Effects of different modes, levels of farmyard manure and fertilizer nitrogen applications on soil properties: A long term study
Author(s): Deepika, Manoj Kumar Sharma and Devraj
Abstract: A long term field experiment started in 1967 was selected to study the effect of modes and levels of FYM as well as levels of fertilizer N on soil properties. After 50 years of experiment, results shows that soil pH of all the plots decreased as compared to initial value. However, soil EC, showed the reverse trends. Application of FYM in both the seasons (kharif and rabi) significantly improved the SOC, available N, P an K content in soils as compared to its application in single season (kharif or rabi). It was also observed that irrespective of mode of application, addition of 15 t/ha FYM showed superiority over lower doses as far as soil health was concerned. Furthermore, application of fertilizer N in combination with FYM resulted in higher values of SOC, available N and P, but available potassium content decreased with increased doses of N fertilizer alone.
