Aquatic plants in nature.
In their natural habitat, streams, puddles and swamps of the tropics, aquatic plants cover large areas but rarely grows mostly on limited areas in groups more or less large.
In these points are, from experience, the so-called elocrene sources of nutrients, ie areas where the soil slowly but steadily flowing water rich in nutrients and CO2.
It is still little known fact that many mineral nutrients in tropical soils can be converted into usable form by plants only from bacteria that live in the humus and humic substances formed by them.
In the bare soil of the tropics - p.e. the edges of new roads - are setting up new plants only after it has formed a layer of humus, even if only a few millimeters thick.
The soil in the habitats of aquatic plants that the more we love, such as the Cryptocorine el'Echinodorus, is rich in humus.
From research and aquarium plants.
During a series of experiments DENNE multi branch company specializing in aquarium plants developed specifically for aquarium bottom material of long-lasting mineral-rich humus.
