Worked Solution & Example Answer:Explain why a good seed bed is essential for successful crop production - Leaving Cert Agricultural Science - Question c - 2006
Step 1
Explain why a good seed bed is essential for successful crop production.
Answer
A good seed bed provides several essential functions for successful crop production. First, it offers support for the plant; the soil structure allows roots to anchor securely. This stability is critical for nutrient absorption and moisture retention.
Additionally, a well-prepared seed bed ensures proper aeration of the soil, which is vital for plant respiration. The seeds benefit from good soil-seed contact, which enhances germination rates. Furthermore, it facilitates easy access to nutrients that are necessary for growth.
Step 2
Outline the importance of soil moisture in the development of a seedling of a crop.
Answer
Soil moisture is crucial for various reasons. It is involved in the intake of water by roots through osmosis, enabling the plant to transport necessary nutrients for growth. Water is needed for physiological processes, including photosynthesis and turgidity, which keeps the plant structure firm. Furthermore, adequate moisture levels prevent seedling stress, allowing for healthy development and growth.
Step 3
Explain why farm implements called rollers are used during the cultivations of a named cereal crop as follows:
Answer
-
Preparation of soil for sowing: Rollers are used to break large clods, leading to a smoother surface and firming the soil, which aids in proper seed placement and soil contact.
-
After sowing the seed: Rollers compact the soil around the seed, improving water intake and creating better conditions for seed germination by enhancing capillarity.
