Study Notes
Crop Rotation Principles
- Legumes should be rotated with other crops: Legumes have the ability to fix nitrogen from the air into the soil, improving soil fertility.
- Deep-rooted crops should follow shallow-rooted crops: This helps to improve soil structure and drainage.
- Crops that are closely related should NOT follow each other: This reduces the risk of pests and diseases building up in the soil.
- Fallow periods should be allowed during rotation: This allows the soil to rest and recover, promoting healthy soil microbes and improving soil fertility.
Soil Texture
- The relative proportion of sand, silt and clay in a given sample of soil is called soil texture
Vegetable Production
- The most important factor when choosing a vegetable crop is land selection
-
Site selection factors:
- Nearness to market: Reduces transportation costs and ensures fresh produce.
- Topography of the land: Suitable slopes for drainage and sunlight exposure.
- Nearness to sea is NOT a major deciding factor.
Cabbage Cultivation
-
Cultural practices:
- Pruning: Not applicable to cabbage.
- Weeding: Essential to control competition for nutrients and water.
- Watering: Important to ensure optimal growth.
Vegetable Crops
- Examples include potato and tomato
- Cocoa and Cotton are not vegetables
P-Type Semiconductor
- Majority charge carriers are holes, which are positively charged.
Satellite Uses
- Weather forecasting
- Communication
- Scientific exploration
- Navigation (e.g., GPS)
- Television and radio broadcasting
- Military purposes
Alloys
- Brass: Copper and zinc
- Steel: Iron and carbon
- Bronze: Copper and tin
Cultural Practices in Vegetable Production
-
Crop rotation: Helps to maintain soil fertility, control pests and diseases, improve soil structure, and reduce the risk of yield loss.
- Mixed cropping: Growing different types of crops on the same piece of land.
- Mixed farming: Growing crops and rearing animals at different sections of the same piece of land.
- Fertilization: Provides essential nutrients for plant growth.
- Irrigation: Supplies water for optimal plant growth.
- Weed control: Prevents competition for nutrients and water.
- Pest and disease control: Protects crops from damage.
- Harvesting: The process of gathering the crops.
- Marketing: The process of selling the crops.
Benefits of Water
- Hydration: Keeps the body functioning properly.
- Bowel Movement: Prevents constipation
- Metabolic Activities: Essential for chemical processes.
- Stress Relief: Reduces stress levels.
- Improved Skin Health: Promotes healthy and radiant skin.
- Temperature Regulation: Helps to maintain a suitable body temperature.
- Blood Pressure Regulation: Helps to maintain optimal blood pressure.
- Cell Function: Supports the proper functioning of cells, tissues, and organs.
Fuses
- A protective device in an electrical circuit designed to break a circuit if the current exceeds a certain limit, preventing damage to electrical appliances.
