Because its density is stable enough to provide food and crops from getting drought and erosion
Definitely, soil texture influences soil bulk density
this method is used to determine the field density of soil and bulk density of soil wrt to sand. this method is not suitable for organic , saturated. highly plastic soil that will deform during the excavation of soil.
Generally, the smaller the particles that make up the soil, the greater the density. For example, clay is more dense than sand, and sand more dense then organic soil.
lower levels of organic matter, less aggregation and more compaction
Organic soil cannot contain the chemicals typically used in agriculture.

bulk density depend on that material from which soil formed. so maximum bulk density depend on particle density of that mineral. Therefore,we can only tapped the soil upto perticle density. so maximum bulk density may be occur at equal to paricle density.
i have bulk desity of soil and have natural moisture how can i get unit weight of soil
Bulk density generally increases with soil depth due to increasing pressure from the soil column above. Porosity is inversely related to bulk density, thus porosity should decrease as soil depth increases.
Concerning the second Question: "Can you find bulk density with just this info?"Purely on mathematical insight and analysis:Yes, you should be able to find the bulk density of dry soil, given the 'dry overall' and the 'particle' densities.When wet, there is not enough 'given'Also some should be known about the (or your) definition of porosity
Bulk density is the dry mass of the solids (M sub t) / total volume (V sub t) Particle density is bulk density (P sub b) / 1 minus total porosity (1-theta).
This depends on the bulk density of the topsoil. If we assume a typical bulk density of 1.3g/cc of soil: 1 cubic yard = 764,550cc of soil (764,550cc)(1.3g/cc) = 993,915g of soil (993,915g)/(453.59g/lb.) = 2,191lb. 15(1,191lb.) = 32,865lb.
Humus significantly influences the bulk density of soil and contributes to moisture and nutrient retention. Humus refers to any organic matter, that has reached a point of stability.
6-9Mg of soil in one ha (assuming 1m depth). This variation/range is based on the bulk density; hence, the soil type.
Generally, the smaller the particles that make up the soil, the greater the density. For example, clay is more dense than sand, and sand more dense then organic soil.
Bulk density is a mainly a property of powders, granules and other separated solids, usually used in minerals like soil or gravel. It is defined as the total amount of particles over the total volume they occupy.
