Abiotic factors and application of organic manures influence activity of soil organisms. A field experiment was carried out at the Zonal Agriculture Research Station, UAS Bengaluru during 2014-15. There were ten treatments with varying combinations of FYM (0-20 t/ha, partially decomposed, with Glyricidia mulch) and conventional fertilizers (0, 25, 50, 75 and 100 % of 100:50:25 kg NPK /ha). Fodder maize was grown in this 13 years old plot during kharif season. Soil samples were drawn to extract meso-fauna from before application of treatments up to 300 days after germination. The results indicated that there was a significant relationship existed between the abundance of soil meso-fauna and abiotic factors. Sunshine hours and minimum temperature of the soil showed significant negative correlation with soil meso-fauna. Maximum and minimum relative humidity, total rainfall and Insitu soil moisture had significant positive correlation. The contribution of abiotic factors on the abundance of soil meso-fauna was 31.9 per cent. The influence of minimum relative humidity on the abundance of soil meso-fauna was up to 28.3 per cent. Abiotic factors like rainfall and soil moisture are known to have marked influence on soil organisms. Distribution of rainfall had significant influence on the abundance of soil meso-fauna.
