Abstract

Alkaline and saline soils are regenerated by leaching with acidified water. Acidification is pref. with a phosphoric acid deriv.

Description

Bezeichnung des Erfindungsgegenstandes Designation of the subject of the invention

Verfahren zur Regenerierung von Salzböden und Alkaliböden mit Wasserzuführung Nachtrag zum Schreiben vom 16.3.80 mit neuer Anmeldung.Process for the regeneration of salt and alkaline soils with water supply Addendum to the letter dated March 16, 1980 with a new registration.

Beschreibung.Description.

Es gibt in den Tropen sehr große Bodenflächen, die nicht mehr nutzbar sind, obwohl sie früher hoch produktiv waren. Das betrifft z.B. die stillgelegten Reisanbauflächen im Zweistromland und andererseite auch zu stark ohne saure Mittel beregnete Wüstenflächen.There are very large areas of land in the tropics that can no longer be used even though they used to be highly productive. This applies, for example, to the disused Rice cultivation areas in Mesopotamia and on the other side also too strong without acidic agents irrigated desert areas.

Beide Arten unproduktiver Böden können regeneriert werden, wenn das sogenannte "leaching" mit saurem Wasser erfolgt.Both types of unproductive soils can be regenerated if that so-called "leaching" takes place with acidic water.
