How to Determine Soil Fertility Without a Laboratory: A Simple Experiment with Cotton Fabric
You can determine the fertility level of your soil using a simple and unusual method, without resorting to laboratory analyses — by using ordinary cotton fabric.

A Simple Experiment to Assess Soil Condition
European farmers suggest an interesting approach: bury an old, unwashed cotton fabric at a depth of about 15 centimeters in the center of your garden. The best time for this experiment is summer or warm autumn when soil microorganisms are particularly active. After burying the fabric, leave it undisturbed for two months.
During this time, active processes unfold underground: bacteria, fungi, worms, and other soil inhabitants decompose organic matter. The cotton acts as a sort of litmus test: if the fabric has nearly completely disappeared or is significantly damaged, this indicates a healthy, life-rich soil. If the fabric remains unchanged, it may suggest a deficiency of beneficial microorganisms or excessive use of chemicals.
What to Do If the Soil Turns Out to Be “Poor”
If the experiment shows insufficient activity of the soil biota, it is recommended to improve the condition of the area by adding compost, manure, green fertilizers, or mulch. Such actions will help restore the balance of organic matter and stimulate the development of beneficial microorganisms. After a season, the fabric experiment can be repeated to assess changes and the effectiveness of the measures taken.
“Soil that ‘eats’ fabric is alive. The essence of this amusing experiment is simple: bury a piece of unwashed cotton fabric at a depth of about 15 centimeters in the middle of your garden. The key is not to spare the fabric, as it will serve as the litmus test for your fertility. The more actively the soil ‘consumes’ it, the more life is hidden beneath the surface.”
This method is not only an interesting experiment but also an effective way to assess the biological activity of the soil and to timely care for its restoration.
