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

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...

Manual cone harvesting of Pinus pinea in Portugal: equipment used and recommendations

Iron tips used to detached the cones from the tree (A), toothed hook of the iron ladder (B); module extension of the iron ladder (C)

Stone pine (Pinus pinea L.) cone harvesting in Portugal continues to occur trough the traditional way, that is, by specialized workers that climb the trees and remove the cones by hand using special tools.

Here we intend to document photographically this traditional knowledge, present  the various tools used by cone pickers in the harvesting process and the materials used to build them. This information can be potentialy usefull in other coutries were cone harvesting is made by small, locally operating family firms.

Pine cone quality assessment with X-Ray

Inshell pine nuts X-rayed (Pinus pinea)

The objective is to analyze the possibility of modeling the kernel weight from biometric and morphological parameters of the pine nuts from Pinus pinea, measured through X – ray and image analysis. The overall objective is to support the definition of a pine cone quality assessment methodology at the stand/ farm level in order to provide the landowners with tools for pine cone commercialization and increase by this mean the market transparency.
