Solution | Determination of the Contents of P, K, Ca, and Mg in Soil Fertilizers by the ICP Method
Release Date：2026-11-04
Soil serves as the lifeline that sustains ecosystems and agricultural production; the precise determination of its nutrient content is directly linked to crop health, environmental safety, and the sustainable utilization of resources. Among the various soil elements, the detection of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), iron (Fe), and manganese (Mn) is particularly critical. As the "energy engines" of plant growth, phosphorus and potassium participate in photosynthesis, energy transfer, and root development; therefore, the determination of their available forms provides a core basis for scientifically informed fertilization. Calcium and magnesium not only influence soil structural stability and acid–base balance but also serve as key regulatory factors in the formation of plant cell walls and enzyme activity. Although trace elements such as copper, iron, and manganese are required in only minute quantities, they act as "catalysts" for plant enzyme systems and metabolic activities; their abundance or deficiency directly constrains crop stress resistance and yield.
