Analysis of Physical and Chemical Properties of Greenland Soil in Yibin City

Studies were made of the soil bulk density and available nutrient status in Yibin City by field investigation and indoor analysis. The results showed that the soil bulk density of park green space, green street, attached green space could meet the demand of plant growth,and yet the soil bulk density of the road affected the plant growth for its relatively big bulk density. The available nitrogen and available potassium could meet the demand of plant growth,but the content of available phosphorus was low,thus needing supplements.
