__________ soil is considered ideal for food production, usually nutrient-rich, and holds both air and water well.
__________ soil is considered ideal for food production, usually nutrient-rich, and holds both air and water well.
Loamy soil is a mixture between sand, silt, and clay. It is rich in organic matter, and the properties of sand and clay combined allow it to hold air and water well.

What are the three main types of soil?
What are the three main types of soil?
Silt, clay and sand are the three main types of soil. Loam is actually a soil mixture with a high clay content, and humus is organic matter present in soil (particularly in the top organic "O" layer), but neither are a main type of soil.

List these types of soil by their particle size from largest to smallest.
List these types of soil by their particle size from largest to smallest.
Sand is defined as having a diameter ranging from 0.05 mm to 2 mm, silt as having a diameter ranging from 0.05 mm to 0.002 mm, and clay as having a diameter smaller than 0.002 mm. Therefore, sand particles are the largest, followed by silt, and then clay being the smallest particles in the spectrum.

Brett has been collecting soil samples from various city parks for his chemistry class. The chemistry class will measure the amount of nutrients, such as potassium and nitrogen, in each soil sample. The park with the best quality soil will be the location of a community garden. By measuring the soil nutrients, what soil property is Brett trying to quantify?

The correct response is soil fertility. The amount of nutrients in the soil is a measurement of soil fertility. Soils with high nutrient content (especially with respect to nitrogen, phosphorous, and potassium) are considered fertile soils. Soils with low nutrient content are considered infertile soils. Soil porosity refers to the amount of air space between soil particles. Soil infiltration refers to its infiltration (absorption of water) capacity. Soil compressibility, as the name suggests, is the ability for a soil to be compressed. Soil strength involves the capacity of a soil to withstand sheer stress forces, which is influenced by many parameters including those mentioned above.
