Impact of irrigation and fertilization on Black truffle (T. melanosporum) fructification

Submitted by MAROIS Olivia on 20 September 2019

The environmental factors that play a role in the fructification of black truffle are well known. In particular, low water availability during summer period inhibits fruiting. These elements result from observations and tests under controlled conditions. At the time of the study (late 1970s), there was no field trial to determine experimentally the influence of environmental factors in cultivated truffle conditions. A trial on a truffle farm located in south-eastern France was therefore set up in 1979 to clarify the influence of soil fertility and moisture levels on Black truffle...

Fertilizer aplication in a stone pine stand experimental trial

Rational fertilization can improve tree health, growth and potentially benefit pine cone and pine nut production. The reduction of forest exploitation costs without neglecting environmental factors and promoting biodiversity is an important management achievement in the context of climate change.

To establish fertilizer recommendations in stone pine for cone production, it is crucial to evaluate soil fertility, tree nutritional status and, if irrigated, the quality of the irrigation water. Here we present part of the results of the operational group FERTIPINEA, focused on the...
