AB  - Wind erosion is one of the main factors of soil degradation and air pollution in 
      arid and semi-arid regions. In this study we evaluated microbial-induced 
      carbonate precipitation (MICP) as an alternative soil conservation method against 
      wind erosion using sugar cane molasse and vinasse as growth substrates in 
      comparison to tryptic soy broth (TSB). The three substrates were applied in 
      laboratory tests with and without addition of MICP cementing solution (1 M urea 
      plus calcium chloride) to two sandy soils differing in calcium carbonate content. 
      The performance of MICP solution inoculated with a cultured urease-producing 
      strain of Sporosarcina pasteurii was compared to that of an autoclaved MICP 
      solution. For control we also performed a blank treatment without substrate, MICP 
      solution and inoculation. In addition to lab tests in which we determined the 
      effects of treatments on soil pH, electrical conductivity (EC), calcium carbonate 
      (CaCO(3)) content and surface penetration resistance, we performed wind tunnel 
      experiments to determine soil loss by deflation under different wind velocities. 
      Applying vinasse and molasse strongly increased soil CaCO(3) content and 
      penetration resistance, with and without addition of inoculated or non-inoculated 
      MICP solution. Vinasse generally had stronger effects than molasse, while TSB was 
      less effective, especially on penetration resistance. The addition of MICP 
      solution in most treatments did not enhance but rather decrease the substrate 
      effects. In the treatments with vinasse and molasse, increase in penetration 
      resistance translated into substantially decreased soil loss in the wind tunnel 
      tests, down to around one third of the loss in the blank treatment. In contrast, 
      soil loss substantially increased in the treatments with TSB, probably due to the 
      high input of sodium with this substrate. Our results show that molasse and, even 
      more, vinasse can have a strong soil stabilization effect against wind erosion, 
      which is primarily related to the formation of CaCO(3) content and does not 
      depend on additional amendments. Thus, these substrates have a great potential to 
      be used on their own as environmentally friendly and cost-effective amendments to 
      control wind erosion of bare sandy soils in arid environments.
