  • Phosphorus Common in natural systems, such as lakes, oceans, and soil, phosphorus is an essential element for plant and animal growth. However, when present in large concentrations, phosphorus can cause excessive microorganism and algae growth. For this reason many wastewater treatment plants monitor the total phosphorus that is discharged. It is one of the primary nutrients that is removed chemically or biologically. For hobbyists with saltwater or freshwater aquaria, a high amount ...

  • Phosphate Phosphates are used in a number of everyday products, such as cola drinks to enhance flavor and tartness, antifreeze as a pH buffer, and french fries to delay darkening of the cut potatoes. They are also extensively used in detergents and cleaning fluids because of their ability to soften water and remove soil deposits. Phosphate is essential for the growth and development of plant roots, stems, flowers and seeds, and is commonly added to fertilizers. However, high concentrati...
  • Potassium The three elements that are most needed by plants are nitrogen (N), phosphorous (P), and potassium (K). Even though potassium is not a constituent of important compounds, it plays a remarkable role in many physiological activities in plants like the control of cellular turgor and the accumulation of carbohydrates. It increases the size of fruits, their flavor, as well as yielding a positive effect on the color and fragrance of flowers. Because of its influence on plant growth,...
  • Nutrient Analysis (NPK) The chemical composition of a nutrient solution includes differnet chemical elements. Nutrient analysis is necessary for better management of fertilization and to know the residues of fertilizers in relation to the crop. An analysis can highlight shortages and help the understanding of the causes of an abnormal growth. The three elements that are most needed by plants are nitrogen (N), phosphorous (P) and potassium (K). Nitrogen (N) is indispensable for the pl...
  • Magnesium Magnesium is one of the main ionic species in water which causes hardness. Magnesium is also an indispensable mineral that helps in the production of chlorophyll, the light-absorbing green pigment that serves as an energy source for plants. It also increases vitamin concentrations and aids in uptake of phosphorus within the plant body. Magnesium can be measured photometrically with reagents. Photometric analysis is based on the Beer-Lambert principle of absorbance in which ...
