Egyptian smallholders have seen their lives upended by the war in Iran, with soaring fertiliser and energy prices forcing many to lay off workers and reduce the amount of land they farm.

Before the United States and Israel launched the war that would end up engulfing the region, Ashraf Abu Ragab cultivated a full acre with a small crew.

Now he farms just half on his own after sacking the workers he once relied on, and has quit growing wheat, a fertiliser-intensive crop.

"Everything has become more expensive," the 45-year-old told AFP, standing among rows of maize and sesame in the village of Nazlet Al-Shobak, about 50 kilometres south of Cairo.

"Fertilisers, seeds, chemicals. The crops no longer cover their costs."
