Nutrients
Our team is experienced in testing for nutrient levels in water and soil. Their detailed analysis is conducted using a combination of discrete analysers, flow injection analysers and ion chromatographs. The list below provides an indication of the broad range of nutrients that can be tested for. Contact us today for more details.
Scope of test
Total nitrogen
Sum of nitrate, nitrite, organic nitrogen and ammoniacal nitrogen. Excess nitrogen promotes growth of toxic blue-green algae and plants in a water body
Total phosphorus
Sum of ortho-phosphate and phosphorus. Excess phosphorus promotes growth of toxic blue-green algae and plants in a water body
Dissolved reactive phosphorus
Mobile form of phosphorus, can promote growth of weeds and algae within a water body
Total dissolved nitrogen
Sum of dissolved inorganic and organic nitrogen. Estimate of nitrogen available to phytoplankton
Ammoniacal nitrogen
Can form ammonia in water which can be toxic to aquatic life. Often tested in of discharge wastewater
Total kjeldahl nitrogen
Sum of organic nitrogen, ammonia, and ammonium
Nitrate
Occurs naturally in soil, commonly used in fertilizers
Sulphate
Found in minerals, soils, plants, rocks, and food. Can be used in fertilizers
