Effect of Ceramsite Mulching on Soil Water Content and Temperature

Article Preview

Abstract:

This study investigated the effects of ceramsite mulching on soil water content and temperature in the central isolation belt of an expressway in Hebei province, China. Ceramsite mulching effectively improved the soil water content, and reduced the disparity between different soil layers in different months. The order of soil water content at different soil depths or in different months was: two layers of mulching (M2) > one layer of mulching (M1) > bare soil (MD). The effect of ceramsite mulching on soil water content decreased with soil depth. The effect of ceramsite mulching on soil temperature decreased with soil depth from 0cm to 15cm. ceramsite mulching had a cooling effect above 5cm,but had a heating effect at 15cm.M2 balanced soil temperature better than M1.
