Seek light ground to throw away.

The troubles of land that urban patios have

The existing weight could not stand it

Since the fall, I have been going back and forth between the house and the home center many times in search of materials while sowing a variety of vegetables. And I feel it is very consistent.


Mamachari is an urban transport vehicle without its own car. If you want to carry your children on the ground to sweat, you just need to carry them home. Furthermore, it is difficult to lift it up even if you move it to a sunny place after planting.

It is not easy to dispose of it

I can’t put soil in the trash …

More worrying is the method of disposal. The soil cannot be put out as garbage. I tried to contact the counters of some local government, but I was introduced to one of their toll collection companies, who said “the land is not garbage and cannot be collected”. It seems that many of Tokyo’s 23 wards are doing the same. It’s hard to buy or throw away land in the city.

However, there are god who throw away. I was anxious and searched online and found that there are many types of land for sale to satisfy the concerns of apartment residents. I picked up Tsukuka quickly and tried to order it.

5 types of soil are light and can be disposed of as trash

Light soil

The first thing I get is “Karui Cultural Land” (Protoleaf).

It came with the “Golden Grain Cultural Land” (Iris Oyama) that I ordered at the same time. First, after taking the gold paddy out of the cardboard, it’s so light that you can’t help but admire this “lightweight soil”. Can be lifted with one hand.

The moment I hold the “light paddy soil”, I realize how light it is.

When I looked up on the official website, 14 liters of gold cultivated soil weighed 8.25 kg, while 12 liters of light ground soil weighed 2.7 kg. When converted to 10 liters, they are 5.89 kg and 2.25 kg, respectively.

The raw materials are “Akatama soil, Kanuma soil, peat moss, leaf soil, bark manure, rice husk manure, husk peat”. When it comes to lightweight cultured soils that can be disposed of, it seems that the main material is palm fiber, but it is characterized by a rich red soil and Kanuma soil that has been used as garden soil since ancient times.

“Karu-i cultured soil” also contains shade soil and Kanuma soil in general cultured soil.


On the other hand, the name “protoleaf” from the same producer claims “100% coconut fiber”. The raw materials are all from the palm tree, such as “coco peat” and “rice husks” which are made by crushing the outer bark of the palm tree. It seems that the product comes from the voices of consumers who think they are having difficulty handling soil.

“Abandoned land” is made from 100% coir

Characteristically, it contains “mycorrhiza”. Mycorrhizal fungi are microorganisms that coexist around the roots and are believed to increase the plant’s ability to absorb nutrients and resist pathogens. It weighs 5 liters and weighs 1.5 kg. This is also very light.

It is said that it contains “mycorrhiza”

Ecoco Soil

“Eco-Cosoil is garden land thrown away as burnable trash” (Planet) is also a product that sings “100% natural ingredients” like coconut shell. The main ingredient is coco peat, which contains soil nutrients made from brown sugar.

“Eco-cosoil” is composed mainly of coco peat and contains soil conditioner.

When I took it out of the bag, I found that the fibrous material was mixed with the colorful granular material. When I asked the agent, it seemed to contain fertilizer. According to the manufacturer, it weighs 14 liters and weighs 4.3 kg.

There is a layer of fertilizer covered inside the fiber

Land for growing flowers and vegetables

It is understandable from the naming of “Land for growing flowers and vegetables can be considered a flammable waste” (natural applied chemistry). It is said that it uses 100% plant material containing compost bark and coir, which is a “natural plant organic matter”.

“Land for growing flowers and vegetables can be discharged as flammable waste” is also claimed to be 100% plant material

Burke compost is an organic fertilizer made by fermenting the bark of the tree, and is one of the soil regulators that make the soil loosen. This is probably the reason why it has a darker color than the brush-only type. There is no mention of weight, but when I roughly measure my balance, it is only 5 kg.

Overall, it is a bit black in color, possibly due to the presence of bark compost.

Vegetable land blooms with water

The lightest and least cumbersome type to take home is “hydrated vegetable land” (Dat Pharmaceutical Company Limited). It is said that these can also be disposed of after use.

There is soil compacted in the box.

The main ingredient is described as “coconut tree” only. Four cubic soils made by compressing coconut palm ingredients are sold in a square box of about 15 cm. Front block water supply 1.4 km. When water is added, it is said that 15 liters will produce approximately 10.4 kg of soil.

I tried to inflate it with water.

It is written that it can be divided into four blocks, but the two blocks in the middle are never broken.

First, take it out of the box and divide it into sections. The explanation says that if you transfer the necessary blocks to the potted plants and pour water over them, they will swell in about 10 minutes. The required amount of water is “6-10 liters per 4 blocks”, so I have prepared 2 liters of water per block.

When it comes to 2 liters of water, the PET bottle is familiar

Place a stopper in the potted plant and pour water over it.

I put it in a potted plant and water it from above, but it doesn’t get absorbed easily

The water in the plate is impervious so I have a bucket ready and have about 1 liter of water available for the time being.

10 minutes after watering

After 10 minutes, the water is not absorbed enough and still lumps. Loosen a little, add water and let for another 30 minutes, finally mix by hand. It is reported that the finished product is 3.7 liters per cubic meter, but it is probably not fully inflated, not enough to fill a 3 liter planter pot.

Amount I put in a 3 liter plant pot

I feel that it doesn’t swell easily, so this time I boil the water in a kettle and sprinkle it with something cold.

Boil the water and let it cool a little before sprinkling

10 minutes after pouring hot water

Then, after 10 minutes, it swelled up significantly. The water is hot, so if you want to use it right away, prepare it with lukewarm water.

I don’t call it “cultured soil”, but it does contain some of the same material as a fertilizer.

“Soil blooming” is not considered a “potting soil” that contains base fertilizer, but if you look closely, it does contain some fertilizer cover. Looks good to add fertilizer as needed while checking for growth status.

* The weight of ④ is approximate weight when the product is measured by weight.
* Weight above 10 liters is guide weight converted from standard weight.

What is your farming capacity?

I picked up 5 lumps of light soil and threw it away.

Similarly, even when coconut is used as the main ingredient, there appears to be differences in properties and functionality depending on the product. I am not sure as it is still used as essential cultured soil, but I am looking forward to future development.

When disposing of soil, even if it is a product marked “discarded”, please check with your local government regulations before disposing of it.

◆ Waste found. But what about planters? So next time I will travel to find a tree planter.
