Rain hampered soybean-planting efforts in Argentina over the past week.
However, field work still moved forward by 12 percentage points to reach 43% complete as of Thursday, according to the Buenos Aires Cereals Exchange.
Progress in planting the estimated 48.9 million acres is 1.6 points behind last year.
According to exchange analysts, there has been renewed interest in planting soybean in the northern provinces, which if confirmed could prompt an increase in projected area.
Planting moved forward quickest in central parts of the grain belt and early planted beans in the center and south are in "very good condition."
