Soil Aggregate Distribution in Reclaimed Tidelands and Tidelands of Southwest Coastal Area of Korea

A aggregate size distribution is an important in successful crop production in reclaimed tidelands. The aggregate size distribution for this study were determined of 0.1mm, 0.5mm, 1.0mm, and 2.0mm by wet sieving method. Agricultural activity, period of reclamation showed significant effects on aggregate size distribution in reclaimed tidelands. The percentage of <2mm aggregates for SMG, GHD, and SM reclaimed tidelands were ranged 8.9, 36.7, and 38.0%, respectively. The percentage of >0.1mm aggregates for SMG, GHD, and SM reclaimed tidelands were ranged 9.0, 26.0, and 48.9%, respectively.
