Proton NMR relaxometry as a useful tool to evaluate swelling processes in peat soils [PDF]

, 2010
Dramatic physical and physico-chemical changes in soil properties may arise due to temperature and moisture variations as well as swelling of soil organic matter (SOM) under constant conditions.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Relationship between soil nurient concentration and plant nutrient status

Agricultural and Food Science, 1974
Foliar diagnosis as a method for assessing the nutrient status in a grownig medium seems to be useful. It gives the relationship between the available soil nutrient concentration and the plant nutritional status. The proportionality factor (k).

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

JSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

TESTING POTATO COLLECTION SAMPLES FOR THE PRESENCE OF GENES FOR RESISTANCE TO PHYTOPATHOGENS BY MEANS OF DNA MARKERS

Вавиловский журнал генетики и селекции, 2018
The development of phytopathogen-resistant varieties is the most reliable and economic way to reduce potato yield losses. Breeding of such varieties is possible by using genetic sources of resistance. The use of DNA markers for identification of valuable
