In laterite soils the particles generally have a specific gravity between about 2.55 and 4.6 (Nanda and Krishnamachari, 1958; Maignien, 1966). However, average decomposed quartz-rich parent materials without a high degree of laterization have a specific gravity between 2.55 and 3.00. This is because quartz, which forms half or …

Introduction. Soil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management. Many of the physical and chemical properties of the soil depend on how ...

If soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.
