Compatibility and survival of beneficial microorganisms for agricultural use (Beauveria bassiana, Paecilomyces lilacinus and Bacillus thuringiensis) in compost

Compatibility and survivorship of beneficial microorganism in compost were evaluated in order to provide new alternatives to clean production in agriculture. The study was conducted at the Ecological Farm belonging to the Consejo Provincial de Tungurahua, Ecuador. Four treatments were considered related to dose of several beneficial microorganisms (EMs). After an interval of 30 or 60 days after composting process, analysis of nutritional biological content showed compatibility and survivorship of the EMs, which live together and reproduce on the organic fertilizer. Concerning physic-chemical analysis higher organic matter content, pH, electrical conductivity, nitrogen, phosphorous, potassium and calcium were evidenced in T1: 100 cc Beauveria bassiana - 100 cc Bacillus thuringiensis - 100 cc Paecilomyces lilacinus. From the results obtained will offer the possibility of using beneficial microorganisms to optimize their performance in obtaining compost of better nutritional and biological quality, so that gradually reduce the use of agrochemicals.
