Final answer:
Loamy soil contains a mixture of sand, silt, and humus, the organic material in soil made up of microorganisms and decomposing animals and plant matter.
It also contains varying amounts of clay, air and water as part of its composition. This mix provides an ideal combination of good drainage and high nutrient content, making loamy soil suitable for plant growth.
Step-by-step explanation:
Loamy soil, a particularly beneficial type of soil, is composed of a mix of different sized particles. It contains three key components: sand, silt, and humus. Sand particles are the largest (0.1 to 2 mm in diameter) and they help with soil drainage and air movement. Silt particles are medium sized (0.002 and 0.1 mm) and they provide the soil's ability to retain water and nutrients. Humus, the organic material in soil, is made up of microorganisms (both dead and alive), and decomposing animals and plant matter. This humus vastly improves soil structure while also providing plants with crucial water and minerals. Together, these components make loamy soil ideal for plant growth because it balances good drainage with high nutrient content.
In addition to these, loamy soil also contains various amounts of clay, air and water as part of its composition. Soil ideally contains 50 percent solid material (sand, silt, clay, and humus) and 50 percent pore space which accommodates both water and air.
