    Study Notes

    Botanical Families of Vegetables

    • Broccoli, cabbage, kale, Brussels sprouts, radish, rutabaga, and turnip belong to the Brassicaceae family.
    • Tomatoes, peppers, potatoes, eggplants, and tomatillos are in the Solanaceae family.
    • Winter and summer squash, melons, cucumbers, and pumpkins belong to the Cucurbitaceae family.

    Crop Rotation Strategies

    • Keeping detailed records and creating maps of your garden can aid in efficient crop rotation.
    • Flashcards can be used as a visual aid for tracking crop rotation, with separate cards for each crop and each year in the rotation schedule.
    • Using the botanical family as a guide for rotation is recommended. For example, rotating crops within the same family over a 3-5-year timeline.

    Soil Management

    • Organic fertilizers require warm soil to decompose and release nutrients.
    • Soil testing and adjusting pH levels using lime are important for optimal soil conditions.
    • Calcium, the neutralizing agent in lime, takes time to spread. Apply it 2-3 months prior to planting, ideally incorporated six to eight inches deep.

    Temperature and Microbial Activity

    • Cool temperatures in early spring can inhibit microbial activity.
    • Warmer soil stimulates microbial activity, which is vital for organic fertilizer decomposition and nutrient release.

    Organic Seedling Mixes

    • Organic seedling mixes can be expensive and may have less consistent nutrient delivery than conventional mixes.
    • Add fertilizer once the first set of true leaves appear.
    • Fish emulsion-based fertilizers are commonly used in organic gardening.
    • Organic seedling mixes are made from a mixture of soil, compost, and other ingredients.
    • Different recipes can be found online for organic seedling mix production.

    Weed Control

    • Hand weeding is the oldest and often most effective method for managing weeds.
    • Hand weeding is particularly effective for annual weeds with shallow root systems.
    • Hoeing is a suitable method for removing small weeds or chopping out larger ones, especially in rows with wide spacing between plants.
    • Heavy mechanical cultivation can destroy soil structure and lead to increased breakdown of organic matter which diminishes soil health.
    • Tillage should be performed when soil moisture is adequate, to prevent soil compaction and damage to soil structure.

    Insect Control

    • Strong and healthy plants are more resistant to pests.
    • Nutrient deficiencies and excesses can increase the risk of insect infestations.
    • Soil testing and proper fertility management can help minimize these risks.
    • Beneficial insects can help control pests by preying on them.
    • Creating a habitat for beneficial insects, such as providing overwintering options, can increase their population and reduce pest outbreaks.
    • Manual removal of pests can be effective.
    • Traps can attract and capture pests, but their effectiveness can vary depending on the pest type and trap design.
    • Organic insecticides are derived from botanical or mineral sources.
    • They are typically effective when ingested directly or through contact by the pest.
    • Bacillus thuringiensis (Bt) is an organic insecticide that is effective against caterpillars.

    Crop Rotation and Botanical Families

    • Crop rotation is a crucial practice to maintain soil fertility and prevent pest and disease buildup.
    • Keep detailed records of your garden layout and rotation cycle.
    • Utilizing flash cards with crop names and botanical families can assist in planning a 3-5 year rotation.
    • Examples of crop families and their representative crops include:
      • Solanaceae: Tomato, pepper, potato, eggplant, tomatillo
      • Brassicaceae: Broccoli, cauliflower, cabbage, kale, Brussels sprouts, radish, rutabaga, turnip
      • Cucurbitaceae: Winter squash, summer squash, melons, cucumber, pumpkin
      • Apiaceae: Carrot, parsley, celery, parsnip
      • Chenopodiaceae: Beet, chard, spinach
      • Fabaceae: Pea, bean
      • Asteraceae: Lettuce
      • Liliaceae: Onion, garlic, shallot, leek
      • Poaceae: Corn

