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.

B. Biodegradability Kit
An innovative Environment Science Kit used to conduct experiments to demonstrate materials bio-grading in compounds and liquids of their choice (not supplied). The kit comes with six specially designed containers and a number of clips and cages to hold the materials in place. Supports the teaching of Geography and Science within the National Curriculum framework.
C. Air Pollution - Lichen Identification Charts
A set of colour charts that show how lichen distribution changes with different levels of sulphur dioxide in the air. By identifying the lichens present in an environment, levels of air pollution can be predicted.
