Let's make a good use of coffee grounds to make fertilizer. Many people would like to use coffee grounds for soil improvement if they can easily make useful use of the grounds that would otherwise be thrown away. For organic farmers who are particular about their fertilizers, we recommend making fertilizers from reused coffee grounds because they are environmentally friendly.
Coffee grounds as they are cannot be used as fertilizer.
The use of coffee grounds as a fertilizer is explained in detail below, but coffee grounds as they are are not suitable for use as a fertilizer. The method for using coffee grounds as a soil conditioner as a fertilizer, which are usually left over and thrown away, is a simple method that anyone can do, although it takes some time.
In this article, we will explain the good and bad points of coffee bean fertilizer, how to make it, and how long it takes to make it.
What you need to know about fertilizers before making coffee bean fertilizer
Types of fertilizers are chemical fertilizers and organic fertilizers

There are various types of fertilizers, which can be broadly classified into chemical fertilizers and organic fertilizers. Chemical compound fertilizers are made by using chemical substances to add the necessary nutrients of tisso, potassium, and phosphorus to the soil in a well-balanced manner. The major difference between chemical compound fertilizers and organic fertilizers, which are made from living organisms, is said to be their environmentally friendly soil improvement effect.
Coffee grounds fertilizer is an organic fertilizer
In addition to artificial chemical fertilizers, organic fertilizers can be made from coffee beans, and are called such because they are made from organic matter (animals and plants) found in nature.
Compared to chemical fertilizers, the balance of nutrients in organic fertilizers varies depending on the raw materials used, but the advantages are that they can be made at home by mixing food scraps and rice bran that would otherwise be discarded at home and fermenting them, and that they can be made soft and fluffy by working with the microorganisms in the soil.
Reasons why coffee grounds can and cannot be used as fertilizer
Reasons why coffee grounds cannot be used as-is as fertilizer
Reason 1: Nitrogen starvation

Coffee grounds contain some nitrogen. If used as is, on the contrary, the nitrogen content in the soil will decrease and plants will become deficient in fertilizer (nitrogen starvation).
Quote from: https://www.pref.kanagawa.jp
Reference: Kanagawa Prefecture Website Agricultural Technology Center|Agricultural Use of Coffee Lees|
It is said that coffee grounds, which are organic matter, can be used as fertilizer, but it is known that using coffee grounds as is as a fertilizer is not good for plants. This is because the chitoso component in coffee grounds reacts with the soil, causing a lack of nutrients.
Reason 2: Growth Inhibiting Components
Another reason why coffee grounds as is are not suitable for use as fertilizer is because of the growth-inhibiting components that are said to be contained in coffee grounds. It would be a problem if the intention is to use coffee grounds as fertilizer, but instead they interfere with the plant's ability to grow.
When using used coffee grounds as fertilizer, it is recommended to use them as fermented compost.

Reasons to use coffee grounds as fertilizer 1.
Coffee grounds are not visible to the naked eye, but they have many holes in them that help activate microorganisms in the soil. Coffee grounds as they are cannot be used as fertilizer unless they are decomposed into organic matter containing carbon, but you just need to wait until the decomposition process is complete.
As long as time passes, good quality compost can be made, so even beginners will be able to make safe fertilizer easily and without difficulty.
Reason 2. Deodorizing effect of compost
This is another way to utilize the porous nature of coffee beans. The large surface area of coffee beans has a great ability to absorb odors, and coffee grounds can be used as a deodorant by reducing the foul smells unique to compost.
Although it has nothing to do with the effect of the fertilizer on the soil itself, if the smell of the compost is a reason for not using organic fertilizers, compost fertilizers using coffee grounds are highly recommended because of their low odor.
How to make coffee grounds fertilizer
You have learned from the previous section that coffee grounds should be composted, not used as a fertilizer. Now, let us introduce how to make compost that can be used as a fertilizer for plants.

There are a few things you will need to prepare for composting. There is no single way to make compost, so you do not necessarily have to follow this method, but even beginners should try it as a way to make coffee grounds fertilizer as easily as possible with as few materials as possible.
What to prepare for making coffee grounds fertilizer
You will need a small cardboard box about the size of a small oranges and a towel or old T-shirt to cover it. Coffee grounds should be dried in the sun, not immediately after use.
If you have a lot of fallen leaves, use them; if not, use commercially available humus. This will be the base for making compost. Rice bran is also recommended for adjusting the water content as it may come out during fermentation.

Coffee grounds fertilizer container is a cardboard box.
Cardboard is the container for making coffee grounds fertilizer. Breathable paper containers are recommended over plastic buckets. This is because organic fertilizers are alive and need to be allowed to breathe.
If it is not possible to use a double layer, it is recommended to spread newspaper on the bottom to reinforce the bottom for 2-3 days to prevent moisture from the compost before use.
How to make coffee grounds fertilizer 3. Mixing

The maximum ratio of coffee grounds to fallen leaves or leaf litter is 80% to 20%. Less than this is fine. Coffee grounds can be dried and added to the mixture every day, so it is best to start with a higher ratio of humus to coffee grounds to avoid mistakes.
Mix the coffee grounds and fallen leaves or humus well, cover with a cardboard lid, cover with an old cloth to prevent rainwater from getting inside, and fasten with string.
Let the compost breathe and be careful of moisture.
Most people will place the cardboard outside. This is because it will ferment and will smell. Good ventilation is also important, as the box will collapse over time if placed on the ground as it is. In addition, please choose a location that has a roof over the box and is not directly exposed to rain.
Also, do not use plastic sheets or other non-breathable materials to cover the box, no matter how much rainwater is allowed to get in. Use a cloth material such as a towel or T-shirt that will allow the compost to breathe.

