In recent years, solving a problem of receiving environmentally friendly food, use artificial natural soil substrata more and more widely: different types of peat, as in "a pure look", and mixes with sand, perlite, vermiculite, mineral wool.
In recent years more and more the preference for creation of artificial soil substrata receives vspuchenny perlite. It is known what the 98th all oxygen to a plant arrives through roots. The soils closed for oxygen lead to the fact that plants die of asthma, the root system in such dense soils develops badly.
Introduction to heavy soils of vspuchenny perlite does soils friable, air - permeable.
Waters has to be much, but it is not enough. The soil has to absorb well water and also it is good to give it to roots of plants. At the same time it is good to spend it minimum and to make waterings less often. Still would be absolutely by the way that water from the soil did not evaporate quickly that the top layer after drying did not form an impenetrable crust.
Vspuchenny perlite is simply irreplaceable here and gives "hundred points" and to mineral wool and expanded polystyrene.
Particles of vspuchenny perlite in the soil are peculiar rezervuarchik with water. When watering perlitovy particles intensively absorb in themselves water and gather it to 400% on weight. While perlite is very hydrophilic, it easily shares moisture with similar perlitovy particles. The layer of earth filled with perlite evenly is humidified. From perlitovy "rezervuarchik" roots of plants will only get water. The particles which gave water to a root it is brought immediately up it from others fuller by water of granules of perlite.
