This answer doesn't answer the question asked - it does not address *salinity*.

It affects acidity,not salinity.

<p>Organic manure is used in agriculture around the globe.
I am interested in how does organic matter affect the salinity of soil? Does it increases, increases or remains unaffected? and is there a study to support the argument?</p>
