You can add calcium to soil by using lime, gypsum, or bone meal. These products can be spread over the soil and worked into the top few inches. It's important to follow product instructions and conduct a soil test to determine the appropriate amount needed for your particular soil type.
To calculate the mass of soil, you would first need to know the volume of soil you are working with. If you are given the density in g/cm3 and the height of the soil slice (20 cm in this case), you can calculate the volume by multiplying the density by the height. Then, to calculate the mass, you would multiply the volume by the density.
The top layer of soil, called the topsoil, is closest to the surface. It is the layer that contains most of the organic matter and nutrients needed for plant growth.
The topsoil layer contains the greatest amount of decayed organic material, also known as humus. This layer is rich in nutrients and organic matter, making it ideal for plant growth.
The amount of organic matter in the soil typically decreases with depth. In the top layers of soil, organic matter inputs from plant residues and organic materials are more abundant and decompose more rapidly, contributing to higher levels of organic matter. As you move deeper into the soil profile, organic matter content usually decreases due to microbial activity and physical processes.

The amount of peat moss needed to lower the pH level of soil depends on the current pH level and the type of soil. Generally, a good starting point is to mix in 2 to 3 inches of peat moss into the top 6 to 8 inches of soil. It's important to test the pH level regularly and adjust the amount of peat moss as needed.

The mass of any matter is equal to the density multiplied by the volume.

This depends on the bulk density of the topsoil. If we assume a typical bulk density of 1.3g/cc of soil: 1 cubic yard = 764,550cc of soil (764,550cc)(1.3g/cc) = 993,915g of soil (993,915g)/(453.59g/lb.) = 2,191lb. 15(1,191lb.) = 32,865lb.
