The main objective of agricultural applications using intensive chemical fertilizers is to guarantee high yield and quality. But these applications are costly and cause environmental problems. For these reasons, there has recently been increased interest in environmental friendly, sustainable and organic farming practices. In this study was to evaluate and compare the cost of different microbial bio-fertilizers, commercial organic fertilizer and chemical fertilizer treatments, applied on rangeland in Erzurum, Turkey. A total of 22 different applications were evaluated for the economic analysis of plant nutrient applications from different sources in natural rangeland conditions in Erzurum province. As an alternative for chemical and commercial organic fertilizer applications, only the subjects that 5 different bacteria replaced with reduced fertilizer doses. As a result of the study, half-dose nitrogen + Pseudomonas fluorescens T26 treatment and half-dose nitrogen + half dose Phosphorus + Paenibacillus polymyxa TV-12E can be recommended in terms of economical. In rangelands, bacterial applications will provide yield increase, and also protects the underground water and soil resources against nitrate pollution.
