Creating grasslands and cultivating forage crops on reclaimed tidal land in winter and early spring can contribute to improving soil physicochemical properties, reducing fine dust, and increasing feed self-sufficiency. Ryegrasses that adapt well to reclaimed land include tall fescue (Festuca arundinacea Schreb.) and Italian ryegrass (Lolium multiflorum Lam.), which are a cool-season perennial and a winter annual, respectively. To evaluate the salt uptake by winter crops and the soil desalinization, tall fescue and Italian ryegrass were grown twice for 3 years on Saemangeum reclaimed tidal land. The nutrient uptake and dry matter yield of crops were low in reclaimed tidal land compared to inland agricultural land, reflecting the nutrient-poor condition of the reclaimed tidal land. The crops removed 6.4 - 10.3 kg ha<SUP>-1</SUP>, 9.8 - 12.5 kg ha<SUP>-1</SUP>, and 4.1 - 12.2 kg ha<SUP>-1</SUP> for Ca, Mg, and Na per winter cultivation, respectively. Soil salinity significantly (P < 0.05) decreased in Italian ryegrass cultivation plot compared with control and tall fescue cultivation plots, reflecting salt removal by Italian ryegrass which was higher in salt uptake than tall fescue. These results suggest that creating grassland and cultivating forage crops on reclaimed tidal land in winter and early spring can contribute to soil desalinization along with the supply of forage containing high concentrations of minerals.
