WebJun 24, 2024 · The porosity of a soil can be reduced by compaction or be increased by the addition of organic matter to improve a soil's aggregation (structure). Two factors must be known about a soil before its porosity can be calculated: bulk density and particle density (Figure 1). Figure 1. WebJun 14, 2024 · The porosity equation can be used as follows: Porosity (%) = (Volume of Voids / Total Volume) x 100 Porosity (%) = (8 cm cubed / 250 cm cubed) x 100 Porosity (%) = 3.2% The porosity of... mancini\\u0027s sleepworld phone number
