Four Components of Soil
What is Splash Erosion
When soil is thrown by the force of a raindrop impact.
What is O Horizon
Mostly non-decomposed plant litter called humus.
Lack of three macronutrients can slow plant growth:
Nitrogen (N), Phosphorus (P) and Potassium (K)
Do calories come from one of three macronutrients?
Carbohydrates, Lipids and Proteins.
Soil Made of 3 Particles
Sand, Silt and Clay
What is Rill Erosion
When water flowing down a slope carves small channels into the land.
What is A Horizon
They called topsoil, contains a lot of organic matter mixed with some materials.
What is Synthetic Fertilizer
They are made from mined minerals.
What is Undernourishment
The result of a diet that does not meet an individual's basic energy (calories) requirement.
What are the Four Main Loam?
Ideal Soil, Rich In Nutrients, Retains H2O and Drains Well.
What is Sheet Erosion
The removal of a thin layer of soil from a large area.
They are called subsoil, which has very little organic matter. Instead, it is mostly made of small particles of clay minerals.
What are Organic Fertilizers?
They are derived from plant and animal matter.
They are caused by insufficient protein consumption, resulting in a fluid imbalance in the digestive system.
Why is it important to know the Soil Type?
Select Plants or Crops that grow well in soil type
Understand why your plants/crops aren't growing well.
Know how to fix the foil (Fertilizers, Organic Materials)
What is Gully Erosion
The most severe, caused by rapidly flowing water creating deep channels in the ground.
What is C Horizon
They called substratum, contain mostly rocks.
What is Animal Manure
The dung and urine of livestock.
What is Anemia
The name of any condition that results in a decrease in the ability of blood to transport oxygen.
What are the Soil Labs
Mason Jar Lab
Soil Texture
Ribbon Testing
The transportation and deposition of soil particles due to air currents.
What is Parent Material
This is an unweathered layer of rock that the soil originated from.
What is Compost
The organic matter has been decomposed by bacteria, fungi, and other microorganisms.
