Study Notes
Nursery Establishment
Overview
- A forestry nursery is a specialized facility for growing tree seedlings and saplings
- Purpose: to produce high-quality planting stock for reforestation, afforestation, and woodlot establishment
Site Selection
- Criteria for selecting a nursery site:
- Accessibility
- Climate and soil suitability
- Water availability
- Topography and drainage
- Proximity to seed sources and planting areas
Nursery Design and Layout
- General layout:
- Seedling production areas
- Seed storage and processing areas
- Irrigation and water management systems
- Access roads and paths
- Bed layout and spacing:
- Typically 1-2 meters between beds
- 10-30 cm between seedlings
- Orientation to maximize sunlight and air circulation
Seed Collection and Handling
- Seed collection:
- From mature trees or seed orchards
- Methods: manual, mechanical, or through seed traps
- Seed processing:
- Cleaning and grading
- Treatment with fungicides and insecticides
- Storage in cool, dry conditions
Sowing and Planting
- Seed sowing:
- In seed trays or directly into beds
- Depth and spacing dependent on species
- Planting:
- Seedlings typically transplanted at 1-2 years old
- Hand-planting or machine-planting methods
Irrigation and Water Management
- Importance of adequate water supply:
- Seedlings require consistent moisture, especially during establishment
- Irrigation systems:
- Overhead sprinklers
- Drip irrigation
- Flood irrigation
- Water management strategies:
- Mulching to reduce evaporation
- Cover cropping to reduce soil moisture loss
Pest and Disease Management
- Common pests and diseases in nurseries:
- Insects (e.g., aphids, whiteflies)
- Fungal diseases (e.g., root rot, leaf spot)
- Bacterial diseases (e.g., crown gall)
- Integrated pest management (IPM) strategies:
- Cultural controls (e.g., sanitation, pruning)
- Biological controls (e.g., beneficial insects)
- Chemical controls (e.g., pesticides, fungicides)
Record Keeping and Quality Control
- Importance of accurate record keeping:
- Tracking seed sources, sowing dates, and planting stock performance
- Monitoring nursery conditions and pest/disease issues
- Quality control measures:
- Regular inspections and evaluation of seedlings
- Implementation of standard operating procedures (SOPs)
Nursery Establishment
Overview
- A forestry nursery is a specialized facility for growing tree seedlings and saplings to produce high-quality planting stock for reforestation, afforestation, and woodlot establishment.
Site Selection
- Accessibility is a key criterion for selecting a nursery site.
- Climate and soil suitability are critical factors in nursery site selection.
- Water availability is essential for nursery operations.
- Topography and drainage must be considered to prevent waterlogged soil.
- Proximity to seed sources and planting areas is important for efficient operation.
Nursery Design and Layout
- A general nursery layout includes seedling production areas, seed storage and processing areas, irrigation and water management systems, and access roads and paths.
- Bed layout and spacing typically range from 1-2 meters between beds and 10-30 cm between seedlings.
- Bed orientation should maximize sunlight and air circulation.
Seed Collection and Handling
- Seeds are collected from mature trees or seed orchards using manual, mechanical, or seed trap methods.
- Seed processing involves cleaning, grading, and treating with fungicides and insecticides.
- Seeds are stored in cool, dry conditions to preserve viability.
Sowing and Planting
- Seeds are sown in seed trays or directly into beds, with depth and spacing dependent on species.
- Seedlings are typically transplanted at 1-2 years old using hand-planting or machine-planting methods.
Irrigation and Water Management
- Adequate water supply is crucial, as seedlings require consistent moisture during establishment.
- Irrigation systems include overhead sprinklers, drip irrigation, and flood irrigation.
- Water management strategies include mulching to reduce evaporation and cover cropping to reduce soil moisture loss.

- Common pests and diseases in nurseries include insects, fungal diseases, and bacterial diseases.
- Integrated pest management (IPM) strategies include cultural controls, biological controls, and chemical controls.
Record Keeping and Quality Control
- Accurate record keeping is essential for tracking seed sources, sowing dates, and planting stock performance.
- Quality control measures include regular inspections and evaluation of seedlings, and implementation of standard operating procedures (SOPs).
