Soil Flashcards
Name the 4 layers of soil
Humus
Topsoil
Subsoil
Parent rock/Bed rock
Name 4 types of soils
Brown earth soil
Podzol soil
Grey soil
Peaty soil
Tell me about brown earth soil
Most common in Ireland
Found in lowland areas
Even loads of sand and clay equal loom soil
Developed on boulder clay
Fertile
Deciduous forest developed on this oil producing plant which provides with humus and various leaching occurred, which is very good for agriculture
Tell me about podzol soil
Configures forest developed on the soil
NOS common Ireland
Infertile and acidic
Loss of leading due to heavy rainfall
Cold and wet, very little earthworm activity
Found in potty trained areas such as county Galway and Cork
Name the five factors of soil formation
• Climate
• Parent material
• Living organisms
• Landscape/relief
• Vegetation
• Time
Define the term climate in relation to soil
Broken down by weathering to form mineral matter depending on rainfall plus temperature. Excess rainfall leads to leaching parents rock is broken down by chemical weathering this impact types of vegetation.
Define the term patent material
Type of rock broken down my weathering. These provide manners and nutrition forming stones and very fertile.
Define the term living organisms in relation to soil
Bacteria, fungi breakdown plant litter in the O horizon. Earthworms break up soil when they die they add nutrition to the soil.
Define the term landscape/relief in relation to soil
Upland Soils are thin because of mass movement and poorly drained. Low land soils are deeper rich in humus and fertile.
Define the term vegetation in relation to soil
Create plant litter which breaks down humans. Areas with deciduous trees have more plants litter therefore more fertile soils.
Define the term time in relation to soil
It can take up to four hundred years for one centimetre of soil to form because the process is so slow. As soil is a non-renewable resource
Define the term loam
It is an even mixture of soil slit and clay. Soft and texture and they break up easily and are ideal for growing crops.
Define the term mineral matter
Main ingredient in soil is rock particles weathered and eroded. Provide mineral to help plants grow.
Define the term air in relation to soil
Fills Space between particles and contains oxygen and nitrogen. Living organisms need it to survive.
Define the term water in relation to soil
Help bind soil together. Minerals dissolved in water absorbed through the root of plants.
