After a number of years of disappointing sugarcane yields and low prices, some farmers in Sao Paulo have decided to plant soybeans instead of renovating existing sugarcane fields. Sugarcane production in Sao Paulo, and in Brazil in general, has suffered in recent years due to recurring droughts and even freezing temperatures. Prices for sugarcane have been low as well due to poor sugar and ethanol margins for the region's sugar mills.
