How to test your soil

To see if your land is affected by salt, a few steps need to be taken, such as testing your soil. Special equipment is needed for this, which you may not have at your disposal. We therefore suggest getting in touch with a nearby farmers’ cooperative, who may have access to the necessary equipment.

What steps do you need to take to see if the methods of saline agriculture would work on your land?

Is your soil affected by salt?

Yes No Not Sure

How many samples were taken and how many times did you test?

Less than three More than three

Did you test in different season?

Yes No

Have you determined the salinity level with the protocols before?

Yes No

Step 1: How to take soil samples

Required items:

♦ ‘Tool(s)’ to take a soil sample (eg. Hand trowel, spade, etc)

♦ Test tube or measuring cup

♦ EC meter (An EC meter can be obtained at the following places: Through us for 8 Euros/10 USD (send us an email) / Water equipment or farm supplies shops)

 


How to take soil samples

In this video, you will see how to take soil samples. This is the first step in the process to see if your land is affected by salt and if saline agriculture would be your solution.

You can download the step by step instruction in the link below for an easy reference.

 

Go to step 2

Step 2: How to measure salinity in the soil samples

Now you have collected your soil samples, we need to see if they are affected by salt.

In this video you can see how salinity is measured, using the so-called ‘1:2 method’.
Note: you need an EC meter to be able to follow step 2. 

 

You can download our step by step instruction to perform the test through the below link for an easy reference.

Go to step 3

Step 3: Reference Table: What crops can you grow?

If the results of step 1 and 2 show you have a salinity problem, we need to see what crops could grow on your soil. That depends on the exact salinity level.

The below tables give a general classification of different crops and their suitability for saline agriculture. Keep in mind that of many crops there are very salt tolerant varieties, even under strongly saline conditions yields of for example 75% of the maximum yield is still achievable.

1:2 Method

Value (dS/m) Salinity Crops and varieties
< 1 Low Salinity All crops can be grown
1-3 Moderate Salinity Many common crops such as potatoes, tomatoes, carrots, cabbages, olives, sugar cane, millet.
3 > Strongly Salinity More specialized crops for salinity such as sugar beet, cotton, barley, quinoa or halophytes.