    Organic Fertilizer and Nutritional Requirements

    • Organic fertilizers are an environmentally friendly alternative to synthetic fertilizers.
    • Most organic sources require decomposition by soil organisms to release nutrients.
    • Temperature, moisture, and other environmental factors influence decomposition rates.
    • Sources vary in how quickly they release nutrients, with examples including:
      • Slow-release: Soybean meal
      • Medium release: Mushroom compost, sulfate of potash magnesia (K-Mag)
      • Rapid release: Wood ashes, sulfate of potash
    • A soil test provides recommendations for the amount of nitrogen (N), phosphorus (P2O5), and potassium (K2O) required for your garden.
    • Example Calculation:
      • For 1,000 square feet, a soil test recommends 3 lb N, 1.5 lb P2O5, and 4 lb K2O.
      • Using blood meal (12-1.5-0.6) for N, bone meal (1-11-0) for P, and K-Mag (0-0-22) for K, these fertilizer amounts would be needed:
        • Blood meal: 25 lb
        • Bone meal: 10 lb
        • K-Mag: 18 lb

    Soil pH and Liming

    • Optimal pH range for most garden plants is 6.0-6.5.
    • Microbial activity is hindered below a pH of 5.5.
    • Lime is used to increase soil pH and make nutrients more available.

    Organic Pest Control

    • Organic gardening emphasizes cultural, physical, and biological controls to manage pests.
    • The philosophy behind organic pest control involves utilizing "many little hammers" to beat back pests.
    • Cultural controls, the first line of defense, include:
      • Proper plant selection
      • Fertility management
      • Crop rotation
      • Physical exclusion
    • Physical or mechanical controls involve manually removing pests.
    • Biological controls include organic pesticides or beneficial organisms.
    • It is crucial to understand that organic gardening does not prohibit the use of pesticides; it aims for environmentally friendly alternatives.

    Weed Management Techniques

    • Hand weeding is the most effective method for removing annual weeds with shallow roots.
    • Ensure proper timing and consider using tools like hoes for larger weeds.
    • Mulches, plastic, landscape fabric, and cardboard effectively suppress weed growth.
    • Organic matter from mulches enriches the soil.

    Insect Control Strategies

    • Growing healthy plants minimizes insect pressure.
    • Nutrient deficiencies and excesses can attract or exacerbate insects.
    • Soil testing and proper fertility management are key to preventing insect problems.

    Organic Gardening: Soil and Nutrients

    • Organic fertilizers are crucial when transplanting, promoting initial growth.
    • Fish emulsion and liquid organic fertilizers are readily available and effective options.
    • Applying fertilizers weekly for the first two weeks after transplanting ensures sustained growth.
    • Soil blockers are popular tools for organic producers, offering a sustainable alternative to peat pots or seedling flats.
    • Soil blocker recipes vary by producer and typically comprise various organic elements like sphagnum peat, compost, and soil.

    Organic Gardening: Pest Management

    • Beneficial insects play a crucial role in controlling pest populations.
    • Creating a year-round habitat with diverse vegetation encourages beneficial insects to overwinter and thrive.
    • Physical removal of pests by hand is the most reliable and organic method.
    • Using soapy water traps effectively captures and eliminates pests.
    • Organic insecticides offer a sustainable alternative to conventional pesticides.
    • Bacillus thuringiensis (Bt) targets caterpillars and is applied as a spray or powder every 3-5 days.
    • Diatomaceous Earth (DE) is effective against soft-bodied insects and deters beetles and ants.
    • Neem oil, derived from the neem tree, disrupts feeding and development in various insects, particularly aphids, whiteflies, and mealybugs.

    Organic Gardening: Disease Control

    • Properly composting is crucial for organic disease management, including limiting residue from Solanaceous crops.
    • Disease-resistant cultivars offer a proactive approach to disease control.
    • Avoid using treated or genetically modified seeds.
    • Copper-based products are allowed in organic production with restrictions due to potential toxicity.
    • Copper sulfate solutions can be effective against downy mildew, powdery mildew, bean anthracnose, and tomato early blight.
    • Bordeaux mix, a blend of copper sulfate and hydrated lime, is restricted due to its long residual activity and potential harm to bees.
