A soil sample with large amount of space between the particles will have a?
high porosity
What is soil porosity?
It is defined as the ratio of its pore volume to the bulk volume.Has miniscule holes
How does the porosity vary with the amount of clay in the soil?
The voids present between the soil particles are called pore space and the size of these pores depends on whether the ore is between the soil particles or between the soil aggregates. In general, in cultivated lands, soil particles do not exist as single grains and therefore, there are only voids within the soil aggregates or peds and voids between the aggregates. As clay particles play a major role in the formation of soil aggregates by way of binding the soil particles, the particles within the aggregates are micro pores and between the aggregates are macro pores. Depending on the amount of clay particles, the proportion of micro to macro pores may vary and in most cases the soils containing more clay particles favour aggregation and thereby the micro pores and total porosity.
Why is the size of rock particles important to soil structure?
The size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage.

What is the relationship between the spaces between particles in soil and the flow of water through soil?
In general the larger the pore space (the higher the porosity) the easier it is for water to flow through it (it is more permeable).
Does the soil porosity increase as the depth increases?
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.
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.
What factors control evaporation on a soil surface?
Factors that affect evaporation include temperature, humidity, wind velocity, exposed surface area, porosity of soil, grain size of soil particles, soil water content, matric potential, and sun intensity.
Why is the size of rock particles important to soil structure?
The size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage.

When A dry soil sample has a volume of 500 mL After 400 mL of water are added to the soil the soil becomes saturated with 150 mL of surface water left on top What is the porosity of the soil?
the porosity is 50%
