Dryness has blighted Pampas since mid-2020, prompting the Buenos Aires Grains Exchange last week to cut its soy and corn harvest estimates. Soy and corn are Argentina's main cash crops.

In Argentina, the Buenos Aires Grains Exchange on Thursday cut its 2020/21 corn crop forecast by 1 million tonnes to 46 million tonnes, citing lower-than-expected yields caused by dry weather.
The US Department of Agriculture's Buenos Aires office last week projected the corn crop at 47 million tonnes, a half million below the agency's official estimate, due to drought damage.
