Measuring Soil nutrients.

 Soil nutrients are essential for high agricultural productivity, which can only be obtained when all nutrients are in the optimal supply range. Plant available phosphorus can be used as an indicator of chemical soil nutrients as it is a stable element, and its mobility in the soil is limited. When measuring soil nutrients, laboratories may provide a complete analysis containing values for nitrogen (N), phosphorous (P) and potassium (K). Plant available phosphorus was chosen given the nature of its mobility, but N and K can also be consid
