Natural pastures, which are the main source, could be improved by using a proper fertilization, among other practices. With the aim of evaluating the effect of different fertilizers on biomass production and sev- eral nutritive value parameters (crude protein, fiber and lignin) of the pasture in comparison with the traditionally used superphosphate, a study was initiated in 2006/07. In the present communication, the third-year-results (2008/09) are presented. The study was carried out in a dehesa located in Extre- madura, in two areas: one with natural pastures and other with sown pastures. Eight surface-broadcast fertilization treatments were done in autumn. Two grazing periods were simulated by cutting the pas- ture in middle-spring and late-spring. Although no statistical differences were found among treat- ments, fertilizers tended to increase biomass production in comparison to the non-fertilized control; in some cases (treatment M1in the sown pasture) increments were close to 50%. Regarding the nutritive value, treatment T2 (the highest doses of Thomaskali fertilizer, 300 kg·ha-1) produced biomass with the significant highest protein content</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: PASTOS: FUENTE NATURAL DE ENERGÍA 4ª Reunión Ibérica de Pastos y Forrajes&lt;br/&gt;pub-location: Zamora</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">GARCÍA MORENO, A.

In October 2007, 126 leaf samples were collected from trees in nine different dehesa farms. These leaf samples were analyzed by means of conventional chemical methods to get macronutrients contents (N, P, K, Ca, Mg) and micronutrients contents (B, Cu, Fe, Mn, Zn). In addi- tion, acorn production and tree health (measured by defoliation rate) were estimated in each tree. The results show that the nutritional state of holm oak in dehesas gets acceptable levels. There are correla- tions between health tree and some nutrients (P, Mg and Mn), moreover, there are correlations be- tween K content and acorn production, and K content and relative water content of the leaf.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: PASTOS: FUENTE NATURAL DE ENERGÍA 4ª Reunión Ibérica de Pastos y Forrajes&lt;br/&gt;pub-location: Zamora</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Benavides, R.</style></author><author><style face="normal" font="default" size="100%">ROIG, S.</style></author><author><style face="normal" font="default" size="100%">Ponce, R.

However, this is a complex task due to the large number of influencing factors and the characteristic diversity and heterogeneity of this production. The objective of this work is to analyze and model the pasture production in a dehesa of Central Spain. The study site is located in the Dehesón del Encinar (Toledo) state, in a low density dehesa (17 trees/ha). A first geostatistical approximation is used with data from two contrasted sampling years: 2008 and 2009. Sampling data include zones under tree influence and pasture without any canopy cover. Geostatistical techniques and GIS result to be efficient tools for analyzing and predicting pas- ture production as well as for agroforestry systems management.
