Climate change poses direct or indirect influences on physiological mechanisms in plants. In particular, long living plants like trees have to cope with the predicted climate changes (i.e. drought and air warming) during their life span. The present study aimed to quantify the consequences of simulated climate change for foliar N metabolites over a drought-rewetting-drought course. Saplings of ...

In a 3-year lysimeter experiment we investigated how young trees of Quercus robur, Q. petraea and Q. pubescens, growing either on acidic loamy sand or calcareous sandy loam, responded to an elevation in air temperature by 1-2°C and drought periods lasting several weeks. As intended, the water potentials were clearly lower in drought-treated soil than in the control treatment. Decreased evapotra...

This study compares the effectiveness of multi-micronutrient formulations containing iron (Fe), manganese (Mn), and zinc (Zn) with traditional (EDTA, DTPA, HEEDTA, and EDDHAm) or novel chelates (o,p-EDDHA, S,S-EDDS, and IDHA) and natural complexing agents (gluconate and lignosulfonate). The stability and reactivity of the formulations were studied on batch experiments with calcareous soil and b...

ABSTRACT- The present research was conducted to study K forms and fixation in soils of southern Iran (Hormozgan Province) with aridic and aridic-ustic regimes and to address the relations between soil mineralogy and potassium forms. Thirteen surface soil samples (0-25 cm) were collected from different regions and analyzed in laboratory. Illite and feldspar and mica are the major clay and soil m...

in calcareous soils with high calcium carbonate contents and ph, the growth and development of plant might undergo nutritional disorders. the process of biological nitrogen fixation in legumes cultivated and plant growth in these soils could be limite. the use of acid-producing materials like sulfur and a reduction in soil ph improves plant growth and increase the biological nitrogen fixation. ...

A clear understanding of the impacts of forest practices on long-term soil productivity is required to maintain the productivity of forest soils while forests continue to be managed for timber production. Although current regulations governing soil conservation in British Columbia are partially based on historic and ongoing research, there are few clear and unambiguous long-term results. The ne...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...

Western European coastal sand dunes are highly important for nature conservation. Communities of the creeping willow (Salix repens) represent one of the most characteristic and diverse vegetation types in the dunes. We report here the results of the first kingdom-wide fungal diversity assessment in S. repens coastal dune vegetation. We carried out massively parallel pyrosequencing of ITS rDNA f...

Global environmental changes affect not only the aboveground but also the belowground components of ecosystems. The effects of seasonal drought and air warming on the genus level richness of Collembola, and on the abundance and biomass of the community of Collembola and mites were studied in an acidic and a calcareous forest soil in a model oak-ecosystem experiment (the Querco experiment) at th...
