Study Notes
Types of Crops
- Cash crop: Grown for profit and sold in the market.
- Catch crop: Fast-growing crop grown between main crops, often used for animal feed.
- Energy crop: Grown for energy production, processed into fuels like bioethanol or biogas.
Kale Characteristics
- Prefers free-draining loam or sandy soil with a pH of 6-7.
- Sowing period: April to July.
- Growing time: Takes 5-6 months to mature.
Kale Usage
- Typically grazed as a fodder crop.
- Harvesting: Usually grazed in situ by cattle or sheep using a strip grazing system.
Grazing Methods
- Zero grazing: Crop cut by farmer and brought to housed animals.
- Strip grazing: Popular method; land must be suitable to avoid poaching.
Kale Diet
- Should be 70% Kale, supplemented with 30% silage/hay.
Kale Storage
- Ensiling: Stored as bales of 'kaleage'.
Advantages of Kale
- Reduces winter feed and housing costs.
- High in crude protein.
- Prevents soil erosion.
- Reduces nitrogen leaching.
- Increases soil organic matter.
- Enhances biodiversity.
Disadvantages of Kale
- Susceptible to pests and diseases.
- Risk of land poaching if grazed in situ.
Kale Pests and Diseases
- Club Root: Soil-borne fungus controlled by crop rotation and resistant varieties.
- Flea Beetle: Controlled by contact insecticide.
