Microalgal biomass is utilized in many fields such as food, agriculture, energy, and cosmetic sectors. It is very well known that chemical fertilizer adversely affect soil, plant, and environment. To reduce this effect in recent years, interest to organic farming has been increasing. In this study, microbial fertilizers obtained from microalgae was applied to maize and wheat plants. Microbial fertilizers at four different doses were applied, namely, S1 (control: 0,00 dose-non fertilizer), S2 (0.50 dose), S3 (1.00 dose), and S4 (1.50 dose). All measurements were made at the end of 30th days. The best results were determined for S3 dose applications. During the experiment, the soil temperature between 15 and 30 degrees C and soil pH values between 6.5 and 8.5 were maintained. The results showed that the amount of soil organic matter and the water holding capacity were improved. Finally, microbial fertilizers obtained from microalgae can be reported to have positive effects on soil, plants and therefore environment.
