WAYS TO IMPROVE ELECTRICAL CONDUCTIVITY (EC)
As for the control of soil EC, whether it is too high or too low, can be improved by working on the orchard.
First of all, reasonable fertilisation avoids re-accumulation of soil salt and accelerates the level of soil EC. In addition, water with low EC value can be used to irrigate the soil to reduce soil salt concentration. Since salt moves with water, when soil is warm, water evaporates upwards. As a result, salt will accumulate on the surface of the soil. Thus, as long as the surface of the soil is cleared away, most of the salt can be removed from the soil. This method is more thorough and requires heavy workload.
In China, farmers usually practice flood irrigation method. They fill…
