Processes governing phosphorus availability in temperate soils
Phosphorus losses from agricultural soil to water bodies are mainly related to the excessive accumulation of available P in soil as a result of long-term inputs of fertilizer P. Since P is a
Diversity and structure of AMF communities as affected by tillage in a temperate soil
TLDR
The community structure of AMF in the field soil was significantly affected by tillage treatment, however, no significant differences in AMF diversity were detected among different soil tillage treatments and the use of trap cultures for fungal diversity estimation in comparison with direct observation of field samples is discussed.
Potential for increasing the content and bioavailability of Fe, Zn and Ca in plants for human nutrition.
TLDR
The possibility and limits for increasing the content and bioavailability of iron, zinc and Ca in edible parts of staple crops, such as cereals, pulses, roots and tubers as a way to combat mineral deficiencies in human populations are reviewed.
SOIL TILLAGE AFFECTS THE COMMUNITY STRUCTURE OF MYCORRHIZAL FUNGI IN MAIZE ROOTS
TLDR
Whether communities of arbuscular mycorrhizal fungi colonizing the roots of maize were affected by soil tillage practices in a long-term field experiment carried out in Tanikon (Switzerland) is tested.
Low-P tolerance by maize (Zea mays L.) genotypes: Significance of root growth, and organic acids and acid phosphatase root exudation
TLDR
The study found increased root development and increased exudation of acid phosphatase under P-deficient conditions in all maize genotypes, except for the Swiss cultivar, which was compared with a Swiss commercial cultivar.
Chemical nature of organic phosphorus in cultivated and uncultivated soils under different environmental conditions
SUMMARY A sequential alkali extraction procedure followed by ultrafiltration and quantitative 31P nuclear magnetic resonance (NMR) spectroscopy was used to examine organic phosphorus in a Brown
Intra- and intersporal diversity of ITS rDNA sequences in Glomus intraradices assessed by cloning and sequencing, and by SSCP analysis
TLDR
The level of molecular variability in the arbuscular mycorrhizal fungus (AMF) Glomus intraradices was assessed, and no evidence for genetic exchange was found on the interspecific or intergeneric level.
Strong mixture effects among four species in fertilized agricultural grassland led to persistent and consistent transgressive overyielding
TLDR
Performance better than monocultures can be achieved with grass–legume mixtures that have a low number of species, across a wide range of species proportions and in nutrient-rich conditions, suggesting a highly increased resource-use efficiency in mixtures.
