Investigation of the chalk content of garden soil, sand and further soil samples.The chalk (lime) content of the soil is important for plants in several respects. It affects the quality of the soil, e.g. its acidity, heat retention capacity, water balance and aeration. In addition calcium, an antagonist of potassium, plays a direct role in swelling processes and is also a plant nutrient.
