Do freeze-thaw events enhance C andN losses from soils of different ecosystems? A review
Freezing and thawing of soils may affect the turnover of soil organic matter and thus the losses of C and N from soils. Here we review the literature with special focus on: (i) the mechanisms involved, (ii) the effects of freezing temperature and frequency, (iii) the differences between arable soils and soils under natural vegetation, and (iv) the hypothesis that freeze-thaw events lead to sign...
متن کاملStability of Ion Exchange Resin Under Freeze–Thaw or Dry–Wet Environment
reduced adsorption of NO3–N and NH4–N by anionic and cationic resins, respectively. Kjonaas (1999) also Ion exchange resins have widely been used in mineralization studies observed no detectable effect of freezing on resin staof organic materials. However, the stability of resin (anionic and cationic) under changing physical environmental conditions is not bility. Lehmann et al. (2001) have obs...
متن کاملSimulating Martian Conditions: Methanogen Survivability during Freeze-thaw Cycles
Introduction: Methanogens are obligate anaerobes that use molecular hydrogen as an energy source and carbon dioxide as a carbon source to produce methane. They are classified as Archaea and are found in many extreme environments, including hydrothermal vents, volcanoes, and also the human microflora. The current Martian atmosphere is low in pressure, very dry (hyper-arid), and high in radiation...
متن کاملDry–wet Cycles Increase Pesticide Residue Release from Soil
Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9-17 years) (14) C-labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide...
متن کاملFreeze-thaw effects on phosphorus loss in runoff from manured and catch-cropped soils.
Concern over nonpoint source P losses from agricultural lands to surface waters in frigid climates has focused attention on the role of freezing and thawing on P loss from catch crops (cover crops). This study evaluated the effect of freezing and thawing on the fate of P in bare soils, soils mixed with dairy manure, and soils with an established catch crop of annual ryegrass (Lolium multiflorum...
