| Abstract: | The effect of freezing and thawing is a non-biological effect that exists in soil.It is the most common phenomenon in nature.It has effects on the physical,chemical and biological characteristics of soil.The effects of freezing and thawing on the stability of soil aggregates,the discharge of greenhouse gas,nutrient content and availability,microbial biomass and vitality were reviewed.The effect of freezing and thawing on the soil enzyme activity and nutrient availability would be the focus in future studies. |
