Effect of freezing and thawing processes on some physical properties of saline–sodic soils mixed with sewage sludge or fly ash

The changes in the physical and hydraulic properties of a loamy soil under irrigation with simpler-reclaimed wastewaters

“…Aggregation and therefore soil structure may be either positively or negatively affected by freeze-thaw cycles (Sahin et al, 2008). Therefore, the impacts of wastewater irrigation on main soil properties in agricultural areas under cool climate conditions may be different.…”

The influence of different tillage practices on water content of soil and crop yield in vetch–winter wheat rotation compared to fallow–winter wheat rotation in a high altitude and cool climate

“…Surface soil layers are exposed to freeze-thaw cycles, especially in the spring period. Freeze-thaw cycles in cooler climates may positively or negatively affect soil aggregation and the structure (Sahin et al, 2008). Moreover, decomposition rates of soil organic matter in cooler climates are slow (Várallyay, 2010).…”

Interaction between Soil Physicochemical Parameters and Earthworm Communities in Irrigated Areas with Natural Water and Wastewaters

“…In the regions with a cool climate, soils are exposed to freeze-thaw cycles, especially in the spring period. Aggregation and therefore soil structure may be either positively or negatively affected by freeze-thaw cycles [61]. Therefore, the impacts of wastewater irrigation on main soil properties in agricultural areas under cool climate conditions may be different.…”
