Step one: Bananas are considered a staple at our breakfast table. Cut the banana peels that accumulate each day into small pieces with scissors or a knife. And store in a container with a lid. Doing this will benefit you a lot. Because it will save time, chopping many peels at once is time-consuming and pieces will dry well very quickly.

Step two: When the container is full, keep it for 2 to 3 days and dry it well in the sun. Check if the pieces of peel are cracked. If not, soak it in more sunlight. You can use a microwave oven to do this if you want. In that case, the microwave should be kept on low heat.

Step three: Grind dry banana peels well with the help of a grinding machine or iron pestle set. And start the practical preparation phase.

Dosage: You can apply one to two tablespoons of this fertilizer once a month as per your plant. And before application loosen the soil around the base of the plant and spread the fertilizer and mix it with the soil. And wet the soil by spraying water. You can use this fertilizer when making mixed fertilizer for a good result. If the use of this organic fertilizer is less or more, there is no effect on the plants. It can be used for new soil-making purposes.

Method two: liquid banana peels fertilizer

There are other methods of making fertilizer from banana peel. If you are interested in applying liquid fertilizer, follow this procedure.

Step one: Take small pieces of dry or fresh banana peel and put them in a jar of about 50 to 60 per cent.

Step two: Fill the rest of the jar with water and close the lid.

Step three: Place the jar in a shady spot for at least a week. And be sure to shake the jar lightly from time to time.

Step four: After a week, separate the soaked peel pieces from the liquid extract using a strainer from the jar. Your banana peel liquid fertilizer is ready to use.

Remaining the old peel pieces can be mixed with new pieces to make re-liquid manure. Or you can compost it by mixing it with soil.

I do not follow this method. Because using this method is prepared the liquid fertilizer, the entire nutrients of the banana peel are not dissolved in the water, especially the fresh banana peels. As a result, the plant is deprived of the complete nutrients of this fertilizer.

If you want, you can prepare this liquid fertilizer by using powdered fertilizer instead of banana peel pieces as per the method mentioned earlier.

According to myOpptone:   

the best method is to prepare liquid fertilizer with powdered banana peel fertilizer. Because powdered banana peels are dissolved in the water properly, and they decompose better with water. And apart from potassium, all the other nutrient particles are dissolved in water to form a completely nutrient-rich liquid fertilizer. Which helps to give a better output to your plants.

Dose: Apply the liquid fertilizer by mixing 1:5 with water.  If you take 1 cup of banana peels liquid fertilizer and mix well with 5 cups of water.

Now use the fertilizer at the base of your plant. And wait a week or two to start seeing the amazing results.

Strain this liquid fertilizer using filter paper. And you can mix well the liquid with water in a ratio of 1/5 and take the liquid in a spray bottle and spray it on the leaves and branches of your plant, it will give good results and thereby prevent feeds.

  Note: If there is a bad smell, then you should not use liquid fertilizers on your plants.

Method three: liquid banana peels fertilizer mixed with bone meal powder or eggshell powder & Epsom

To make this peel liquid extract even better, make a solution of steam bone meal powder or eggshell powder mixed with Epsom salts and spray on plants for better results. Read below to know the preparation method.

Step one: Take two tablespoons of steamed fine bone powder or eggshell powder in 250ml of banana peel liquid extract in a container. And keep it covered in a container for 1 to 2 days.

Step two: After 1 to 2 days add one tablespoon of Epsom salt to 1 litre of water. and mix well.

Step three: Strain 250ml of banana peel or bone powder mixed solution in 1 litre of Epsom salt water and mix well.

Step four: Take the mixture in a spray bottle and spray it on your plants.

Many take a simpler approach to provide plant nutrients. Banana peels are spread over the soil around the base of the plant. Although this method can meet the plant’s potassium requirement to some extent, but in this process, the plant is deprived of complete macro and micronutrients.

Because, when whole banana peels will use as fertilizer for your plants, it can take up to one and a half to two years for them to completely break down or decompose in the soil and leading to fungal infections.

If you any hesitant to make fertilizer from the banana peels. So, there is another very easy way to get these banana peel benefits. Grind the fresh banana peels with the help of a blender and mix them with the pile of soil used for the plants. Soil helps faster decompose the Ground banana peel. The maturity period of mature banana peel compost is 75 to 90 days. And after the day you can use the soil for new plant planting and repotting the plant in the pot.

Banana peel fertilizer NPK:

NPK values are 0.6-0.4-11.5 on a per kg weight basis of dry banana peel. NPK value of fresh banana peel is 0.1-0.1-2.3. Which is 5/1 part of dry banana peel.

Benefits of banana peel fertilizer:

Banana peel is a source of the main sources of organic potassium. It contains up to 3.42 mg/100g of potassium. Apart from this, banana peel is rich in micro and macronutrients (as per DW) like nitrogen (0.054mg/100g), manganese (0.01 mg/100g), phosphorus(1.63mg/100g), magnesium(0.95mg/100g), calcium(2.50mg/100g), sulphur (1.3mg/100g), iron (0.01mg/100g), sodium (24.30mg/100g), molybdenum(0.1mg/100g), copper and zinc(0.01mg/100g) both.

Potassium: Banana peel fertilizer is a major source of potassium. This potassium helps move water and nutrients between cells. Helps improve flower and fruit quality. Helps to give plant stem strength and growth. Also helps prevent disease. Makes plants drought resistant.

 Calcium: The calcium present in banana peels is great for adding oxygen to the soil and accelerating plant root growth. And also helps plants take up more nitrogen.

Magnesium: Magnesium plays an important role in the formation of chlorophyll, the main component of photosynthesis.

Iron: Iron is an essential element for plant photosynthesis and chlorophyll formation. which does protect against the chlorosis of your plants. 

Sulphur: Helps plants form chlorophyll, develop roots, and protect against pests.

Phosphorus: Helps in enhancing the efficiency of pollination and seed germination. Helps improve fruit and flower quality. Helps strengthen plant stems and roots.

Sodium: Helps move water and iron between cells.

Manganese: Plays a special role in plant photosynthesis.

Molybdenum: Molybdenum is an essential nutrient for healthy plant growth.

Copper: Copper is one of the essential micronutrients in plants. Which is required for many enzymatic activities in plant chlorophyll and seed production.

Zinc: Zinc is an important element in a number of enzymes responsible for driving metabolic reactions in all crops. Without certain enzymes in the plant tissues, growth and development stop and the formation of chlorophyll is significantly reduced.
