The brush straw checkerboard barrier offers a novel approach to sand
control and features 60% higher design efficiency and a longer lifespan
of 6 years compared to the traditional artificial straw checkerboard
barrier. The wind tunnel test and field observation confirmed that the
brush straw checkerboard barrier has high sand fixation efficiency. But
how do these two sand barriers perform in terms of restoring soil
function? How does the effectiveness of restoring soil function change
as the service life of the straw checkerboard barrier increases? These
questions still need to be clarified further. This study, conducted in
Zhongwei, Ningxia, China, examined plots with brush straw checkerboard
barrier, artificial straw checkerboard barrier, and bare sand. The
results show that the brush straw checkerboard barrier is superior in
improving soil moisture, organic matter, total nitrogen and electrical
conductivity compared to the artificial straw checkerboard barrier. In
addition, the brush straw checkerboard barrier has a positive impact on
microbial diversity and community composition. Increasing sand fixation
year through the brush straw checkerboard barrier correlates with
improved soil properties and microbial indexes, suggesting that it has
the potential for widespread application in desertification mitigation.26 Aug 2024Submitted to Land Degradation & Development 27 Aug 2024Submission Checks Completed
