Argentine farmers' groups are promising more protests following failed talks with government officials Thursday over increased export taxes on soybeans and other grains.

The talks marked the second time since March that both sides started talks to try to resolve the dispute. One farm leader was quoted as saying farmers felt disappointed after the negotiations, but Argentine Cabinet Chief Alberto Fernandez said he thought the meeting had been productive.

President Cristina Fernandez de Kirchner announced the increase in March, prompting farmers to stage a three-week strike that disrupted grain shipments and caused food shortages.

The farmers suspended their strike in April to negotiate with the government but then staged another protest this month over the government's agriculture policy. They have now called for demonstrations on May 25 - which is Revolution Day in Argentina - to protest the policy.

President Fernandez has said the increased taxes will be used to help the poor.
