Benefits of using cow dung cakes

Cow dung contains three prime nutrients that plants require and that’s the biggest benefit of using it for plant growth. Read more about the benefits of using cow dung cakes for plants below: -

  1. Cow dung has about 3% nitrogen content. Nitrogen is a prime component in chlorophyll, and without that, plants cannot make their food. It is also a crucial part of amino acids, which serve as the building blocks of proteins. Plants deteriorate and perish without proteins.
  2. One of the key plant nutrients, phosphorus, is present in cow dung at a rate of 2%. It is a component of plant cells and necessary for cell division and the growth of the plant's growing tip.
  3. 1% of the potassium in cow dung aids in controlling the stomata's opening and shutting, which controls the exchange of water vapor, oxygen, and carbon dioxide. Produce suffers and plant growth is impeded when there is a potassium deficiency.
  4. It is reasonable and cheaper to use cow dung cakes to reduce soil deterioration brought on by excessive chemical fertilizers, which can change the bacterial diversity and community structure of soils
  5. The soil's ability to retain moisture is increased when cow dung cakes are mixed with soil
  6. You don't need to water your plant as frequently because soils can hold more moisture after you feed it with cow dung cakes
  7. With cow dung cakes, the aeration also improves, which helps break up compacted soils.

How to make cow dung cakes?

  1. First of all, you have to gather all of the excrement in one location. For improved processing, you must collect the feces for several days
  2. The second step is mixing cow dung with water. Put on gloves and a mask for your hygiene. Avoid making it excessively thin or thick.
  3. The third step is to make flat cakes. A thin and flat shape is much preferred because it will dry faster and would be better for carrying purposes later.
  4. These cow dung cakes are dried on the walls of houses in rural India. To dry these cakes, use the side of your home that gets the most sunlight. Typically, it takes 3-5 days for everything to dry completely.
  5. Now put them away somewhere dry so you can use them later as fertilizer or as cooking fuel.

How to use cow dung cakes on plants?

Common method: -

  • 1 cake should be soaked in 2.5 litres of water for 2 to 3 days
  • The cake should be broken up and combined with water
  • Feed the plant with 300 ml of the solution once every week
  • Up to five litres of water can be used with a set of two cakes
  • Make sure the soil has appropriate moisture before adding the solution to each pot

Fresh cow dung

Fresh cow dung should be avoided for direct application to plants because, first of all, it has a foul smell, and secondly, plants could be burned by the high concentration of salts and nitrogen present in the dung. It also includes harmful microorganisms like E. coli, that are toxic to both plants and people. Additionally, it includes weed seeds, which might result in an abundance of weeds or undesirable plants in your garden.

Aged cow dung

The more the cow dung ages, the better it gets. For that you can dig a hole in your garden and collect cow dung for several months. Cover it with your garden soil and let it age for at least 6 months. After that collect soil from here and use it as a fertilizer for your plants.

Dehydrated cow dung cakes

The one mentioned above in "how to make cow dung cakes" is dehydrated cow dung cake. Dehydration simply means a lack of water. After preparing the cake, you leave it to dry for 3–5 days, during which time the water content is absorbed and the cake is ready for use. Through this procedure, the amount of salt, ammonia, and dangerous bacteria is somewhat decreased.

Composted cow dung

The greatest and safest organic fertilizer for your plants is produced when you add cow dung to the composting process. Composting cow dung has a number of advantages, like reducing dangerous ammonia levels, eradicating weed seeds already present in the soil, and enhancing soil drainage, aeration, and moisture retention. This kind of cow dung is the safest and best choice for plants and can be put once a month on the top soil after raking or tilling the soil, or it can be mixed with potting soil in a 20 to 30% proportion.

Other uses of cow dung

Fuel and bio gas

The cow dung cakes are very good as fuel. People in rural areas manufacture their own cow dung cakes to use as fuel for cooking. Methane makes up 55% of the biogas, along with carbon dioxide (30%) and other gases including nitrogen and hydrogen. The entire collection of cow manure is used as feedstock to create biogas. It results from the anaerobic breakdown of cow dung. Cow manure may easily be converted into biogas. Certainly, using recycled cow dung expands the possibilities for creating a greener environment.

Heating purposes

In colder regions, cow dung cakes can be used in fire places that will keep the room warm.
