Studies on the suitability of soil classes for the barley cultivation before rice transplanting in the honam china area

When barley was cultivated before rice transplanting it was carried out during 1983 to 1985, for the effective improvement and management of the soils to investigate the morphological and physicochemical characteristics of the soils, and the field potential centering around the demonstration fields of barley variety. The results obtained were as follows; The grain yield of Noryeog-Sobaeg mountainous region was the smallest among investigating and the soils were graded the 3th but those were graded the 1st or the 2nd in else-regions. Grain yield was significantly negative correlates with the topography (r = 0.372**) permeability (r = 0.318**) and runoff (r = 0.409**) out of soil characteristics. A significant negative correlation was obtained betwene grain yield with Ca (r = 0.393*) and SiO2 (r = 0.458**) out the chemical characteristics of soils. Main factors of the standard of grade classification for barley cultivation of cropping before rice transplanting were topography, texture, drainage, slopes, available soil depth, Oxygen availability, water availability, permeability, runoff etc, and it was set with five classes according to their contribution coefficient. It was 21,45,17,15,21, in order that the number of phases was graded from the 1st to the 5th for barley cultivation in the paddy soils of Honam area. The suitable soil for barley cultivation were from the 1st to the 3rd classes and were 81.7% in total paddy soils of Honam area.
