Soybean producers are hoping for a record crop this year, due to increased planting area and lower input costs than corn.
However, growers fear that lack of rain at the start of the year may have hampered soy crops, during the most critical period of development.
The government estimates that production will be 51.3 million tons, but with climate experts agreeing that favourable weather can be expected, the total production could surpass the record of 52.7 million tonnes in the 2009/10 cycle.
In Argentina, the introduction of corn costs about $490 per hectare, compared to $320 in the case of soybeans.
The price difference for corn responds to higher fertilisation needs and seed is more expensive than soy.
