Peat: what it is and where it comes from
Peat is one of the most important organic materials used in the cultivation of ornamental plants, both natural and combined with other products. It is a carbonaceous formation coming from a progressive decomposition of plant species that live in humid and cold environments, often aquatic. It derives, in particular, from the vegetation in the marshy area of moss and sphagnum. Distinguished by a rather modest calorific value, distilled from acetic acid, it contains one tenth of the potassium and phosphorus present in the manure, and represents the result of a gradual transformation of vegetable residues that has occurred over the centuries. Precisely because of the scarcity of potassium and phosphorus inside, it is not considered a fertilizer in all respects, but simply a soil conditioner. Characterized by a rather high acidity rate, with a pH level between 3.5 and 4, it can be used naturally provided that it is corrected with calcium carbonate, which has the purpose of limiting its acidity. In fact, almost all plant species, except for acidophilic species (as the name suggests), need a soil whose pH is between 5.5 and 6. Furthermore, the possibility of using peat should not be underestimated, and especially the peat coarse, in order to correct the soil when it needs to be made softer or softer.
Blonde peat and dark peat
From a commercial point of view, peat is classified according to the type of structure and color. We speak, in particular, of the degree of grinding, taking into account that tin peat, also known as moss or blond peat, are the most suitable for the cultivation of plant species in pots, and therefore for apartment plants; they offer a fair water retention capacity. Specifically, the coarse-grained and fibrous types allow good drainage and a fair passage of air. Vice versa, for potted plants it is advisable not to use dark peat. Entering the concrete, peat it has the task of making the soil less compact, while improving drainage and aeration. It is used, among other things, to make substrates for greenhouse crops, or to germinate single seeds of species considered delicate. Anyone wishing to buy it can find it on the market in any garden center in bales of variable size and weight.
