A field experiment was carried out to elucidate the effect of chicken manure (CM) and effective microorganisms (EM) on the yield of corn and chemical and microbial properties of acidic wetland soils. A split-split plot experimental design with three replications was used in this research. The main plot consisted of two types of soil. The sub-plot was for the application of CM, while the sub-sub plot was for the application of EM. Sweet corn seeds were planted and cultivated until harvest. Above ground plant biomass and round of the stem of an ear of corn were observed. Soil samples were taken and analyzed for chemical and microbial properties. The results showed that the interaction between soil types and CM application affected the corn yield, while EM had no effect. Similarly, the chemical and microbial characteristics of soils used were affected by soil type and the application of CM, while the effect of EM was not clear.

Cyanobacteria were among the pioneer organisms of the early earth. They first colonized bare rock and had a strong ability to proliferate in infertile substrates, such as volcanic ash, desert sand, and rock. Cyanobacteria store enormous amounts of essential nutrients and metabolites within their cytoplasm. Those that grow in arid lands can be a very potent source of organic matter and nutrients that can be used to counteract desertification. In this study, we explored the potentiality of cyanobacterial strains collected from several regions of Asia (7 strains), Africa (3 strains), and Japan (6 strains). Some of the soils had salinity levels greater than 5 dS m-1 and an alkaline pH of 8.3-9.2. Cyanobacterial strains were screened for their potential to survive in such arid soils by quantifying individual salinity tolerance, ability to fix N2 in a medium containing 0.1M NaCl, and rates of photosynthesis and growth. The inoculation effects on the chemical properties of Alashan soils of Inner Mongolia (China) were evaluated using AL-S and Tateyama cyanobacterial strains. The soil pH of the surface and subsurface layers indicated that these strains can decrease pH to levels that are conducive to plant growth. These cyanobacterial strains have potential as anti-desertification agents for the bioreclamation of arid soils.
