Urine is fertilizing crops and saving money in India, by Robert Goodier, Engineering for Change, May 2011.
Consider these facts about urine: Adults produce about four to eight cups (one to two liters) per day, it’s a reservoir of nitrogen, potassium and phosphorus, the same elements that nourish crops; and it’s cheap to make.
That’s the kind of information that Sridevi Govindaraj, an Indian agriculture expert, had in mind when she proposed that dousing fields with urine could improve sanitation and boost farmers’ incomes.
“Human urine is indeed not an unwanted waste, but it is a useful resource,” Sridevi wrote to E4C.
