Peat is a natural product derived from the millennial decay of plant species, mainly Sphagnum, in cold and nutrition-deprived swampy. It may have a more or less accentuated decomposition state. Less decomposed peat is a brown colour and has a fibrous and porous structure, good water retention and adequate ventilation. More decomposed peat is a darker brown or black colour with a finer texture, greater water retention and adequate porosity. Both lack nutrition and have high acidity represented by their very low PH.
Agricola 2000 uses peat combined with inert volcanic materials, pumice and lapilli to produce their own soil mixes.
The variables used to compose the product range are:
1. inert volcanic material grain size, which ranges from 0-5 mm to 11-14 mm
2. peat grain size, which ranges from 0-5 mm to 20-40 mm
3. percentage of inert volcanic material in relation to peat
4. the addition of nutrients in relation to quantity and plant transfer rate
5. PH or acidity of the final substrate
The purpose of these variables is to obtain a soil for every application, taking into account the dimensions of the pot used. It ranges from seed hoppers a few millimetres in diameter used for sowing, and pots of various sizes to large-scale planters and terraces used to create roof gardens.
