A study on utilising human urine for agriculture is under process by a doctorate student of Gandhi Krishi Vigyan Kendra.
Using 750 litres of human urine, a scholar by name Sridevi has grown 83 tonnes of maize on 7.3 acres She is also growing 200 banana plants using only human urine as fertiliser.
She says: "Initially, the farmers hesitated. But after seeing the good yield in maize cultivation they are eager to use human urine for cultivation."
It is a known fact that human urine contains an appreciable quantity of nitrogen, phosphorous and potassium which are essential plant nutrients and readily absorbed and assimilated by the crop.
Prasanna, a farmer, says that utilization of human urine yields good crop and saves expenditure on chemical fertilizer.
Around 10 houses in Nagasundra and Swami Vivekananda School near Dodaballapur have adopted eco-sanitation that is eco-friendly toilet. And it's the first time in India a study on eco-sanitation has been conducted.
Developed with the main objective of protecting environment and saving water resources, these eco-friendly toilets are used for recovery of nutrients from human waste to be used for agriculture.
Amrutha, a student of Swami Vivekananda school said that the idea is to grow vegetables for their mid-day meals using nutrients recovered from human waste from the eco-sanitation in the school.
Meanwhile, Sridevi wants the government run school which have mid-day meal system for children, to consider her model for kitchen garden. She has requested the government authorities considering these schools have enough vacant area to adapt her model.
