(NDAgConnection.com) – A deal aimed at easing global food shortages by helping Ukraine export its agricultural products from Black Sea ports was extended for four months on Thursday, though Russia said its own demands were yet to be fully addressed.

According to Reuters, the agreement, initially reached in July, created a protected transit corridor and was designed to alleviate shortages by allowing exports to resume from three ports in Ukraine, a major producer of grains and oilseeds.

Argentina farmers could reduce the area they plant with soy if more rain does not bring relief to drought-plagued farmlands soon, the Buenos Aires grains exchange said Thursday as it forecast moderate showers in parts of the country’s farm belt.

Meanwhile, Chicago wheat futures rose for the first time in three sessions, although the market is on track to end the week in a negative territory as an extension of the Black Sea export deal eased concerns over global supply.
