The Abundance of Soil Microorganisms after Planting Rice with Different Fertilization Systems

Hadija ., Nurdin Dalya, Muhammad Jayadi, Marhamah Nadir


Soil microorganisms play a major role in soil properties both physical, chemical and biological. The level of intensive land management with high input in conventional farming systems, especially paddy fields using chemical fertilizers, superior seeds and chemical pesticides can significantly affect the population and composition of soil microorganisms. This study aims to analyze the abundance of microorganisms using different fertilization techniques, by using residues of rice straw and inorganic fertilizers. Both techniques are thought to affect the abundance of soil microorganisms. The research was carried out in Salasaee Village, Soil Biotechnology Laboratory and Soil Chemistry Laboratory of Hasanuddin University. The research method was carried out through a collection of soil samples, identification of morphology and Characteris of Physology and Biochemistry, data analysis was carried out by exploratory descriptive. Based on the results of highest abundance of microorganisms found in third location (LK3) with the organic fertilization system which is 742 x 10-6 Cfu / gram, and the lowest abundance is found in first location which is 178 x 106 while in second location with semiorganic system is 381 x 10- 6 Cfu / gram. Microorganisms abundance of organic fertilizing systems addresses higher yields of inorganic and semiorganic fertilization systems. These different fertilization techniques affect the abundance of soil microorganisms can be seen from the diversity of microorganisms in research location where the organic fertilizing system can maintain the abundance of microorganisms compared to inorganic fertilization systems.
