Sri Lanka’s Maha “experiment” to yield uncertain results By Sunimalee Dias View(s): View(s):Sri Lanka is going into the Maha season not knowing the consequences of suddenly adopting organic farming methods. Dr. De Silva explained that they had ascertained the required nutrients by calculating and finding out the requirement of the relevant plant nutrients. The organic fertiliser product imported, he said has a high amount of Nitrogen, Phosphorous and Potassium, which is a real requirement. Traditional compost has 1 per cent of Nitrogen but organic granular fertiliser is between 10-15 per cent, he said. “There will be a yield drop between 21.5 – 33 percent based on scientific research done at Batalagoda (the rice research centre),” he said.
