On Farm Production Of Vermi-Wash
Vermi-wash is a liquid fertilizer collected after the passage of water through a column of worm activation which is very useful as a foliar spray. It contains plant growth hormones like auxins and cytokinin apart from nutrients such as nitrogen, phosphorus, potash and other micro nutrients and also Nitrogen fixing bacteria like Azotobacter sp., Agrobactericum sp. and Rhizobium sp. and some phosphate solublizing bacteria. It acts as a plant tonic and helps to reduce many plant diseases.
The benefits of Vermi-wash are multiple. Apart from acting as a plant tonic, it also helps to reduce many plant diseases and enhances resistance to pest and diseases.. A mixture of Vermi-wash (1litre) with cow urine (1litre) in 10 liters of water acts as bio-pesticides and liquid manure. It improves the rate of photo- synthesis in crop / plant. It helps to increase the population of micro-organisms in the soil and therefore, increases the crop yield. It also enhances the rate of decomposition of compost.
Vermi-wash can be used as a fertilizer before transplanting of seedlings or cuttings. The seedlings before transplanting are dipped in Vermi-wash solution which is diluted 5 times with water for 15-20 minutes and then transplanted. Similarly, the cuttings can also be dipped in the solution. It is effective as a foliar spray. Vermi-wash is diluted in water 5 times and sprayed on the foliage of crops. It provides the plant with vital nutrients and also helps to control plant disease. As a bio-pesticide, Vermi-wash can be used by drenching of soil. Vermi-wash is diluted 10 times with water and the soil is drenched with the solution to prevent some of the soil borne pathogens.
