Worked Solution & Example Answer:(i) Explain what is meant by the aspect of a field - Leaving Cert Agricultural Science - Question j - 2015
Step 1
Explain what is meant by the aspect of a field.
Answer
The aspect of a field refers to the direction in which the field is facing. It is determined by the compass direction (e.g., north, south, east, west) that a slope or a piece of land is oriented towards. Aspect can significantly impact various environmental conditions such as sunlight exposure, temperature, and moisture levels.
Step 2
Outline how aspect affects crop growth.
Answer
Aspect influences crop growth in several ways:
- Sunlight Exposure: South-facing fields generally receive more sunlight compared to north-facing ones, allowing crops to photosynthesize more effectively and grow better.
- Temperature: Fields that face south tend to warm up faster in the morning, leading to longer growing seasons and earlier germination.
- Moisture Levels: North-facing slopes may retain more moisture and support different crops that are tolerant to these conditions.
- Yields: The increased sunlight and temperature typically result in higher yields as plants can grow more robustly and produce more grain or fruit.
Understanding these factors allows farmers to make informed decisions regarding crop selection and field management based on the field's aspect.
