Nutrient substrate presents a complex system consisting of macro and microelements necessary for large obtaining plant products, especially under controlled (protected) conditions for producing: tomatoes, cucumbers, peppers in glass and plastic objects. The same refers to the period of nursery plant production as well as growing flowers (trimmed and flowerpotted) at permanent places. Basic components of obtained substrate is organic matter-peat, providing favourable bases, in physical sense, on which root plant system is developed. Zeolite presents an important component of cultivated substrates on the base of organic materials humus, regarding their nutrient values and physical properties (air and water regime). Missing nutrient elements - nitrogen and phosphorus, are compensated by ammoniated zeolite (obtaining NH4-zeolite) and by adding crude phosphate as phosphorus carriers. To provide necessary microelement content, their is a concentrate in substrate, consisting of the following microelements: Zn, Mn, Cu, Fe, B and Mo, in favourable chelate form, contributing complete nutrient substrate value.
