Soil preparation to Creating a Truffle Plantation

The truffle is a fungus which has a symbiotic relationship with the roots of certain trees like the oak or the hazel. It is therefore very important to encourage the root development of these trees by some serious soil preparation before planting.

Truffle Plantation

If you want to plant just a few truffle plants, the classic soil preparation techniques will suffice.

See soil preparation.

If you are looking to create a large truffle producing area, then you will have to resort to using some farm machinery. The aim of the soil preparation is to improve drainage and thus promote the best rooting of the plants. The soil will need to be worked deeply whatever the case. The use of a soil ripper for breaking up the soil should be considered if the soil has not been worked for several years.

Truffle Plantation

To increase the yield, certain chemical elements in the soil may need to be adjusted:

- pH of the soil: add crushed lime or dolomite if the soil lacks magnesium. Liming should only be undertaken if the soil contains a lot of organic matter, which the lime would break down.

- Organic matter and mineral content (level of carbon /nitrogen):

If C/N < 9 : add organic matter rich in carbon (such as maize husks).
If C/N > 12 : add ammonium nitrate, organic matter should not be dug in.

Remember not to add compost or peat to your soil.
You will end up making it more acidic and kill off the mycelium.
