Salt content of the soil - Digital

LB3.2.2.5C

Description

The students will investigate the influence of fertiliser on the salt content of soil samples. The salt content is determined indirectly through the conductivity and compared with standard values. The students then learn that fertilising soils increases the salt content and can be the cause of too much salt in the soil, which is detrimental to plants.
