Argentina's arable land is just 27% of what the USA has. Fact-checking myself... the USA has more arable land than Canada, Australia and Argentina combined. Russia has a lot, but the USA has the most. https://en.wikipedia.org/wiki/List_of_countries_by_arable_la...

Not sure where to find an aggregate growing days figure, but there's clearly less of them per arable surface area in Canada compared to the USA.

Honestly if other countries did the same stuff as Argentina they'd probably be way worse off than Argentina as the country is still relatively wealthy. They were arguably too rich (and not populated enough with 4 million people in 1900) for a while making industry, especially export oriented industry, less viable sort of like dutch disease.
