Agriculture Test Kit, Professional Cat.No. HI 3896

The chemical composition of soil includes pH and chemical elements. Soil analysis is necessary for better management of fertilization and to know the residues of fertilizers in relation to the crop, tillage and the most suitable plant choice for soil composition. An analysis can highlight shortages and help the understanding of the causes of an abnormal growth. By using the HANNA Soiltest, it is possible to measure pH and the most important elements for plant growth, that is, nitrogen ( N) , phosphorus ( P) and potassium ( K) . Testing the soil during each crop cycle and comparing the results with plant growth can be a useful experiment for subsequent cultivations.
