PARAMETERS
USE OF GIS/GPS + DRONES
Most companies have purchased the equipment but not fully utilized
More on-the-ground inputs are required to formulate the design incorporating:
Road design
Types of terraces
Drainage design for water management

CURRENT INDUSTRY ISSUES
Yield stagnation
Mechanization

REASON FOR YIELD STAGNATION
LOW PLANTING DENSITY
![Page 7: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/7.jpg)

MAXIMIZING THE PLANTING DENSITY
Despite availability of the Violle and Constant Planting Density techniques,
how many plantation companies:
Are aware of their existence?
Are implementing them?
Have revised their SOPs to adopt the systems?
![Page 8: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/8.jpg)

Planting density will be determined by:
Road design and density
Terrace density
Planting distances
Maximum land utilization

IMPACT ON LOW PLANTING DENSITY
At 98 palms/ha, loss of 32 palms/ha = 25% of yield potential.
Taking average yield of 22 mt/ha, the loss will be 5.5 mt/ha x 5,000ha = 27,500 mt/year x 23 years = 632,500 mt x RM500/mt FFB = RM316.25 million or RM2,750/ha/year !!!!!!!!!
MAXIMIZING THE PLANTING DENSITY

MAXIMIZING THE PLANTING DENSITY
What had caused the blunder?
Poor road design = higher road density
Lower terrace density
Use of standard distance at 8.5m apart irrespective of the terrace distances!
Lining done by contractors
LACK OF KNOWLEDGE
REFUSAL TO CHANGE - COMPLACENT

the slope:
Double terraces : 6° - 15°
Single terraces : 16° - 25°

20
DOUBLE TERRACES
Advantages:
a) Minimum disturbance to soil structure
b) Minimum surface/lateral erosion
c) Better moisture conservation
d) Early mechanized / semi-mechanized operations
e) More efficient supervision (from excellent access)
![Page 21: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/21.jpg)
21
SINGLE TERRACES
Now constructed wider between 4.0 – 5.0m for
eventual mechanization
Disadvantage
a)Early semi-mechanized operations not possible
due to frond interference
![Page 22: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/22.jpg)

GIS / GPS
Most useful in the initial planning
Useful to determine the final planting density (tree count)
Not fully utilised
![Page 23: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/23.jpg)
23
CONSTANT PLANTING DENSITY
A modified version of the Violle system.
How the system works
Measure average terrace distances using Tru Pulse ( a digital equipment)
Record each distance on Field Inventory pegs for each terrace
Use table to determine the planting distances
Each planting distance recorded of the Field Inventory peg

MECHANICAL HOLING
Disadvantages of manual holing:
a) Not uniform
b)Inadequate depth – restricts root development
c) Where is the labour?
d) Where is the work quality?
e) Low productivity
![Page 26: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/26.jpg)
26
MECHANICAL HOLING
Disadvantages of mechanical auger
a) Cementing of the edges of the holes –
will impede good early root development
b) Same sub-soil used in the planting hole
![Page 27: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/27.jpg)
27
MECHANICAL HOLING - BIG HOLE
Advantages:
a) Bigger hole
b) Filling with good top soils = better root development = better growth = higher yield
c) Better moisture retention
d) Excavated soils utilized as stop bunds to minimize lateral erosion
e) Same excavator can be utilized simultaneously to repair terraces

Objectives
To maximise land use : 0-wastage
To increase planting density
MAXIMIZING LAND UTILIZATION
![Page 42: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/42.jpg)

MAXIMIZING LAND UTILIZATION
APPROACH
“Zip system” i.e. construction of raised
platforms which are connected to elevated
paths.

ZIP SYSTEM
ADVANTAGES
Palms above water during flash floods
Minimizes fertilizer wash off
Good palm-to-palm and palm-to-road access
Mechanised operations
Efficient supervision

WHY MECHANIZE?
Current status: Acute shortage of workers Rising costs Will worsen in future
![Page 47: FINE-TUNING OF FIELD DESIGN DURING REPLANTING … · · 2017-07-18POTENTIAL AND MECHANISED OPERATIONS : HOLISTIC CONSIDERATIONS 1 ... From the Initial Model Newplanting in MPOB,](https://reader031.vdocuments.net/reader031/viewer/2022020412/5ad454d97f8b9a571e8c1292/html5/thumbnails/47.jpg)
47
WHY MECHANIZE? Reasons for labour shortage
“Yo-yo” Government policies on recruitment of foreign workers.
Huge opportunities in Indonesia. No reason to come to Malaysia.
Comparable earnings in Indonesia.
Very low Malaysian Ringgit divert workers to work in other countries e.g. Saudi Arabia.
Continued indifferent attitude of Malaysians to work in plantations.

WHY MECHANIZE?
Questions to ponder:
* What will be the scenario in 5-10
years time?
* How serious are plantation
companies in over coming the
worsening situation?

MECHANIZATION
Types of operations which can be mechanized
Mechanical holing (big-hole)
Distribution of seedlings direct to planting points
– 0- casualty achieved in MKIC estates
Semi-mechanized fertilizer applications
Semi-mechanized P&D work
Semi-mechanized weeding work

MECHANIZATION
Land Preparations
Mechanization never done “impromptu”
Requires vision and meticulous planning in form
of:
Construction of elevated paths
Construction of double-terraces
Construction of wider single terraces
Implementing “zip” system

LABOUR : LAND RATIO Improved Labour: Land Ratio
Example on 1,800ha estate:
100% manual operations @ 1:10ha = 180 workers
70% mechanized operations @ 1:25ha = 50 workers
Balance 30% @ 1:10ha = 54 workers
Total labour requirement = 104 workers
Reduction = 76 workers or 42%

Notes:
Although conventional replanting is cheaper by 47% but it has the following limitations:, it has the following limitations:
* Higher risks on future Ganoderma infection - loss of potential yield
* Not prepared for eventual mechanization - higher manual labour requirement = higher production costs
* Loss of potential yield from flooding in low-lying areas
* Cost difference between construction of double and single terraces is only 15% but the benefits are many
