| Abstract: | A study was conducted to analyze surface chemical properties of 16 mixed soil samples collected from 11 ramp zones of Heda highway(Mudanjiang-Jiamusi).Soil physical and chemical properties were determined,including soil texture,pH value,moisture content,and contents of organic matter,ammonium nitrogen,available phosphorus and available potassium.Results showed that pH value of soils in all the study sections of ramp zones ranged from 6.5 to 7.5,close to slightly acidic or neutral,which can guarantee the pH ... |
