Substrates


US (MI): Managing substrate pH of soilless substrates

Did you know different substrate components in soilless mixes have different pHs? Peat moss and aged pine bark only have a natural pH between 3.0 and 4.0. The optimal substrate pH for most greenhouse and nursery crops, however, is between 5.4 and 6.4 (Figure 1). Therefore, soilless substrate manufacturers.....

Video: Phytosanitary clean peat for bulb packaging

Dutch flower bulbs are exported all over the world. To protect them from damage and dehydration during transport, the bulbs are packaged in sanitized crates filled with peat. Peat with the RHP quality mark is also for this application safe: originating from controlled areas, phytosanitary clean and.....

Substrate handling influences air porosity of substrates

A substrate has four functions: it provides support for roots, it serves as a water reservoir, it serves as exchange sites for nutrients and it promotes the gaseous exchange between the rhizosphere around the roots and the atmosphere. There are many factors that influence the air porosity of a substrate,.....
