Abstract

AbbreviationsFUCREAUruguayan Federation of Regional Consortia of Agricultural Experimentation (using its Spanish acronym)GPgross productA huge increase in land under agriculture has occurred in the Rio de la Plata region since 2002 driven by the increase in prices of grains. Annual cropping systems increased by 6.2 million ha since 2012, including soybean [Glycine max (L.)

Soybean is the dominant crop in this entire region representing 63% of the total cultivated area vs. 19 and 12% of maize and wheat, respectively (FAOSTAT, 2016).The area of soybean was the one that grew the most in the region (Paruelo et al., 2006).
