The total porosity is defined as: WebNanoaluminum oxides reduce the bulk density and enhance the percentage of void spaces in soil (Taha and Taha, 2012). Soil porosity and bulk density are contrarily in proportion. NPs can affect pores ratio (micropores and macropores). NPs rich soils such as allophane and imogolite have low bulk density due to the high microporosity (Zhang, 2007). WebSoil Porosity = ( 1 - (Bulk Density ÷ Particle Density) ) x 100. This will indicate the percentage of the soil that contains pores. Using some previously calculated figures, if a sandy soil, with organic matter content of 20%, has a bulk density of 1.4 g cm-3, and an average particle density of 2.222 g cm-3 then the soil porosity is as follows: how body uses potassiam
