Study Notes
Cover Crop
- Cover crops protect and enrich the soil, managing erosion, fertility, and quality.
- They can grow after cash crops and may thrive over winter.
Cash Crop
- A cash crop is cultivated primarily for profit, rather than subsistence.
Catch Crop
- A catch crop is a fast-growing crop sown between main crop plantings, often for animal feed.
- Kale serves as an example of a catch crop but is also classified as a cover crop.
- Ploughing catch crops back into soil enhances soil structure.
Other Catch Crops
- Cabbage and rape are additional examples of catch crops.
Advantages of Catch Crop (Kale)
- Enhances soil quality.
- Provides additional feed for livestock.
- Improves land productivity in transitional periods.
Disadvantages of Catch Crop (Kale)
- Risks of competition with main crops.
- Costs associated with planting and maintenance.
- Limited marketability compared to cash crops.
Energy Crop
- Energy crops are cultivated for energy production, not food.
- They are processed into various fuels like bioethanol and biogas but are not the focus here due to the choice of Kale as a catch crop.
Growth Cycle of Kale
- Specific growth cycles are essential for successful cultivation but details are indicated as omitted.
Cultivation of Kale
- Specific practices are essential for growing kale effectively but details are indicated as omitted.
Seedbed Preparation
- Importance of creating a well-structured seedbed prior to sowing for optimal crop establishment.
Fertilizer Requirements
- Kale has specific nutrient needs; details on types and quantities are omitted.
Weed Control
- Strong germination is vital for weed management, ensuring crop establishment outcompetes weeds.
- Glyphosate should be applied prior to sowing to eliminate existing weeds and prevent competition.
- Limited herbicides are effective for kale in comparison to others.
Disease Control
- Club root, a fungal disease, poses a significant threat to kale, causing root degradation.
- Implement a one in five-year crop rotation to curb club root presence, which can remain viable in soil for up to 20 years.
Pest Control
- Flea beetles harass young crops; insecticides are required to mitigate damage.
- Slugs can be managed with bait pellets.
- The diamond back moth caterpillar is the most destructive pest for kale, requiring insecticide treatments.
Harvesting of Kale
- Specific harvesting practices are necessary for kale; detailed information is not provided here.
