A rural property may look suitable for a specialist crop, but visual impressions are not enough. This anonymised case study shows how soil analysis, site conditions, water availability and access were brought together to assess the feasibility of a white truffle plantation in Sardinia.
The client’s objective
International buyers were evaluating a large rural holding in central Sardinia as the basis for a long-term agricultural project. One of the main options was a plantation for Tuber borchii, the bianchetto or whitish truffle.
What had to be verified
- soil texture and drainage;
- pH and limestone content;
- exchangeable calcium and other chemical characteristics;
- altitude, exposure and local climate;
- water availability and irrigation potential;
- road access and internal logistics;
- utilities and the practical conditions for developing the holding.
Soil sampling and laboratory results
Representative soil samples were collected and analysed by a specialist laboratory. The results indicated a sandy-loam texture, a favourable pH, good exchangeable calcium and very low total and active limestone. These findings were interpreted together with the physical characteristics of the site rather than considered in isolation.
The technical conclusion
The combined assessment confirmed that the selected areas offered suitable conditions for a Tuber borchii project, subject to correct planting design, certified mycorrhizal plants, irrigation planning and appropriate management during establishment.
The study also distinguished between the property’s theoretical agricultural potential and the practical requirements of implementation. This allowed the buyers to understand what could realistically be developed, which investigations were already sufficient and which decisions would still be needed before investment.
What the clients received
- review of the available property and site information;
- field inspection and selection of sampling areas;
- coordination of specialist soil analyses;
- agronomic interpretation of laboratory results;
- assessment of water, access and infrastructure;
- a clear feasibility conclusion and recommendations for the operational phase.
Why this approach matters for foreign investors
Specialist agricultural projects require more than finding land advertised as fertile or suitable. An independent feasibility study helps foreign buyers test an idea before committing further capital and identifies the technical conditions that must be incorporated into the project from the beginning.
This real case study has been anonymised to protect the clients’ privacy. Their names, the municipality and the exact property location have therefore been omitted.
Considering a truffle plantation in Sardinia?
I can assess the land, coordinate soil sampling and laboratory analysis, and explain whether the proposed investment is technically realistic before you proceed.
