Effect of microorganism inoculants on manure composting for tobacco planting.

The effects of microorganism inoculants application on index of composting were studied in present paper.The results showed composting temperature increased at first(50℃)and then decreased with the application of microorganism inoculants,wherase composting temperature of conventional composting changed little.The decay degree in composting materials,the reduction of carbon/nitrogen ratio,the addition of NO+3-N content,the increase of humus index and seed germination index were strengthened by the application of microorganism inoculants.Manure composting could reach the requirement of fertilize after 28 days of the composting period when applying the microorganism inoculants.The application of microorganism inoculants could improve the composting process and its quality.
