Research Regarding the Melioration and Agrotechnics of the Salinization Soils From Socodor, Romania

Abstract

Salinized soils from Western Romania occupies approximately 120,000 hectares (40% of the area of salinized soils). The research concerning the melioration and agrotechnics of these soils was carried out in Socodor, Arad County and Diosig, Bihor County.

Research from Socodor is the longest (1957-1998) and is the most known; in existing research center have took the work well known researchers: Vlas I., head of the Center, Colibaș, I., Maria Colibaș, Bundik L., Ilona Bronț, etc.

The paper presents a brief summary of the research regarding the agrotechnics of the salinization soils: types, dosages and combinations of amendments, the behaviour of the various plant species. Also are presented the results obtained in the melioration field through scrubbing salts and their evacuation through drainage; the drains were located at a distance of 5 m, 10 m, 15 m, 20 m, 25 m, at depth of 1,0 m and 1.5 m with ballast or peat as a filter material; the yield results obtained in this field in winter wheat, Lolium multiflorum and sorghum for grain are comparable with the results obtained in the area on unsalinized soils.
