South American Cold Wave: Brazil Looks for Crop Damage 

This time last year South America felt the damage, not from heat as the media so intently focusses on but ice;

As any one who grows anything knows frost is a killer and is not what the world’s largest producer of Arabica coffee needs;

The media will continue to focus on heat and ignore the cold. It wasn’t heat in 1994 that raised coffee prices

It’s not exactly been a good year for Chile either;

Although the uncertain at this point the initial prospects look okay, in part due to previous severe frosts changing behaviour – something those of us told to plant with the Mediterranean in mind would do well to follow [my emphasis];

Citrus Committee president Juan Enrique Ortúzar told Fresh Fruit Portal there had been no initial reports of major damage to crops.

“A big help was that the soil was damp as there’s been a lot of rain recently, and that functioned as a preventative measure,” he said.

He added that many growers had invested heavily in wind machines, which also helped to avoid frost damage.

Another point he mentioned was that over the years growers had been changing the crops they grow in the areas that were more exposed to the cold, planting more resistant crops like peaches and walnuts.

as a result of many years of severe frosts, the industry had also been relocating avocado orchards away from the higher risk areas.

Frost damages pastures, vegetables and fruit

Tuesday (17) dawned with thermometers marking negative temperatures in several municipalities in the Southern Region and also in southern Mato Grosso do Sul. The National Meteorological Institute (INMET) registered negative temperature in at least 40 cities. There has been frost formation in wide areas.

Frosts reached sugarcane plantations in Mato Grosso do Sul, as well as wheat crops in western Paraná. However, it is still early to evaluate the real losses that this cold caused in these crops. In addition to wheat and sugar cane, pastures, vegetables and some fruit were also hampered by these record temperatures.

At dawn only the stations on the coast of Rio Grande do Sul and Santa Catarina had a positive temperature, according to INMET data. From southern Mato Grosso do Sul to Campo Grande, from Foz do Iguaçu to Londrina, temperatures were below 4ºC.

That is, it may have frosted throughout this large area and the risk continues in the next 4 days.

Of course it will warm up during the day, what will remain as a souvenir of this cold is dry air, which must mistreat the pasture a lot and increase the risk of fire in the field, whether intentional or not.
