Soil phosphorus availability as an indicator of forest productivity in Pinus halepensis Mill. plantations. Relationship between P pools and soil properties.
The main objective of this master's thesis is to assess the state and availability of phosphorus (P) in limestone soils in northern Spain. To do this, we studied the organic and inorganic extractable P fractions as well as the more stable ones that are usually more abundant in limestone soils....

| Sumario: | The main objective of this master's thesis is to assess the state and availability of phosphorus (P) in limestone soils in northern Spain. To do this, we studied the organic and inorganic extractable P fractions as well as the more stable ones that are usually more abundant in limestone soils. We tried to uncover which soil properties determine the edaphic P availability and state in Pinus halepensis Mill. plantations and we studied whether the P availability affects the productivity of these forests. This research has been developed using part of the soil samples taken during the Ph.D. thesis of Dr. Teresa de los Bueis Mellado, co-tutor of this work, titled: “Relationships between the dynamics of Pinus halepensis Mill. and Pinus sylvestris L. plantations and environmental parameters: a basis for sustainable management of stands” defended in 2017. For this reason, the physiographic, climatic and stand data, as well as various soil parameters, have been obtained from this previous doctoral thesis. The author of this master's thesis carried out the laboratory analysis for the determination of soil phosphorus and the statistical study necessary to achieve the objectives of this work. |
