Soil: physical and chemical properties

MACHINE TRANSLATION (not authorised yet)

Set of 7 experiments with a discussion for the teacher (from theory to conclusions) and a set of necessary laboratory equipment (cylinders, scales, beakers, pipette, tweezers, vials, funnels, sieve, sifts, magnifying glasses, double-sided spatula, soil spatula...). and an indicator solution with a colorimetric scale. The set, by means of simple but interesting experiments, acquaints the basic physicochemical properties of soil, such as: mineral composition, basic soil fractions, soil structure, moisture, filtration capacity and water capacity of soil, soil pH reaction, physical sorption of soils. The attached work sheets can be copied. The experiments included in this set are part of "GLEBA - Experimental set with laboratory equipment and work sheets".
