SOIL – Experimental Set with Laboratory Equipment and Worksheets

SOIL – Experimental Set with Laboratory Equipment and Worksheets

A carefully developed set of 20 experiments with explanations for the instructor (from theory to conclusions) and a set of essential laboratory equipment (cylinders, Petri dishes, beakers, pipettes, tweezers, glass vials with stoppers, funnels, sieve and mesh, filters, magnifying glasses, double-ended spatula, soil spatula, etc.) and substances, including a reagent with a colorimetric scale. The set, through simple yet engaging experiments, introduces the most important features and the role of soil in nature. Beginning with soil types and granulometric composition, through physico-chemical properties, we arrive at the role of living organisms in soil, and also the effects of human activity. The included worksheets can be photocopied.

The set also contains colorful laminated panels A4 sheets showing selected stages of some experiments. The entire set is placed in a rigid case. The set has received wide recognition from teachers. Recommended!

Instructions include worksheets with detailed descriptions of the following experiments:

• Soil mineral composition
• Basic soil fractions
• Crumb structure stability of soil
• Soil moisture
• Soil filtration capacity
• Soil water holding capacity
• Soil pH
• Physical sorption of soil
• Effect of calcium- and sodium-containing fertilizers on crumb soil structure
• Effect of liming on soil pH
• Structure of earthworms and their impact on soil fertility
• Soil organisms and their activity in soil
• Variation of soil fauna depending on soil type
• Soil salinity and plant development
• Soil salinity and water uptake by plants
• Effect of soil contamination on germination and growth of plants
• Effect of sodium chloride on soil structure
• Effect of soil acidification on tree condition
