Q

SITE SELECTION (8)

A
  1. Soil
  2. Freedom from weeds
  3. EXPOSURE and ASPECT
  4. SLOPE
  5. WATER
  6. SIZE of the AREA
  7. GROUND COVER
  8. SOURCE OF LABOR
27
Q

Soil (4)

A
  1. Physical, chemical and biological properties to be considered
  2. Soil texture (light sandy loam or loamy sand)
  3. Soil pH
  4. Soil fertility
28
Q

SITE SELECTION:
Freedom from weeds (1)

A

Free from annual and perennial weeds

29
Q

SITE SELECTION:
EXPOSURE and ASPECT (4)

A
  1. Open as possible
  2. Not exposed to strong winds
  3. East, northeastern facing slopes which are colder
  4. Consider orientation of nursery beds; nursery beds are to be parallel to the NE direction
30
Q

SITE SELECTION:
SLOPE (2)

A
  1. Flat areas not desirable; 3-5% slope is desirable so that rainwater will not stagnate, and distribution of water can be facilitated through gravity
  2. If too steep, do bench terracing
31
Q

SITE SELECTION:
WATER (3)

A
  1. Quantity and quality
    considerations
  2. Water pH
  3. Water source
32
Q

SITE SELECTION:
SIZE of the AREA (1)

A
  • Wide enough to accommodate all essential parts of the nursery and supportive infrastructures
33
Q

SITE SELECTION:
GROUND COVER

A
  1. Least cost for site preparation activities
  2. Soil fertility and soil moisture regime
34
Q

SITE SELECTION:
SOURCE OF LABOR (3)

A
  1. Labor intensive
  2. Close to source of abundant cheap labor
  3. Social desirability
35
Q

DESIGN AND LAY-OUT (4)

A
  1. Should mimic a factory
  2. Requires a knowledge of the whole process
    of seedling production
  3. Takes into consideration all the activities
    and required facilities
  4. Should allow for economical movement of
    people and materials
36
Q

DESIGN AND LAY-OUT:
PARTS OF A FOREST NURSERY (2)

A

Production
Non-production

37
Q

DESIGN AND LAY-OUT:
directly related to the nursery seedling culture

A

Production

38
Q

DESIGN AND LAY-OUT:
non-direct but critical in the production of seedling stocks

A

Non-production

39
Q

DESIGN AND LAY-OUT:
PRODUCTION AREA (8)

A
  1. Nursery beds
  2. Seed house
  3. Soil shed/storage
  4. Potting shed
  5. Compost compartment
  6. Seedling processing shed
  7. Tool room/chemical storage
  8. Water impoundment area
40
Q

DESIGN AND LAY-OUT:
NON-PRODUCTION AREA (4)

A
  1. Nursery office
  2. Laborers’ quarters
  3. Motor pool
  4. Other infrastuctures in support of seedling production
41
Q

DESIGN AND LAY-OUT:
The Road System (4)

A
  1. Interior roads should be enough to permit turning space for vehicles
  2. Perimeter road for security reasons
  3. Surfacing with fine rocks or gravel
  4. Paths will also be necessary
42
Q

DESIGN AND LAY-OUT:
WATER SUPPLY/IRRIGATION SYSTEMS (#1 (2))

A

From the source (impoundment system)
1.Gravity system
2.Pumps

43
Q

DESIGN AND LAY-OUT:
WATER SUPPLY/IRRIGATION SYSTEMS (#2 (3))

A

Distribution within the nursery
1.Open ditches
2.Surface pipes
3.Underground pipes

44
Q

DESIGN AND LAY-OUT:
Watering the Nursery Beds (4)

A
  1. Sprinkling
  2. Flooding
  3. Furrow irrigation
  4. Drip irrigation or sub-irrigation
45
Q

FOREST NURSERY PRODUCTION SYSTEMS:
Containerized Production Systems (5)

A
  1. Potted
  2. Tube
  3. Sets
  4. Striplings
  5. wildlings
46
Q

FOREST NURSERY PRODUCTION SYSTEMS:
Bareroot Production Systems (3)

A
  1. Bareroot
  2. Stumps
  3. Balled planting stocks
47
Q

FOREST NURSERY PRODUCTION SYSTEMS:
Advantages of BAREROOT (6)

A

▪ minimal transplanting
▪ easier tending
▪ lesser weight during transport
▪ simple processing and handling of planting stocks
▪ best suited for mechanized planting

48
Q

FOREST NURSERY PRODUCTION SYSTEMS:
Disadvantages of BAREROOT (5)

A

▪ need for excellent nursery soil
▪ longer sowing synchronization time
▪ greater risk of root damage
▪ needs abundant water during nursery seedling culture
▪ non-flexibility of planting dates

49
Q

FOREST NURSERY PRODUCTION SYSTEMS:
ADVANTAGES of CONTAINERIZED (6)

A

▪ no need for good nursery soil
▪ shorter production time
▪ root integrity preserved
▪ faster growth initiation after outplanting
▪ planting season can be extended
▪ minimal start-up time

50
