Brazilian soybean farmers had finished 30% of their planting work for the 2017-2018 season as of Oct 26, according to agricultural consultancy AgRural.

That’s in line with the five-year average of 31% for the date, though behind the 41% on the same date last year, AgRural said. Planting is advancing rapidly in the south, but scarce or irregular rain in the center-west is slowing planting in that region.

In the state of Goias, only 6% of planting has finished, compared with the five-year average of 28%, according to AgRural. In Mato Grosso state, Brazil’s biggest producer of soybeans, there was more rain last week, and planting advanced to 43% finished, compared with the five-year average of 45%.

The weather forecast for the center west is for a good volume of rain in the beginning of November, AgRural said.
