GLEBA: human influence experimental set

MACHINE TRANSLATION (not authorised yet)

Set of 8 experiments with a discussion for the teacher (from theory to conclusions) and a set of necessary laboratory equipment (dishes, beakers, pipettes, vials, magnifying glasses, soil spatula, baguette, etc.) together with necessary substances and indicator solution and colorimetric scale. The set, by means of simple but interesting experiments, acquaints with the effects of human influence on soils. The topics of the exercises include: the effect of soil contamination on plant growth, soil salinity, the effect of sodium chloride on soil structure, the effect of selected fertilizers on soil tuberculosity and its pH. The attached work sheets can be copied. The experiences included in this set are part of "GLEBA - a set of experience with laboratory equipment and work cards".
