Summary

  • The humus soil contains many dead and organic substances, bacteria or soil organisms that provide nutrients for the plants. It also stores water.
  • Humus soil can also be used as a nutrient-rich garden soil for soil improvement and landscaping.

The Best Humus Soil: Our Choices

Advisor: Questions you should ask yourself before buying a humus soil

What is humus soil?

Humus soil, often referred to as humus, has the meaning "soil". It is formed by the decomposition of organic matter such as animal and plant remains within the soil. Through the action of oxygen and by means of chemical processes, humus becomes carbon dioxide, water and nitrate.

The darker the soil, the richer its content. (Image source: 123rf.com / 85977040)

Humus soil contains a lot of dead and organic matter that can be found in the top layer of soil. In addition, there are also different types of bacteria or soil organisms that reside within the humus soil.

What is humus soil used for?

Because of its nutrient-rich structure, you can use humus soil alone as potting soil or mix it with other types of soil. Humus soil can be used for plants, vegetables, herbs, lawns or for woody plants. It is also suitable for natural terrarium set-ups.

What is the difference between humus and compost?

The two forms have similarities, but differ in their formation and composition. Soil organisms decompose animal and plant remains and produce a homogeneous substrate that is rich in nutrients.

The humus layer on the soil stores water and provides nutrients for the plants. Unlike humus soil, compost soil does not decompose completely. The heterogeneous substrate is a composition of plant waste.

What does humus soil cost?

The prices of humus soil vary depending on the type of product.

Product type Price range
Humus soil for lawns 7€ - 18€
Humus soil for plants 4€ - 20€
Humus soil for vegetables 7€ - 11€
Humus soil for reptiles 7€ - 15€
Humus soil with cattle manure 1 € - 20€

What are the advantages of humus soil?

The plants absorb the decomposed products as nutrients. With its high nutrient content, humus soil is suitable as a fertiliser. Soils with a low humus content provide very few nutrients to the plants, which can affect their growth over time.

Soils with a high humus content, on the other hand, can store water much better and prevent rainwater from entering deeper soil areas. In addition, humus soil thus also has a protective and insulating effect.

Humus soil also protects the soil from excessive erosion and the plant roots from excessive temperature fluctuations.

What alternatives are there to humus soil?

Besides humus soil, there are many different alternatives that you can use in your garden. The plant soil is suitable for general use and has a higher clay content than the others.

Potting soil is also purely suitable for planting flowers. It has a mixed and humus-rich substrate. Compost soil, bog soil, growing soil, pond soil, orchid substrate and cactus soil are also available.

Decision section: What types of humus soil are available and which is the right one for you?

If you want to buy a humus soil, there are five alternatives to choose from:

  • Humus soil for lawns
  • Humus soil for plants
  • Humus soil for vegetables
  • Humus soil for reptiles
  • Humus soil with cattle manure

In the following paragraphs, we will explain to you what the individual criteria are.

What are the characteristics of a humus soil for lawns and what are its advantages and disadvantages?

Humus soil for lawns is used for repairing or creating new lawns, but also after scarifying or aerating.

Advantages
  • good rewettability
  • good water absorption
Disadvantages
  • fast-germinating weeds

The fine structure provides optimal conditions for germination of lawn seeds and healthy lawn growth.

What distinguishes a humus soil for plants and what are its advantages and disadvantages?

Humus soil for plants provides the plants with a long-lasting and even supply of all important nutrients. It promotes the activity of the soil and thus the formation of roots.

Advantages
  • high humus content
  • stabilises the soil structure
Disadvantages
  • not suitable for sensitive plants

Due to its particularly high humus content, humus soil for plants ensures a sustainable humus enrichment in the soil and thus makes light and heavy soils fertile.

What distinguishes humus soil for vegetables and what are its advantages and disadvantages?

The humus soil for vegetables has organic substances that ensure a healthy development of the vegetables. The organic fertilisers inside ensure the correct supply of nutrients during the first 2-3 weeks.

Advantages
  • Ensures healthy development of vegetables
  • Optimal pH value for vegetables
Disadvantages
  • Only suitable for vegetables

As this humus soil is only suitable for vegetables, it provides an optimal pH value for the vegetables that they need.

What distinguishes a humus soil for reptiles and what are its advantages and disadvantages?

This humus soil is especially suitable for animals with burrowing instincts. It provides an ideal substrate for many arachnids, amphibians, reptiles and many chameleon species that like to dig.

Advantages
  • Ideal for burrowing animals
  • Contains no fertiliser additives
Disadvantages
  • Loses its stability when dried

This special humus soil does not contain any fertiliser additives that are harmful to reptiles. The only disadvantage is that it loses its stability when drying.

What distinguishes humus soil with cattle manure and what are its advantages and disadvantages?

Humus soil with cattle manure is particularly suitable for basic fertilisation of beds and greenhouses, as its high potassium content and balanced nutrient ratio can be used for all plants, vegetables and woody plants.

Advantages
  • long fertilising effect
  • cheaper
Disadvantages
  • bad smell
  • difficult to control nutrient supply

One disadvantage is that many fertilisers limit the nutrients to only one or two. However, the nutrients of organic fertiliser are delivered evenly and taken up evenly by the plants.

Buying criteria: You can compare and evaluate humus soil on the basis of these factors

In the following we would like to show you which factors you can use to compare and evaluate humus soil. In summary, these are:

  • Water reservoir
  • Nutrient storage
  • Peat-free
  • Structure

Water storage

Because of its porosity, humus soil is generally able to absorb water and then store it for a longer period of time than the others. In addition, humus soil can prevent flooding during extreme precipitation.

The humus layer on the soil stores water and thus provides nutrients for the plants .

Nutrient storage

Humus soil contains and stores important nutrients such as nitrogen and phosphorus for plant growth. It holds these nutrients and prevents them from being washed out into the groundwater.

To promote plant growth, it is important that the humus soil has a high content of important nutrients. (Picture source: 123rf.com /118717616)

Peat-free

Such garden, flower or humus soils often consist of 90 percent peat. Instead, peat-free soils contain a mixture of bark humus, wood humus, Chinese reed humus and additives such as lava granulate, clay minerals or sand. These natural ingredients are thus also good for organic farming.

Structure

Metabolic processes of microorganisms and bacteria produce such substances, which are valuable for the growth of plants or vegetables. Above all, humus soil should contain a high content of microorganisms, nitrogen and carbon.

The higher the content of nitrogen and carbon in the humus soil, the more microorganisms it contains.

Facts worth knowing about humus soil

How can you prepare humus soil yourself?

You can buy humus soil either online or in DIY stores everywhere. Humus can also be made in your own garden if you have a composter or areas in your garden that resemble forest soil. You collect kitchen waste in the composter.

Over the course of a year, vegetable peel scraps become humus-rich soil that you can use directly in the garden. The leaves form a natural mull layer, so you can spread it on beds.

Can you mix humus soil?

Of course you can mix nutrient-rich soil yourself and it is relatively simple. When you mix your own soil, you know exactly which ingredients have been used. The right mixture makes the plants or vegetables less susceptible to diseases or pests.

The disadvantage is that you cannot be sure that the nutrient content is evenly distributed. It is therefore important to know what types of nutrients your plants or vegetables specifically need.

How to use humus soil?

Humus soil, made from humus and soil, is used as a nutrient-rich garden soil for soil improvement and landscaping. You can use it to enhance the growth of existing plants, repair damaged lawns or plant new plants.
