Soil fertility status of stone pine (Pinus pinea) stands in Portugal
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...
