Phytosiderophores released by graminaceous species promote 59 Fe uptake in citrus
(Springer Verlag (Germany), 2006)Chlorosis-susceptible fruit trees growing on calcareous soils have been observed to recover in the presence of grass cover species. However, the physiological mechanisms behind this phenomenon are only scarcely understood. ... -
On the qualitative analysis of the solutions of a mathematical model of social dynamics
(Elsevier, 2006)This work deals with a family of dynamical systems which were introduced in [M.L. Bertotti, M. Delitala, From discrete kinetic and stochastic game theory to modelling complex systems in applied sciences, Math. Models Methods ... -
An approach to the identification of indicators for forest biodiversity – the Solling mountains (NW Germany) as an example
(Wiley-Blackwell, 2006)In this study, we present an approach for the identification of indicators for biodiversity within forest ecosystems. We analyze the data of stands of pure Norway spruce (Picea abies (L.) Karst) and European beech (Fagus ... -
Iron nutrition of fruit tree crops
(Springer, 2006)Although iron (Fe) needs by fruit trees are relatively low, Fe deficiency represents the main constraint for successful cultivation of fruit tree crops in calcareous and alkaline soils. Kiwifruit, peach and pear, several ... -

Soil nitrogen leaching from tree row strips and grassed alleys in a pear orchard
(Plant Research International, 2006)A study was carried out to evaluate nitrogen losses between October 2004 and February 2005 in a pear (Pyrus communis cv. Abbé Fètel) orchard, in the eastern Po Valley (Northern Italy). NO3 - concentration was determined ... -
