Abstract:
The effect of organic and inorganic fertilization on labile carbon fraction in an typic Haplustepts soil of Southern Rajasthan (India) was studied in a long-term field experiment initiated during 1996-97 at Instructional farm, Rajasthan College of Agriculture, Udaipur (India). Labile organic matter fraction (i.e WS-OC, WS-CHO, KMnO₄, POC and LFOC) were significantly influenced by organic and inorganic fertilization. Significantly highest value of all labile matter fraction were recorded under FYM @ 20 t ha^-1 treatment followed by 100% NPK + FYM 10 t ha^-1 treatment. Balance use of fertilizers alone or in combination with organic manure resulted in significant build up of available N and P.
