Over the past few decades, the use of food and insect-killing poisons in agriculture sector has increased greatly. Which has led to a huge increase in our per hectare production, but there are many negative effects that have also been felt in our lives. According to a study, only 25 percent of the fertilizers given to crops are used by plant waste decomposers, while the rest either flows with water or fixed in the earth in another form. This part of the lost nutrients is also causing many changes in our environment. The use of heavy metals in the plants, the worsening of the natural environment, water borne problems, changes in the soil properties, and also many diseases in humans. To avoid this, many agricultural experts recommend the use of organic foods, also known as organic farming in common language.Waste decomposer is a technology by which not only we can get rid of chemical foods and poisonous sprays in a short time, but also makes the soil soft and rich in nutrients. This also increases the amount of organic matter in the earth. Which can lead to the cultivation of organic crops. Most of the chemical foods. Similarly, if organic matter like cow dung is applied to the soil, its decomposition is very slow, due to which nutrients availability to crops is delayed.

We buy poison in the form of agricultural sprays, crops, even milk from our money. We do this but we don’t want to, because there was no alternative.

Waste decomposer contain bacteria that produces such organic acids that are a very quick. They decompose organic matter and made nutrients available to crops in no time.

Waste decomposer are used to grow organic foods, bio control and to increase land production capacity.


There are many uses of waste decomposers some of them are described below:

  • Using it can change the nature of the soil in a short time
  • This can make all types of wastes into organic fertilizers by de-composing in a short time
  • This can form organic sprays against insect pests and diseases
  • Micro-nutrients sprays can be made from waste decomposition.

How to make waste decomposer?

Waste decomposer was introduced by National Institute for Organic Farming in 2015.  This is a collection of microbes obtained from native cow dung. The procedure for creating it is as follows:

Take a 200-liter drum and fill it with water. Take 2 kg of jaggery (Gur) in a separate bucket and made a homogeneous solution. After that add this solution into the water drum. 

Take the waste decomposer mother culture from a trustworthy source for first time.

Add the mother culture in sweet solution of water an d mix it well. Put the drum under shade and cover the top with a cloth or jute sack or cover. Open the drum and shake it well on daily basis. In seven days, when the water color changes and foam starts to appear on top with pungent smell, then you should know that your culture is ready.

Fill a bottle with a ready-made culture so that it can be used as mother culture in next phase later. Use the rest to prepare fertilizer or spray. Also, this can be mixed with irrigation water while irrigating the crops.

For first time use, apply the 1000-liter for one acre and you will see significant difference in few days. The soil will start to become very soft, rich and fertile. 

A cemented tank can be made in the shade near field irrigation bodies in which grass, kitchen waste, crop residues, gur, molasses, cow dung and other organic wastes can be added with mother culture of waste decomposer for seven days. This can then be used for irrigation purpose.

First-time use can reduce the use of chemical fertilizers by up to 25%. And over time, it can be used to minimize the use of chemical fertilizers up to 100 percent. To get completely rid of the chemical fertilizers, the use of organic matter along with the waste decomposer has to be increased. Similarly, chemical fertilizer can be substituted at a pace.
