About this course

The subject includes lectures on soil analysis theory and how soil analyses are used as a tool for fertilization and liming planning, as well as for assessing pollution potential. In the laboratory, the following soil analyses are conducted: soil pre-treatment, bulk density determination, dry matter and loss-on-ignition determination, pH analysis, and analysis of easily soluble (plant-available) potassium, magnesium, calcium, phosphorus, and nitrogen. Exercises using DGT will also be conducted to determine the kinetics of phosphorus in soil from field trials with different phosphorus treatments
