Soil scientists and engineers commonly require bulk density (Db) data as parameter input of simulation models predicting a wide range of soil processes. Field methods exist to measure Db, but are labor intensive and time consuming. Much effort has been recently devoted to evaluate alternative proced...
Bulk density—is the density of a volume of soil as it exists naturally, it includes air space, organic matter, and soil solids. Natural root growth is restricted as BD becomes greater than 1.5 g cm−3 in fine-textured (clay and silt) soil and at 1.7 g cm−3 in course-textured ...
Infiltration measurements were made on swelling clay soil samples packed into columns. Small increases in bulk density over the range 1.10 to 1.25 g/cm3 markedly decreased the rate of water movement. The magnitude of the effect was greater for confined samples than unconfined samples at all initial...
The main objective of this work was to investigate the dependence of bulk density on texture, organic matter content and available nutrients (macro and micro nutrients) for soil of Coimbatore. The relationships between some physical and chemical properties of soil such as, clay content (C), silt...
The assessment is based on the maximum of bulk density attained using the Proctor test (MBD). In this study the soil texture is expressed by silt plus clay (S + C) or clay (C). The relations between the soil texture and MBD, and between soil texture and critical water content (CWC—...
aAdd compost to provide bulk to compacted, dense, clay soils. Compost lightens soil and encourages worms and microorganisms, which aerate soil. Add compost to light, sandy soils to retain essential nutrients, minerals and moisture. When planting annual seedlings, add compost to the growing hole....
The effect of changing water content on the bulk density of undisturbed cores of a cracking clay was examined in laboratory experiments. The results were compared with the relationship between bulk density and water content established b... R Berndt,K Coughlan - 《Soil Research》 被引量: 84发表...

Soil bulk density is a dynamic property that varies with the soil structural conditions. The relationships between some soil physical and chemical properties such as, clay content (C), silt content (Si), sand content (S), very fine sand content (Vfs) and organic matter content (OMC) with ...
