Bearing capacity and shrinkage tendencies are reasons why organic soils are unsuitable for foundation support. Organic soils have low bearing capacity and therefore may not be counted upon to tolerate extensive floor plans and multiple stories. They tend to shrink so more and more of the building will be exposed with time.

What four regional categories of California's soils?
The four regional categories of California's soils are coastal, foothill valley, desert, and mountain soils. Coastal soils are found near the ocean and are characterized by high organic content. Foothill valley soils are found in the inland valleys and support a variety of agricultural crops. Desert soils are found in the arid regions of the state and have low organic matter. Mountain soils are found in the higher elevations and are often rocky and less fertile.
Where do fertile soils get their humus?
Fertile soils get their humus from the decomposition of organic matter such as dead plants and animals. As these organic materials break down, they release nutrients that help nourish plants and improve soil structure. Humus is a key component of fertile soils as it helps retain moisture, improve aeration, and support microbial activity.
In which type soil is wheat grown?
Wheat is typically grown in well-drained loamy soils that are rich in organic matter. These soils provide the necessary nutrients and support good root development for wheat plants to thrive.
What is the difference between forest and prairie soils?
Forest soils tend to be rich in organic matter, have higher acidity, and more microbial activity due to the decomposition of leaf litter and organic debris from trees. Prairie soils, on the other hand, are often characterized by a thicker topsoil layer, higher pH levels, and lower organic matter content, as grasses do not contribute as much organic material as trees.
Why are crops sown in organic soil better than other soils?
organic soils are favorable due to their composition. They contain all the constituents that are required for a plant. Also the uptake of water in other soils. The other biomass present in the soil aid in the healthy season.
What type of soil has the most humas?
Soils with high organic matter content such as forest soils or grassland soils tend to have the most humus. Humus is formed from the decomposition of plant and animal material, and soils with abundant organic matter support healthy plant growth and microbial activity.
What is the difference between mature and immature soils?
Mature soils are well-developed soils that have well-defined soil horizons and a balanced composition of organic matter and minerals. Immature soils, on the other hand, are soils that are still developing and lack well-defined horizons, often having a simpler composition and less organic matter. Mature soils generally support a wider range of plant life compared to immature soils.

Why are desert soils so low in organic matter?
Soils get their organic material from the plants that live, or have lived, in them. Deserts have few plants to provide this material.
In which type soil is wheat grown?
Wheat is typically grown in well-drained loamy soils that are rich in organic matter. These soils provide the necessary nutrients and support good root development for wheat plants to thrive.

Is pile foundation applicable only in soft soil?
It does not meant that pile foundation is only applicable for soft soils alone. For other type of soils it will not be much economical.
Why do clay and organic soils hold nutrient better then sandy soils?
Clay and organic soils hold nutrients better then sandy soils because the sandy soils as the water drains away, the water will carry the nutrients with it. This is called leaching and the nutrients will not be available for the plants to use.

Why are are desert soils low on organic matter?
There are few plants in the desert to provide the organic material.
