Compost or Vermicomposting is a type of manure that provides critical nutrients to the soil. In simple terms, manure contains a lot of organic matter and provides the soil with a few nutrients. Manure is created when animal excrement and plant waste decompose. Manure adds nutrients and organic elements to the soil, improving its fertility. The majority of the organic matter in manure helps to improve soil structure. This requires increasing the water-holding capacity of sandy soils.

Large levels of organic matter help drainage and prevent waterlogging in clayey soils. Manure is made from biological waste, which helps the environment by lowering the demand for fertilizers. Another way to recycle farm waste is to use biological waste.

Depending upon the type of Biological material used it can further classified into two different types:

• Compost or Vermicompost
• Green Manure

Compost

There are a lot of organic components and nutrients in the compost. It is made from farm waste such as cow dung, animal waste, vegetable trash, domestic garbage, weeds that have been eliminated, sewage waste, straw, and so on.

Composting is the process of decomposing trash in pits and turning it into compost. Composting is accomplished through the biodegradation of garbage and the addition of organic matter.

Microbes, namely Thermophilic bacteria, break down the waste products. Yeast is also useful in the composting process. The soil is suitable for plantation and farming because the compost is rich in minerals and micronutrients.

In a compost pit, these earthworms can be found. Moisture, warm climatic conditions, and easily available compost material are ideal for these earthworms. Vermicompost is created when earthworms consume compost material. 

Mechanism of Digestion in Earthworms

• In worms, food is consumed through the buccal cavity, which emerges during eating and is aided by protractile and retractile muscle. The food is swallowed through the pharynx.
• The chromophil cell in the pharyngeal gland is where saliva is formed. Mucin softens food, and protease turns protein to amino acids, both of which are found in saliva.
• The gizzard is the next region through which the food passes (oesophagus). By contracting the gizzard muscle, the food particles are transformed into fine compounds.
• Many digestive enzymes, such as protease, amylase, cellulase, chitinase, and lipase, aid in the breakdown of various nutrients.
• Worm casting, or vermicast, is the term for the substance they discharge. It contains a variety of minerals that plants can easily utilize.

Vermicomposting

Organic wastes are used to make vermicomposting. Compost is made utilizing worms such as earthworms, white worms, red wigglers, and others in a natural and ecological process. Earthworms decompose organic waste into manure, which is high in nutrients and utilized for bio fertilizers, organic farming, and sewage treatment. Vermicomposting is the term for this procedure. Vermicomposting differs from composting in that it is created through the decomposition of organic matter.

Process of Vermicomposting

Vermicomposting requires the cultivation of earthworms. The capture of earthworms, the construction of a compost pit or bed, the harvesting of compost, packaging, and marketing are all part of the vermicomposting process. 

Collection of Earthworms

Earthworm multiplication is a crucial phase in the vermiculture process. Farmers can simply accomplish this by following the procedures outlined below:

• Different sorts of biodegradable wastes, should be added.
• After thoroughly combining all ingredients, approximately 40 or more kinds of earthworms are added to the mixture.
• A monthly maintenance check is required to protect the mixture from heat, rain, and other environmental factors.
• Throughout the interval, the temperature and moisture level must be maintained.
• When kept in good condition, earthworms can multiply 300 times in two months.

Construction of a Vermicomposting Unit

• The process of vermicomposting is carried on once the earthworms are ready to change ordinary soil into a treasure of nutrients. The steps in the procedure are as follows:
• The initial stage in the process is to build a vermicomposting unit, such as a compost pit or a vermibed.
• Various wastes, as well as earthworms, are layered one on top of the other in this step. The pit is covered with either coconut leaves or old gunny sacks to keep it safe.
• To accelerate decomposition, the chemicals are turned upside down after a particular number of days.
• Worm tea is the worm liquid found at the bottom of the compost pit. It is extremely beneficial to the growth of garden plants.

Harvesting of Vermicompost

• Worm casting production indicates that vermicomposting is ready for harvesting.
• Worms are separated from solid garbage at this stage using light treatment or sieves or meshes.

Packaging, Transport and Marketing

The isolated product is packaged in laminated over sacs to prevent moisture loss and labelled with information such as the brand name, nutritional data, directions for use, price, and other details before being shipped to farms, gardens, plant nurseries, and greenhouse plants, among other places.

Advantages of Vermicomposting

• Chemical fertilizers are best replaced with vermicomposting.
• Vermicompost is environmentally friendly because it is made from organic waste through vermiculture.
• Vermicompost is a natural fertilizer, as well.
• The organic components utilized in vermicomposting boost the water retention capacity.
• Plant growth and nutrient absorption capability are improved.

Disadvantage of Vermicomposting

• Vermicomposting takes a lengthy time, about six months.
• It has a little odour to it.
• The cost of maintenance is high since it must be maintained for an extended length of time.
• There is a risk of infections and pest problems if not properly cared for.
• It’s a lengthy procedure.
