Vermiwash is a very good
plant tonic which can be used for
foliar spray. Vermiwash units can be set up either in barrels or in buckets or even in small earthen pots. It is the principle that is important. An empty bucket with one side open is taken. On the other side, a hole is made to accommodate the vertical limb of a ''T'' jointed tube in a way that about half to one inch of the tube projects into the bucket. To one end of the horizontal limb is attached a tap. The other end is kept closed. This serves as an emergency opening to clean the ''T'' jointed tube if it gets clogged. The entire unit is set up on a stand made of few bricks or wood to facilitate easy collection of vermiwash. Keeping the tap open, a 25 cm layer of broken bricks or pebbles is placed. A 25 cm layer of coarse sand then follows the layer of bricks. Water is then made to flow through these layers to enable the setting up of the basic filter unit. On top of this layer is placed a 30 to 45 cm layer of loamy soil. It is moistened and into this are introduced about 50 numbers each of the surface (epigeic) and sub-surface (anecic) earthworms. Cattle dung pats and hay is placed on top of the soil layer and gently moistened. The tap is kept open for the next 15 days. Water is added every day to keep the unit moist. On the 16th day, the tap is closed and on top of the unit a metal container or mud pot perforated at the base as a sprinkler is suspended. 5 litres of water (the volume of water taken in this container is one fiftieth of the size of the main container) is poured into this container and allowed to gradually sprinkle on the barrel overnight. This water percolates through the compost, the burrows of the earthworms and gets collected at the base. The tap of the unit is opened the next day morning and the
Vermiwash is collected. The tap is then closed and the suspended pot is refilled with 5 litres of water that evening to be collected again the following morning. Vermiwash is diluted with water (10%) and sprayed on plants to function as an effecting foliar
spray and pesticide.
