Question 16
Explain how soil characteristics impact on soil development.
Worked Solution & Example Answer:Explain how soil characteristics impact on soil development. - Leaving Cert Geography - Question 16 - 2022
Step 1
Identifying aspect: Soil Texture
Answer
Soil texture, determined by the proportion of sand, silt, and clay, significantly impacts soil development. Soils with high clay content tend to retain moisture and nutrients, promoting the growth of certain vegetation. Conversely, sandy soils drain water quickly, which may hinder development in certain types of plants.
Step 2
Identifying aspect: Soil Structure
Answer
Soil structure refers to the arrangement of soil particles and the spaces between them. Well-structured soils facilitate root penetration and improve aeration, while poorly structured soils can lead to compaction, limiting the movement of air and water.
Step 3
Identifying aspect: Soil pH
Answer
Soil pH affects the availability of nutrients to plants. Acidic soils (pH < 6) may limit the growth of certain crops, while alkaline soils (pH > 7) can lead to nutrient imbalances. The pH level must align with the needs of specific vegetation for effective soil development.