Coffee grounds compost is left to ferment and mature for at least one month before it is ready. During this process, the contents of the compost will heat up, which is a sign that it is fermenting. If the compost is not warm or watery after several days, add 1-2 tablespoons of rice bran and stir well.
If the compost does not heat up and is too dry, add a little water, stir and see how it goes. Be careful not to add too much water.

If you produce coffee grounds every day, you can add more each time after they are thoroughly dried. Instead, it is recommended to note the date of addition, as you want to wait one month after the last addition of coffee grounds before you can use them as fertilizer.
Always stir the compost fertilizer well every day, whether you add coffee grounds or not. It is the same as not stirring a bed of bran every day. The trick is to stir the whole mixture to let it air dry.
How to use coffee bean fertilizer
Mix in bitter lime.

Coffee beans have acidic properties. This remains even after composting, so it is best to use a slightly larger amount of bitter lime when using it as fertilizer in the field. If your plants prefer acidic soil, you can use it as it is.
Tips for use 2. Mixing with soil
Organic fertilizers such as compost are good because they improve the soil by working on the microorganisms in the soil. When using organic fertilizers, it is better to mix them with the soil rather than spreading them on top of the soil.

The last point is not a usage tip, but unlike chemical fertilizers, organic fertilizers such as compost are said to be less effective immediately. Even if you do not see a big effect immediately, it is good for the soil to create an environment where microorganisms can feed and increase, so please continue to use it.
Summary: Reuse coffee grounds as fertilizer

Can coffee grounds be used as fertilizer?
Coffee grounds cannot be used as fertilizer in their original state.
Coffee grounds are literally "dregs" with the nutrients extracted from the coffee bean.
If coffee beans are mixed with soil for growing plants in this state, the amount of nitrogen in the soil will be reduced, which could have a negative impact.
However, coffee beans are porous, with many pores, and they can be used as a humectant, a fertilizer, and to alleviate the characteristic odor of coffee beans.
By mixing coffee grounds and fertilizer and allowing them to mature, they promote the growth of microorganisms and make the soil in good condition.
You can make it at home! How to make fertilizer with coffee grounds
There is a method using rice bran to make fertilizer from coffee grounds, but this time we will explain how to make a simple "coffee grounds fertilizer" using only humus.
Also, it takes one to three months to complete the process, so patience is required.
Necessary Items and Preparation
Coffee grounds (about 500 g)
Cardboard (thicker is ideal)
Newspaper
Leaf mold (1.2 L)
Shovel or gloves
This time, cardboard will be used as a container for making fertilizer.
If you are unable to prepare a container, a bucket or other container that can get dirty can be substituted.
Also, since you will be stirring the fertilizer every day until it is completed, it is safe to prepare a shovel or gardening gloves in advance.

What you need to do as a preparation is to dry coffee grounds.
Wet coffee grounds can cause mold.
Make sure to dry them before making coffee grounds.
About 500 g dried coffee grounds
Make containers out of cardboard
Cardboard is used as a container for making fertilizer with coffee grounds and humus.
After returning it to its box state, seal the bottom tightly with tape.
Inside, spread a large sheet of newspaper for about one day to prevent the humus and coffee grounds from leaking.
Mix dry coffee grounds and humus
Put the humus and coffee grounds into the box made above in this order: humus first, then coffee grounds.
As explained above, coffee grounds can cause mold growth, so use coffee grounds that have been thoroughly dried in the preparation.
Wet is not acceptable.
After putting them in, put on a prepared shovel or gloves and stir them around evenly.
If the storage place is outside or on a balcony, cover the cardboard box with a towel to avoid rain, wind, and insects.
In my case, I used bricks to raise the bottom.
That's all for the first time, but make sure that the storage area is well ventilated.
Make sure to raise the bottom of the box and store it in a well-ventilated condition so that the air can spread to the bottom of the cardboard as well.
Stir daily
Stir the soil daily to speed up the fermentation of soil and microorganisms.
The key is to keep it in a well-ventilated place and stir it daily to aerate the soil.
If you have more coffee grounds during this time, you can add more.
This process will encourage the microorganisms in the soil to decompose and ferment, resulting in a good quality fertilizer.
When the soil becomes slightly hot after about a month, it is a sign of maturity. You can use it as a fertilizer!
Is it OK to spread it in the garden as is?
No. Coffee grounds must be fermented or they will contain caffeine.
Caffeine is a substance that inhibits the germination and growth of plants, so it is absolutely not acceptable to sprinkle coffee grounds as is in areas where plants are being grown.
On the other hand, if coffee grounds are sprinkled in areas where weeds are not wanted to grow, it will prevent weeds from growing.
If you feel that the above process is too much work for you, you can reuse coffee grounds in ways other than as fertilizer.
Summary of using coffee grounds as fertilizer
Coffee grounds can be easily made into fertilizer if they are dried.
However, it takes time to ferment, so patience is required.
If you want to reuse coffee grounds easily, sprinkling them in areas where you want to control weeds is effective!
