Brazil's 2017/18 soybean planting window opened in Parana on Sept. 10, but producers have held off sowing because of extremely dry weather and no rain in the forecast.
Some farmers who planted early are worried about how the young crops will develop.
Delayed planting in Brazil's main export region lifts expectations of later and possibly smaller soybean supplies, which supports soybean and meal prices.
