The Agriculture Test Kit makes it possible to measure pH and the most important elements for plant growth that is nitrogen (N) phosphorus (P) and potassium (K).The chemical composition of soil includes pH and chemical elements. Soil analysis is necessary for better management of fertilisation and to know the residues of fertilisers 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.Testing the soil during each crop cycle and comparing the results with plant growth can be a useful experiment for subsequent cultivations.Order informationThe HI-3896 test kit is supplied with the following;120 mL extraction solution x 270 mL pH indicator75 powder packets (25 each for N P & K)1 mL pipettes x 3Test tubes x 5Test tube standSpoon and brushColour cards x 4Graduated card and handbook
