears. of losses.

In the coming days, “a prolonged and intense heat wave will start, which will affect most of the agricultural area. Rainfall will remain low to zero in most of the agricultural area,” the stock exchange warned in its agroclimatic report. weekly.

A large area with maximum temperatures close to 40 ° C (104 ° F) will cover the agricultural heartland of the country, the report added.

Extreme weather conditions are striking at a time when 21/22 early sown maize is at key stages of development and yield definition. On Tuesday, the exchange’s chief agronomist warned that due to dry weather, they may have to lower their harvest estimate later.

According to the crop condition and condition report released Thursday, the percentage of good to excellent corn plants fell to 40% from 58% last week, while lots in fairly poor condition rose to 21% compared to 8% the previous week.

The report says dry conditions accompanying high temperatures could cause losses in the 2021/22 soybean area, which planted 86.8 percent complete last week. Planting of maize was 77.3% complete.

Little relief is in sight until the end of next week, when a cold front that would produce moderate to heavy rains between 10 and 50 millimeters (0.4-2 inches) is expected across much of Argentina’s agricultural core. , accompanied by a moderate drop in temperature, the exchange said.

Currently, the La Niña meteorological phenomenon hits the main agricultural regions of Argentina and generates a decrease in the regular level of precipitation. However, until mid-December, the second half had seen steady rainfall rates.
