So, here are things to look out for when choosing soil for your snails

  1. Soil Texture: Soil texture is the percentage of sand, silt and clay in the soil. It accounts for how fast water can penetrate the soil, a soil with higher clay content will have low porosity and therefore, water will find it hard to penetrate such soil, these types of soils are not good for snail farming.
  2. Chemical component of the soil: this, you will hardly notice by just mere looking at the soil but when subjected to laboratory test, you will be shocked to know the level of chemicals in some soil, so how do you solve this issue? By treating the soil, soils with high chemical content are not good for snail farming.
  3. Soil color: Most dark colored soils are suitable for snail farming, this is because, the dark color is mostly as a result of decayed organic materials so, this type of soil stand a chance in snail farming.
  4. Presence of metals: Soils that have metals present in them are not good for snail farming no matter how small the materials are, they can harm your snails, and therefore should be avoided.

So, what kind of soil is best for snail farming?

Sandy-loam soil is the best soil for snail farming and here are the reasons why it is the best soil for snaiol farming.

Why Sandy-Loamy is the best soil for snail farming

 Here is why sandy-loamy soil is the best soil for snail farming

  1. Low water holding capacity: sandy-loamy soils contain moderate water holding capacity, they do not support water-logging, they allow free movement of water in and out of the soil.
  2. Presence of organic matter: Sandy-loamy soil contains a considerate amount of organic materials, this is something snails enjoy a lot.
  3.  Rich organic minerals: Sandy-loamy soil is rich in organic minerals, these minerals are needed by snails.
  4. Lack of toxic checmical substances: Sandy-loamy soils are mostly free of toxic chemicals, this is due to the presence of organic matter in the soil.

Snails love moderately cool environment, the reason why they are always seen in the bush after rain.

Snails prefer Soils with high organic matter because they support the growth and development of snails. In general, if a soil supports good growth of cocoyam, tomatoes and leafy vegetables, it is most definitely suitable for snail farming.

Even after getting your sandy-loamy soil, it is still not advisable to just pour the soil into your pen, introduce your snails and start feeding them, No.

Before introducing the soils to to the pen, the soil should be treated and made suitable for snail farming.

  • Turn/mix the soil while applying the chemical, this will ensure that the chemical gets  into every part of the soil.
  • Allow the soil to rest for three hours after applying the chemical before taking them to the pen.

Chemicals are applied to the soil using knapsack.

The soil is then left to dry for 6-7 hours before they are introduced into the snail pen.

How to treat soil for snail farming using air Drying method

In this method,

  • Collect the required amount of soil with a shovel.
  • Transfer the soil to an open area, spread the soil (preferably on nylon).
  • Allow the soil to stay exposed directly to the sun for 7-9 hours.
  • Turn the soil after every one hour so as to allow the sun penetrate all parts of the soil particles.

A harsh climatic condition caused by the direct exposure of the soil to the sun will cause every insect or harmful organism (s) to leave the soil thereby making the soil safe for snail rearing.

Collect the soil after drying it, water it and pour them into the snail pen before the introducing your snails.

How to treat soil for snail farming using burning method

In using burning method,

  • Collect the needed amount of soil with a shovel.
  •  Move the soil to an open area.
  • Pour the soil inside a metal.
  • Born the soil for 1-2 hours, the heat from the fire kills insects and organisms in the soil making it suitable for snail farming.
  • Transfer immediately to the pen and allow the temperature to cool for 20 to 30 hours before introducing your snails.
  • Add water to the soil to make it moist and suitable for snails.

It is very important that the soil is made fit for the snail to survive on before introducing your snail else you risk getting the snails killed to give the soil time to cool.

How to treat soil for snail farming using hot water

This method involves the introduction of boiled water in a soil filled container

  • Collect the soil from the field with a shovel.
  • Boil big quantity of water (very hot).
  • Pick a big metal pot  and pour a little amount of water inside the pot
  • Add the hot water inside the pot containing the soil
  • Add more soil and water, while you add the soil, also add water, this way, every part of the soil will be touched by the water.

The hotness of the water will kill any insect, organism or micro-organisms in the soil, making the soil fit for snail farming.

The Importance of treating the soil for snail farming

  • It keeps the soil free of germ and harmful insects.
  • It ensures healthy snails; snails consume the soil they find themselves in, if the soil is not germfree, it will be harmful to the snail
  • Reduces cost of management, infected soil is like a pathogen, if not treated, the snails are at risk of getting infected, the money will be spent on vaccination, treating the soil ensures fewer expenses on vaccination
  • It promotes neatness.


Insects, termites, and other organisms in the soil can be very harmful to snails if not properly taken care of, the reduction or complete eradication of these organisms in the soil through soil treatment before introducing the snails is an important managerial practice.

It mediates the presence of infectious insects and germs, ensures healthier and cleaner snails and productivity.

Snail farmers are encouraged to carry out this practice for better, healthier, and productive snail farming. It should be done properly to obtain the required result.
