A 200 litre capacity plastic barrel and continuous supply of cow dung and urine (something most farmers have access to) - that's all you need to set up a manure factory in your farm. Cow dung, urine, water and sugar (jaggery is usually used; cane sugar and palm fruit would do as well) mixture is allowed to ferment and settle for 24 hours. The resultant clear micro-nutrient rich solution is used to irrigate the fields. There is no complicated filtration procedure involved and there are no extra costs!
