Improvement possibilities of soil quality [articol]

Abstract

In this paper we follow the effects of adding zeolitic tuff (clinoptilolite rich tuff) in soil for treating.Because of it’s essential features and structure this high-silicon type generates in soil an effective pH buffering process, an increase of soil humidity and the enrich of cationic content in soil solution. The applying of zeolitic tuff on soil is beneficial for the enhance of cationic exchange and soil adsorption processes. Alone or in mixture with organic nitrogen fertilizer the tuff supplies establish in soil the enhance of global soil fertility particularly in the neighborhood of rizosphere, rising the crop production.
