Soil Physical & Chemical Properties of Different Forest Types in Western Liaoning

There are differences among soil physical chemical properties of different forest types.Xylosma racemosum forest whose soil has loose structure have the stronger infiltration capacity the best physical properties;soil physical properties of Xylosma racemosum forest is the best,followed by Pinus koraiensis,the weed forest whose soil depth penetration rate is only 0.57 mm·min-1 with the soil layer of 10-20 cm is the worst.From the chemical properties,each content of soil nutrient in broad-leaved species is higher than that in coniferous forest.In contrast,the soil nutrient content in Xylosma racemosum forest is higher than that in the weed forest.As the coniferous species,the available nutrient content in the soil of Pinus koraiensis forest is higher than that in the other forest types.
