Agricultural workers in Portugal saw their income drop by 3.2% in 2014 compared to the previous year.
The average across all of the 28 members of the EU was a fall of 1.7%.
Between 2005 and 2014 real agricultural income for workers rose by an average of 34.4%. At the same time, the amount of labour being required fell back by 24%.
The drop this year is likely to be due to the falling profits in agriculture due to lower prices being fetched for crops and meat products.
Significant price decreases were recorded for potatoes (25%), cereal crops (14%), sugar beet (12%), fruits (11%), olive oil (9%), fresh veg (6.5%), and wine (4%).
The lower prices were due in part to an increase in the volume of production, with olive oil up a massive 46% and all the other products were up by between 2% and 7% with the exception of wine where 3% less was produced.
Pork, beef, chicken and eggs also dropped in price.
The biggest drops in pay were in Finland (23%), Lithuania (19%), Belgium (15%), Italy (11%), and Denmark (10%).
Wages in the UK, on the other hand, were up by 7%. This increase was outstripped by three countries, namely Slovenia (13%), Hungary (9%), and the Czech Republic (7%).
