Environmental Change Network core measurements at Alice Holt Forest - soil solution chemistry

 

Soil solution samples are collected using twelve Prenart ‘super quartz’ soil water samplers. Six samplers are installed in the A horizon and six at the base of the B horizon. Each sample is analyzed for:

• Volume (mls)
• Vacuum (bars)
• pH
• Conductivity (μS)
• Alkalinity (mg l^-1)
• Sodium Na⁺ (mg l^-1)
• Potassium K⁺ (mg l^-1)
• Calcium Ca²⁺ (mg l^-1)
• Magnesium Mg²⁺ (mg l^-1)
• Iron Fe²⁺ (mg l^-1)
• Aluminium Al³⁺ (mg l^-1)
• Phosphate PO₄^3--P (mg l^-1)
• Ammonia NH₄⁺-N (mg l^-1)
• Chloride Cl^- (mg l^-1)
• Nitrate NO₃^--N (mg l^-1)
• Sulphate SO₄^2--S (mg l^-1)
• Dissolved Organic Carbon (DOC)
