Black Truffle Farming: What a Plantation Costs and Yields

Truffle farming is agriculture with a ten-year horizon: you plant an inoculated tree, you spend a decade looking after it, and only then does the plantation start to pay.

This article puts the grower’s own numbers on the table: what a plantation costs, when it earns, what a hectare yields and who actually does this work.

None of it is a promise. All of it is what he says out loud when someone asks him whether to plant.

What it costs to plant: the grower’s example

Asked what a plantation costs, the grower gives a practical case: ten hectares planted this year, on land the owner already has and with the owner’s own machinery, comes to around 200,000 euros. His first figure was 150,000 to 200,000, and he settled on the higher end because materials have become much more expensive.

That is the answer to “how much does truffle farming cost?” without inventing anything: about 20,000 euros per hectare with land and machinery already in hand.

When a truffle farm earns money

The timeline is the most valuable thing the grower says, and he does not soften it. First truffles at five or six years, in token amounts. Commercial production from eight to ten.

The plantation does not just recover its investment but starts to earn from ten to twelve years. Peak production runs from twelve to about eighteen, and a tree keeps producing until roughly thirty. In his words: a very long-term investment.

The three yield scenarios

The grower designs his plantations to produce as much as possible, aiming at 300 kilos per hectare. Being realistic, he corrects himself at once: 200, 250. That is a design target.

What he calls ideal in practice is 50 kilos per hectare. And producing anything from 20 kilos upward is already, in his view, a good result.

A business plan for a truffle farm should be built on the second and third numbers, not the first.

• Design target: 200–250 kg per hectare.
• Ideal in practice: 50 kg per hectare.
• Already a good result: 20 kg per hectare and up.

Density, and what it means for the order

The grower plants 300 trees per hectare. Forty hectares is about 12,000 plants, which is his own arithmetic for a large project.

That number drives the plant order, the nursery lead time and a large share of the initial cost.

Subsidies come and go

In Castilla-La Mancha, the last subsidy for truffle plantations came out in 2021 and, by the grower’s account, could have covered around three quarters of a project like the ten-hectare example. Reforestation aid runs at 70 to 80 per cent.

His practical warning: when such a subsidy opens, the decree can oblige the buyer to source the plant within the region. Waiting for the next one is a strategy with no date attached.

Who does this work, and how few are trained

The sector, the grower says, has very little generational renewal and little professionalisation. He himself has spent thousands of euros on training over the years, which few farmers do.

The reference course in Spain, four or five days of establishment training, takes around 16 people a year in the whole country, at two to three thousand euros per person. Nobody arrives from zero and becomes a farmer tomorrow.

Truffle farming in the southern hemisphere

Truffle farming has spread to the southern hemisphere, in counter-season. The grower reports, from data he says he has not seen in person, that the largest productions today are in Australia and New Zealand, with some plots around 300 to 400 kilos.

He passes that on with his own reservation, and so does this page.

Where a truffle farm starts

It starts with the plant. The page on truffle trees explains where it comes from, how a nursery proves the inoculation and how the order is sized by surface.
