Introduction

Vermiwash: As a component of INM

Vermiwash, a liquid bio-fertilizer can be collected through the column of activated earthworm.

It contains plant growth hormones like auxins and cytokinin apart from nitrogen, phosphorus, potash and other micronutrients.

Benefits of Vermiwash

Vermiwash acts as a plant tonic and helps to reduce many plant diseases

A mixture of vermiwash (1litre) with cow urine (1litre) in 10 litres of water acts as bio-pesticides and liquid manure.

Vermiwash: As a component of INM

  • The trickling of water takes away all the body secretions of the earthworm along with it and also other nutrients from the decomposed materials.
  • The collected water contains many nutrients readily available to the crop plants.

Vermiwash: As a component of INM

Introduce about 2000 earthworms into the container.

A base layer of gravel or broken small pieces of bricks are placed upto height of 10-15 cm.

On the coarse sand layer place 40-45 cm pre-decomposed organic wastes and moisten the different layers by using water.

Precautions

Vermiwash: As a component of INM

Water should be poured slowly.

Do not mix un-decomposed material while, watering.

Do not add any green material.

Do not allow to compact the contents.

Vermiwash: As a component of INM

Vermiwash, a liquid fertilizer collected after the passage of water through a column of worm activation is very useful as a foliar spray.

It contains plant growth hormones like auxins and cytokinin apart from nitrogen, phosphorus, potash and other micro nutrients.

It contains nitrogen fixing bacteria like Azotobacter sp., Arobactericum sp. and Rhizobium sp. and some phosphate solublizing bacteria.

It acts as a plant tonic and helps to reduce many plant diseases.
