Abstract:
A field experiment was conducted to evaluate the effect of biochar with various sources of
organic manures on soil organic matter and bulk density at Jamuniya-1, Nawalparasi from
October 2015 to January 2016. The experiment was laid out in a Randomized Complete Block
Design (RCBD) with 10 treatments i.e Control, biochar (100%), FYM (100 %), poultry manure
(100%), vermicompost (100 %), biofertilizer (100%), biochar (50%) +FYM (50%), biochar
(50%) + poultry manure (50 %), biochar (50%) + vermicompost (50 %), biochar (50%) +
biofertilizer (50 %) replicated 3 times. Biochar was prepared from locally available rice husk
under pyrolytic condition and applied in field together with other organic amendments before 15
days of transplanting of cabbage seedlings. Analysis of primary nutrients of the organic manure
and biochar was done and rate of manure was fixed on the basis of their nutrient content. Biochar
applied with organic manures significantly increased the soil water holding capacity and reduced
the soil bulk density. This study showed that organic manure applied with biochar improved the
soil physical properties as compared to control. Biochar application provides an innovative
method for handling excess organic wastes to sequester carbon and to improve soil health and
plant productivity. |
