Abstract

The study was conducted to investigate the long-term application of manures and fertilizers on soil chemical properties in the rhizosphere and bulk soil under field condition. The research was conducted at ZARS, GKVK, Bangalore. There were 10 treatments and replicated thrice in an RCBD design. The treatment contains different levels of organic manures like 5t, 10t, 12.5t, 15t, 17.5t and 20t fertilizers like 25%, 50%, 75% and 100%. Soil chemical properties viz., Organic carbon, Ammoniacal-nitrogen, Nitrate-nitrogen, Available nitrogen and Available phosphorus were analysed in different treatments and these were found to be significantly higher in the treatment with application of 20t of FYM ha-1 compared to recommended NPK alone.
