"Leachate" is a generic term used to describe watery run-off from a garbage pile, or a pile of mine tailings. It is generally considered to be hazardous waste, because it can be expected to contain residuals from the pile. What is the source of your leachate?

actually the salt is contained in the fermented fruits and vegetables that i am pre-composting or setting up to pre-compost. to answer your question it is the juice created from the pre-composting.

The nutrients plants take up are salts. The wrong salt can be phytotoxic. Too much of the right salts produce plasmolysis.

Your job is to keep the level of the right salts in the right ratio in the soil solution at levels low enough that osmosis runs efficiently and at levels high enough to prevent nutritional deficiency.

The easiest way to do that is to use a soil that allows you to fertigate from the top, copiously and regularly with a weak solution of fertilizer that meets the criterion I outlined.

Questions?

May I ask what "pre-composting" is? I honestly don't have a clue.

i get my vegetables and fruits from the market. they are not fit to sell but lets say the cauliflower florets are a little brown and the leaves are wilted and the broccoli florets are a little yellow that day. So i pick them up and bring them home i put this food in 5 gallon buckets till i need to feed it to the worms. if i stick a salt meter in the vegetables they show salt content. After they have been packed (pre composted) and broken down i open the buckets if i check the buckets for salt it is off the charts. how do i keep my food supply from getting such a high salt content?

There are two definitions of "salt." The common definition is sodium chloride, or table salt. However, chemists consider the compound formed when an acid and a base are combined, in a solution of water, to be a salt. The second definition is more general, and includes things like potassium chloride, and ammonium sulfate. I don't know why the vegetables you are composting have a high salt content. How are you measuring salt level?

with an inexpensive soil salt meter

Worm bin leachate should not be used on plants - it is not worm tea. Most authorities say not to use it. The people who do use it, say dilute it. Even true worm tea or compost tea is used diluted -typically 10/1. A properly maintained bin will not have leachate. The food should be drained prior to putting in the bin.
All a soil salt meter measures is conductivity. Which gives a overall measurement of all soluble compounds including decomposition acids.
