How is the soil composition in the A horizon related to the composition or the R horizon?
by the topsoil
How can porosity be measured?
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
When is the best time to collect soil sample?
Samples for what? If you are sampling for the basic test that most extension offices perform, it doesn't matter.
Why is it important to know the composition of soil?
One reason is to grow certain types of plants. For example some plants grow well in acidic soil and other grow well in akalyne based soil. If you plant the wrong plants, they won't grow well, or will die within a year or more.
What is the exact chemical composition of soil?

Is soil a homogeneous mixture?
No. It is heterogeneous. The composition of soil varies even within a small sample and the variation is not uniform.
What is the general appearance color how loose or compact it is kind of particles and so forth of the original soil sample?
What is the general appearance (color, how loose or compact it is, kind of particles, and so forth) of the original soil sample?
What is the percentage of sand silt and clay in a sample of soil?
depends on the kind of soil, each kind would have different composition, in fact the kind is defined by the percentage of sand,silt and clay it has.

Earthworms eat the soil, and excrete what they don't digest - leaving tiny piles of 'worm-poop' in the soil. This breaks down and adds to the general composition of the soil.
What are 5 things that a soil sample will tell you?
Porosity, nitrogen levels, phosphorus level, composition (is it made of clay, sand or silt?), pH level.
A typical soil sample is an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.
