Effects of rates and time of zeolite application on controlling runoff generation and soil loss from a soil subjected to a freeze-thaw cycle
Many factors such as freeze-thaw (FT) cycle influence soil behavior. Application of soil amendments can play an important role on runoff time commencement (RT), volume (RV) and soil loss (SL) on soils subjected to FT cycles. However, limited studies have been documented on this subject. The present...

| description | Many factors such as freeze-thaw (FT) cycle influence soil behavior. Application of soil amendments can play an important role on runoff time commencement (RT), volume (RV) and soil loss (SL) on soils subjected to FT cycles. However, limited studies have been documented on this subject. The present study was therefore carried out under rainfall simulation circumstances to investigate the effect of different rates of zeolite application to control the effects of FT on basic hydrological variables such as runoff production and soil loss. Towards this attempt, the effect of application of different rates of 250, 500 and 750 g m−2 of zeolite applied before, during and after the occurrence of FT cycle on RT, RV and SL was assessed in a completely randomized design. Treatments were set up in two categories viz. control (without zeolite application), and three rates and times of zeolite application in small 0.25 m2-experimental plots in three replications. The results showed that application of zeolite had significant effects on hydrological behavior of soil induced by FT cycles. Application rate of 750 g m−2 prior to FT cycle increased RT and reduced RV and SL at rates of 644%, 68% and 91%, respectively. The results also verified that zeolite could successfully mitigate the impacts of FT cycle on the main soil hydrological variables of soil profile induced by FT cycle. It is accordingly recommended to employ zeolite as an effective amendment to control soil erosion in steep and degraded rangelands where surface soil is exposed to rainfall and runoff. |
