3. Pillar 1: Promote sustainable management of soil
resources for soil protection, conservation and
sustainable productivity
• Soil is a flagship research and development issue in the Pacific
Islands
• Supported Fiji’s UNCCD and FAO funded land degradation neutrality
project
• In promoting the voluntary guidelines for sustainable soil management
- PSP is promoting use of targeted compost on atolls and use of
Mucuna pruriens as cover crop in higher islands.
• Best management in national priorities:
• A focus on managing the hydraulic behaviour of NZ soils
• SSM reducing sediment, nutrients and pesticides reaching the Great
Barrier Reef
• New national landscape program in Australia focussed on key soil
management issues
• New interest by financial companies in ‘natural capital’
4. Pillar 2: Encourage Investment, Technical
Cooperation, Policy, Education, Awareness and
Extension
• Pacific island nations:
• Soil science in the capacity building component of the Pacific
Regional Extension Plan (Tonga, Fiji and Kribati)
• Aim for national education systems to incorporate soil science
into their school curricula.
• Soil doctor program in Tonga, Kiribati, Tuvalu, Marshall Islands
and Fiji (Hanna quick soil test kits, Solvita respiration tests, and
the Palintest SKW 500 soil test kit).
• Australia: A focus of state agencies and Soil Science
Australia
• Soil Security and Planetary Health Conference – Sydney,
4-6 December 2018
5. Pillar 3: Promote targeted soil research and
development focusing on identified gaps,
priorities and synergies with related productive,
environmental and social development action
• ACIAR/FAO support atoll soil health research in the Pacific
Islands
• New ACIAR Project Soil management in the Pacific Islands:
Investigating Nutrient Cycling and Development of a Soil Portal
is going to use the concept of mass nutrient balance to guide
nutrient cycling and management and also set up a Pacific Soil
Portal.
• Soil and water management promoted under Climate Smart
Agriculture initiatives in the Pacific Islands
• New momentum in soil carbon R&D in New Zealand
• Renewed interest in SOM dynamics, soil water and irrigation
strategies and removing sub-soil constraints

Targeted Compost on Atolls
9. Pillar 4: Enhance the quantity and quality of soil
data and information: data collection
(generation), analysis, validation, reporting,
monitoring and integration with other disciplines
• The ACIAR Project will develop a soil portal for the islands
• Will work with Pacific Islands Rural Advisory Services linking the
crop management practices to soil information.
• Soil and Landscape Grid of Australia
• New Zealand
• New Zealand National Soil Data Repository with substantial
functionality
• S-Map
10. Pillar 5: Harmonization of methods,
measurements and indicators for the sustainable
management and protection of soil resources
• The ACIAR Project will:
develop well evaluated and calibrated soil tests for the
different soils in the region.
develop an appropriate soil test for organic carbon for atolls
in the region.
• PSP will revive the South Pacific Agricultural Laboratory Network
(SPACNET) under the new ACIAR Project
• Soil information inter-operability across the region using
ANZSOILML
11. COP 23 Presidency of Fiji
• Supported preparation for COP 23 by presenting a technical paper to
Pacific Leaders in the Pre COP meeting July 2017 on Climate Smart
Agriculture: Nutrient and Carbon Smart Technologies
• Supported Tongan Government’s side event on Plant Health and
Climate Change at the COP 23 in Bonn with a presentation on Climate
Smart Agriculture.
In addition:
• CSA, soils and water research priorities for the Pacific Region - side
event at the Pacific Agricultural Week to be held in Vanuatu, October
2018.
• Two climate smart villages in Tonga, Kiribati, Marshall Islands and
Tuvalu.
• Supported the Indian Soil Partnership in the running of an
international conference on food and sustainable agriculture held in
Dhanbad, Jharkhand from 27th to 30th March 2018. The PSP member
delivered the key note address for climate smart agriculture.
12. S-map
Prime Goals
One complete soil map for NZ
Upgrade good data + fill gaps
Best available mapping/modelling
techniques
Quantitative information for every soil
Customised outputs
Support management at all scales
13. NZ and soil carbon
• data requirements for greater inclusion of soil carbon in
the national greenhouse gas inventory:
• New sampling strategies across various environmental factors
(such as farm management, irrigation, soil type, climate and
topography)
• A long-term plan for implementing these strategies is being
developed.
• New Zealand’s soil carbon stocks are relatively high –
and that soil carbon stocks are higher under pasture,
when compared to forests.
• New Zealand’s hill country pasture is gaining soil
carbon, while our flat land pasture may be losing soil
carbon.
16. The new ACIAR soil information system
• Answer key questions at the
regional scale
• Are nutrient budgets of Pacific Islands
sustainable?
• Can routine soil testing be delivered to
all countries?
• Can appropriate fertilizers and
ameliorants be delivered to the right
places at the right times?
• Mechanism of technical support for
lower-income countries in the
Pacific
• Technical teams take advantage of
proximity
• Improve delivery to the global
system

Editor's Notes
Project analysed different nutrient sources. Now have a list of sources high in different nutrients (yellow box) and best bets for targeted composting.
This is a result from a compost recipe in MarshalL Islands showing how compost targeting s=nutrient limitations has increased taro yields. Rates were no compost, 1 shovel, 2 shovels, and 3 shovels per planting hole.
Data shows N-fixation, amount of P mobilized by mucuna and a f-fractionation result showing mucuna mobilized Fe and Al P. Bottom left graph shows how mucuna and fertlizers (treatment b) improved yield. The other 2 graphs are self explanatory – mucuna fallow better than grass fallow. And mucuna in general better in labile C.
