Buğday yetiştirilen koşullarda farklı mikroalg nokülasyonlarının toprağın mikrobiyal karbon, azot ve fosfor bağlanmasına katkısıt
Microalgae or cyanobacteria have long been explored regarding their plant promotion and soil actvity enhancement. However potential of algae in affecting soil microbial biomass is need to be explored. Therefore following study was carried out to evaluate the response of soil microbial biomass to applied algae with and witout different levels of conventional chemical fertilizers. The treatements consisted of three different algae strains named Bioalg-1, Bioalg-2 and Bioalg-3 at two different concentrations i.e. 0,01 g kg-1 and 0,04 g.kg-1. They were applied with or without recommended dose of fertilizer from DAP constituting a total of 14 treatments where first two treatments were control with no algae or fertilizer application and the second one was just recommended fertilizer. For better comparison of the results, 4 treatments separately i.e. just soil, just wheat, just fertilizer and wheat with fertilizer were also carried out and were harvested after one week and subjected to all the analysis. Parameters like pH, EC, organic matter, lime content, total and avaialable nitrogen, organic carbon, available phosphorus and aggregate stability were measured along with microbial biomass carbon, nitrogen and phosphorus. Results reveal that algae application in general effected pH, EC, total and avaialable nitrogen, and aggregate stability where most prominent effect of soil microbial biomass was observed. Bioalg-1 alone led the microbial biomass carbon content where interestingly highest microbial biomass nitrogen was observed in the chemical fertilizer pots. Microbial biomass phosphorus was also observed maximum in Bioalg-3 with fertilizer, yet it stands same with Bioalg-1 without fertilizer statistically. From the results, it can be concluded that application of algae can significantly enhance soil microbiologic properties and long term application can also enhance soil organic matter.
