TL;DR: Evidence that all oxalate-extractable P potentially is desorbable : no irreversibly fixed P OX exists is provided.

TL;DR: In this paper, a comprehensive overview of selected ecosystem services provided by agroforestry with focus on conventional agricultural fields (ACS) in the temperate region is presented, and based on the available data collected, they conclude that ACS are advantageous compared to conventional agriculture in many aspects, and therefore suggest that they should be implemented at a larger scale in temperate regions.

TL;DR: In this article, a literature survey was undertaken to provide an overview of the different ecological benefits arising from alley cropping systems within temperate Europe, and the results showed that alley croppers may be an ecologically advantageous land use system for sustainable food and biomass production in comparison with conventional agricultural practices.

TL;DR: In this paper, the authors measured topsoil and subsoil samples from different soils located in the eastern part of Germany and found that the total P sorption was predominantly related to the amounts of amorphous iron (Feox) and aluminium (Alox).

TL;DR: In this paper, the authors combined scientific and technical knowledge to evaluate nine environmental pressures in terms of ecosystem services in European farmland and assessed the carbon storage potential of suitable agroforestry systems, proposed by regional experts.
