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.....

How substrate structure influences air porosity

Roots need oxygen for respiration. The amount of air required in the substrate is going to depend mostly on its total porosity. Total porosity is the percentage of the total volume of substrate that it is not occupied by solids and is composed of both air and water. Air porosity is the percentage of air.....
