High yields and increased acreage has pushed the Buenos Aires Grain Exchange's estimate of Argentina's soybean crop to a record large 45.5 million tonnes. Dry weather last season held production to only 40.5 million tonnes. The group raised their forecast for this crop year by 500,000 tonnes last week due to favorable yields in major soybean growing regions that has boosted productivity to 3.6 tonnes per hectare on average. The Exchange believes that estimate could be exceeded if weather conditions remain favorable through April. As of last Friday, harvest progress was pegged at 9.5 percent complete, which is 1 percent behind last year. Harvesting efforts have been slowed recently by wet weather. Argentina's government is currently projecting a crop of 45.6 million tonnes this year while USDA's most recent number was 44 million.
