Question

Using the soil classification methods described in the unit, how would you describe the soil in your backyard or closest to your house?
Explain why you would choose this classification and the steps you took to arrive at it.

Answer 1

The aspects of the soil

In order to determine the aspects of the soil we need to know....

• Physical Aspect

The texture of a soil is related to the size of the grains that form it. A soil has different amounts of sand, clay, organic matter, water, air and minerals. The way these components are organized represents the structure of the soil. A well-structured soil should be soft and porous allowing the penetration of water and air, as well as small animals and roots.

• Chemical Aspect

It relates to the nutrients that will be used by plants. These nutrients, dissolved in the soil water (solution), penetrate through plant roots. How we deal in the matter of Macro and Micronutrients.

• Biological Aspect

It deals with living organisms in the soil, which act on the physical and chemical aspects of a soil. Life in the soil is only possible where air, water and nutrients are available. A soil with the presence of living organisms indicates good soil structure conditions. Soil microorganisms are the main agents for chemically transforming nutrients, making them available for absorption by plant roots.

Viewing these conditions, my backyard has a sandy aspect.

• Features of my backyard
• Sandy soil

It has a greater amount of sand than the average (contains about 70% sand). They dry quickly because they are very porous and permeable: they have large spaces (pores) between the grains of sand. The water then passes easily between the grains of sand and soon reaches the deeper layers. Mineral salts, which serve as nutrients for plants, go along with the water. Therefore, sandy soils are generally poor in nutrients used by plants. Need correction and fertilization.

the soil in my backyard is sandy.
