The first and most significant characteristic of natural resources, including peat deposits, is that no matter how detailed the exploration work may be, it is impossible to determine the exact quantity of reserves in a deposit. To understand this, one needs at least a basic knowledge of geology; for instance, peat is not piled into a regular-shaped pit whose dimensions can be measured to determine the amount of peat within; a peat deposit has irregular boundaries. However, that is the least of our worries – determining the total number of hectares, or the surface area, is not particularly difficult. The problems begin when the thickness of the peat layer needs to be determined. According to Cabinet of Ministers (MK) Regulation No. 570, when conducting geological exploration, the sounding grid is 100 x 100 m (for bogs up to 300 ha) and 100 x 200 m (for bogs over 300 ha). Accordingly, when calculating the quantity of peat, it is assumed that the bottom of the bog is a flat surface. Unfortunately, in reality, this is never the case – peat bogs have formed in both hollows and on hills, the surfaces of which are undulating.
