Post Tips How To Make Vermicompost
by: Rohit Rathore





COMPOST PITS :

To begin with one compost pit would be ideal for every 100 ha plantation. The method of preparation of the compost in the pit is as follows :

Dit a pit of 10 M X 5 M and 1.20 M depth. Make leaf litter and twigs available in the plantations into pieces. Organic waste like agricultural residues, vegetable market waste, cow dung, farmyard manure, sugarcane bagasse can be filled up in layers. Apply cow dung slurry and area solution. A thin layer of local soil over each layer will provide the required soil microbes. Cover the pit with soil. Wet the pit periodically to facilitate early decomposition. Decomposition process may take 45-60 days. Fully decomposed material is warm and does not omit bad odour.

VERMICOMPOST

Vermicompost is the excreta of the earthworms, on digesting the organic wastes. Vermicompost brownish or blackish in colour, and is odourless and granular in texture. Earth worms feed on agricultural waste, castor and groundnut residues, coir dust, sugar cane bagasse , household wastes vegetable market wastes, poultry wastes etc. These organic wastes are passed through the digestive system of earth worms and come out as excreta compost. The humous contain a high percentage of humic and folic acids that facilitate immediate availability of nutrients of plants. Vermicompost improves the texture and composition of soil. It also acts as a biological insecticide thereby controlling the harmful soil pathogens and insects. Its application will improve the water retention capacity and aeration of the soil, besides biodynamic action which increases the organic functions of plants.

It view of these advantages the benefits o the plant with the application of vermicompost in addition to avoiding ill effects due to application of chemical fertilizers, it is our responsibility to encourage the usage of compost in our plantations. Therefore, the Regional Manager and the General Manager are advised to establish one vermicompost unit in each center / Range. A brief account on vermicompost is detailed below :

( A ) EARTHWORMS :

Earthworms are classified into 2 categories : ( 1 ) Manuring Worms ( 2 ) Soil Procuring Worms. Manuring worms are 2 types – classified as endogenic and epigenic. The endogenic species are burrowing type and the epegenic species are non burrowing type. It is onlu the non burrowing earthworms that are useful for Vermicompost production.

( a ) Eudrilus eugeniae : This earthworms, an African species and bigger in size measuring 8” to 12” It is red or violet in color. It is voracious eater.

( b ) Eisenia foetida : A European species are measuring 2” to 5” in size. It is also are or violet in color.

Both these species are useful in Vermicompost production in these areas.These earthworms can feed on 100% organic wastes without soil. Lifespan is 2 to 3 years. One earthworms can produce 200 to 300 earthworms in a year. Earthworms through hermaphrodite, self fertilization does not occur generally. It lays cocoons, which consists of 8 to 20 eggs but only a few are fertile which give rise to juveniles ( Baby Earthworms). For a cocoon to hatch, grow and in turn to procduce, it take 60 days.

( B ) Technology of Production

(i) Components for vermicompost Production :

(a) Non-borrowing type earthworms ( 1000 Nos. for each Sqm. Of bed)

(Eddrilus eugeniane, eisenis foetida )

(b) A shed with thatched for tar sheet roofing wit h15’ height at center and 6’ at eves. This is essential to protect the earthworms from Sunlight, rain etc.

(c) One-foot height floor above the ground level to prevent entry of water and slip away of earthworm into the soil.

(d) The size of the bed is L X 2-3 ft W X 2ft ht. Preferably brick masonry work is required. If the height of the bed is more than 2ft, aeration is poor to the earthworms resulting in low production. Width of the bed will be 2-3 ft so that it will be easy to work. The length depends on the length of the shed.

(e) Fencing in all the sides of the shed ( with thorny material ) to prevent entry of pigs, cattle, birds, frogs etc.

(f) Jute bags for spreading on the top of bed to prevent evaporation of moisture and to protect from predators.

(g) 2-3 mm size for collection of Vermicompost.

(h) Fresh cattle dung to start the process of decomposition.

(i) Lime water for controlling the throat infection of earthworms.

(j) Bone ash for better reproduction of the earthworms. 2-3 mm size for collection of Vermicompost.

(k) Fresh cattle dung to start the process of decomposition.

(l) Lime water for controlling the throat infection of earthworms.

(m) Bone ash for better reproduction of the earthworms.

( ii ) Pre-treatment of the organic wastes :

The organic wastes such as sugarcane bagasse, and cow-dung generate heat if applied fresh. Hence, they should be cooled outside the beds on a solid platform by turning frequently while spraying water. This will result in a good quality feed material. The earthworms may die because of excessive heat generated in the process of decomposition. Add 100 to 150 grams of lime and 1 kg of bone meal per ton of the organic wastes outside the bed.

( iii ) Filling the beds :

(1) Sprinkle water on the floor of the bed before filling the pits.

(2) Form 3” thick bottom layer bed with coconut fiber and pack it by profuse watering.

(3) Form 2” to 3” second layer with cow dung sludge. This layer will be immediately useful as the feeding material to the earthworms. This is also called starter dose.

(4) Then, release one kg of earthworms for each 3 Sqm. On the second layer and spread evenly on the bed. Care should be taken that the earthworm is not damaged.

(5) On the top of the second layer form 12” to 14” thick organic wastes with green and dry leaf, kitchen wastes, animal wastes, cow dung etc. Partly decomposed Farm Yard Manure can also be used. Care should be taken that the organic waste do not contain the glass pieces, plastic, vinegar, soaps etc.

(6) Sprinkle the solution made up of cow-dung, done power and small quantity of lime powder on the top of activate the earthworms.

(7) Cover the bed with gunny bags during the day time to provide dark atmosphere and remove it in the night time for better aeration.

(8) Spray water with rose cans two times a day at 9.00 am and 5 pm Earthworms are most comfortable in humid and dark atmosphere and below 35* C. Care should be taken during summer season to maintain temperature and humidity by spraying water and covering the side of the shed with gunny bags or Bamboo mats.

Once the total feed material is eaten away, the earthworms come on top of the bed at attach themselves underneath the gunny bags. At this stage, stop watering for 2 days. Earthworms will go to bottom layer ( moisture zone ). Now heap the entire bed material in small quantities. Sieve the collected material to separate Vermicompost from earthworms. Keep the surroundings always free from ants and redents.

( iv ) Rate of Production of Vermicompost is directly proportional to number of earthworms reproduce more, production will become faster from the beds. Earthworms reproduce prolifically in humid and low temperature. The production output is generally 60%.
