At a government-run warehouse at Barabanki, 30 km from Uttar Pradesh's capital Lucknow, 23-year-old Lav Kush is one of the few farmers who has turned up with enough usable currency for two sacks of fertiliser. This fertiliser is critical for the potato crop that he's just sowed on his two acre-field. He'll need more fertiliser soon, but Lav Kush is already out of cash.
