The structural substrate is intended for planting trees and greenery, especially in cities and industrial zones. It is used in places with limited soil air exchange, such as built-up and paved city streets, parking lots, etc., or in locations with unsuitable clay soil. The aim is to create the necessary root zone with sufficient air exchange to ensure healthy plant growth. It is used to prepare the planting mixture on site by mixing it with soil, sand, and gravel.

Composition of raw materials: activated carbon, bark compost, dolomitic limestone, mixed fertilizer

The peat-free structural substrate is made from renewable resources. It uses parts of plants that would otherwise increase the amount of waste produced. It contains a mixture of compost and activated carbon – carbonized biomass enriched with nutrients. The compost component is a natural reservoir of nutrients for plants. The carbonized component lightens the soil and improves its structure. It contains a huge number of pores. It increases the soil’s ability to retain water and nutrients. Activated carbon is obtained by carbonizing biomass. During this process, organic carbon is converted into a permanent form that is practically non-degradable, thus ensuring a permanent structure for many centuries. According to current knowledge, this is an effective permanent storage of carbon obtained from the atmosphere by plant biomass during photosynthesis from carbon dioxide.

Recommendations for use:

Mix the structural substrate in a suitable ratio with gravel or coarse sand or soil, depending on the intended use. To ensure sufficient air for tree roots and water infiltration and retention, especially in areas under paved surfaces (paved sidewalks, parking lots, etc.), it is used in a mixture with coarse gravel (approx. up to 40 mm) in a ratio of 15% substrate by volume and 85% gravel. On the other hand, for the top layer of soil for planting and flower beds, the structural substrate is used in a mixture with soil and, if necessary, sand. To enrich the soil for planting in flower beds, we recommend using up to 30% structural substrate mixed with soil and, if necessary, sand.

Substrate for sowing even the most demanding types of seeds, including coated seeds, for vegetative propagation of woody and herbaceous cuttings. For pre-cultivation of the youngest plants requiring a neutral pH.
Balanced, very fine structure, up to 8 mm without long fibers. Very low bulk density, high water absorption, non-clumping, structured, airy, weed-free, non-saline, free of disease and pest germs.
