After calculating the mass of the soil layer, do I simply multiply the concentration of calcium by the mass? I would end up with an answer with mg as the unit. Do I then convert mg to kg/ha? How do I do that?
The layer of the soil (for which you calculated its mass) has area of 1 ha (which is 100 m by 100 m); hence, the only conversion that you need to do is from milligrams to kg.
