Argentine farmers plan another strike

BUENOS AIRES, Argentina (CNN) - Two months after resolving the most contentious crisis of her nascent presidency, Argentine President Cristina Fernandez de Kirchner is again being challenged by Argentina's powerful farming sector.

Argentine agricultural leaders on Tuesday announced plans to strike this week in protest against rising costs throughout the country.

Argentine Rural Society President Hugo Biolcati told reporters farmers will not sell grains from Friday until Wednesday.

"The situation has gotten worse recently for farmers," Biolcati said. "The agriculture secretary knows the situation that we are facing, and didn't offer any sign of wanting to move talks forward... that is why we have decided to protest again."
