What is Waste Decomposer?
Waste decomposer is a bio-fertilizer, bio-pesticide, bio-control and soil health reviver developed in National Centre Of Organic Farming, Ghaziabad (India) by Dr. Krishan Chandra. It is basically a consortium of few beneficial microorganisms produced from Indian cow dung.
These microorganisms produces primary metabolites that are a precursor of anti microbial compounds. It also produces anti microbial secondary metabolites including polyketides and alkanes.
These antibacterial microbes in the farm soil and plants controls and prevents diseases. They also produces glucanase and β-1, 3 glucanase enzymes that helps to improve defence mechanisms of the plants.
Waste decomposer acts as quick decomposer of waste compounds in the soil and has been prepared from cow dung by Dr. Krishan Chandra.
This amazing multipurpose bio-fertilizer can be used in large scale agricultural farms as well as in home garden. The process to prepare this manure is very easy, cost effective and take only 5 days to be prepared.
It costs only 20 Rupees to buy a bottle of waste decomposer. The shelf life of this manure is three years. Once you have prepared the solution of microbes in your farm or home garden then you can use the same solution to make more manure again and again.
Farmers or garden enthusiast doesn’t need to depend on costly fertilizers or pesticides after using this manure. It does all work for your plants. I will suggest all my readers to use this once and observe its benefits.

How to prepare solution of waste decomposer?
Waste decomposer is the basic material required for preparing a mass multiplication solution of useful microbes. In this article I will discuss both techniques of preparation for large scale farm lands as well as for urban gardens in cities.
In large scale farms you can prepare mass multiplication solution in a 200 litres plastic drum. Only use plastic drum for this purpose. Avoid using any metallic material in the whole process.
You can buy waste decomposer pack from here: Purchase Waste Decomposer
Materials required are:
- Plastic Drum (200 litres capacity)
- Jaggery (2 Kg)
- Waste Decomposer (one bottle)
- Water
Process
- Fill the plastic drum with 200 litres of water and mix 2 Kg Jaggery in water with the help of a wooden stick.
- Empty a bottle of waste decomposer in the water drum and stir the mixture very well with the help of a wooden stick.
- Cover the drum properly with plastic or wooden material. For 5 days you have to open the covering only when you will stir the culture.
- Stir the culture twice in a day for 5 minutes with the help of a wooden stick.
- After 5 days the solution will turn creamy. After 7 days you can use this solution mixed with water in 1:3 to spray in your farm.
Once you have formed this solution you can use it again and again to make more solutions. To make more solution save 20 litres of prepared solution and mix it with 2 Kg jaggery in 200 litres water in the same plastic drum.
After 7 days this solution will become ready to be used. You can repeat this process to make more and more solutions to use in your farm and save lots of money that you are spending on fertilizers and pesticides.

Yes, it is going to affect your land if the distance between two farms, one being organic and the other inorganic is less than 50 feet.
I stir the wdc solution twice a day as instructed and is properly covered too but then too there are white worms in the solution.
Strain the solution and reuse it, generally due to the rainy season, the worm population increase exponentially.
dear Sir
can you please mention what are the bacteria types including in this ” waste decomposer”
this is for my knowledge. Because i am confused with “BOKASHI” solution which is also use
decompose kitchen waste.
please clear me…
Hi,
It contains Bacillus sp., Corynebacterium sp., Lactobacillus sp., few fungal sp., (Aspergillus and Trichoderma).
dear sir
thank you for the reply and can you tell me what difference with
“Bokashi preparation” with WDC.?
Because i applied “bokashi preparation” on to pre composting process before introduced to
worm’s bed. After 3 weeks later i put half composted materials to my worm’s bed. Finally, i noticed worms’ population reduced. But when i used WDC for pre-composting process and applied to wormy bed after 3 weeks worm population increased gradually without any hassle. can you explain it to me sir what is the possibility to happen like this since Lactobacillus is available in both solutions.
