Abstract:
The present investigation entitled “Quantification of heavy metals concentration in long term fertilizer experiment under rice-wheat cropping system on Vertisol” during the kharif and rabi seasons of 2018-19 and 2019-20 at research farm of College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The objective of the study were to determine cadmium, cobalt, nickel, lead and chromium content in soil under long-term application of inorganic fertilizer applied plots. The experiment was laid in a Randomized Block Design with ten treatments i.e. T1-Control, T2-50% NPK, T3-100% NPK, T4-150% NPK, T5-100% NPK+Zn, T6-100% NP-K, T7-100% N-PK, T8-100% NPK+FYM (5 t ha-1), T9-50% NPK+BGA (10 kg ha-1), T10-50% NPK+GM (Sunhemp). The above treatments were randomized with three replications. The experimental soil was Vertisol, locally called as kanhar. It is dark brown to black in colour, deep, heavy clay (50%) and neutral to alkaline in the reaction due the to presence of lime concentration.

The above treatments were randomized with three replications. The experimental soil was Vertisol, locally called as kanhar. It is dark brown to black in colour, deep, heavy clay (50%) and neutral to alkaline in the reaction due the to presence of lime concentration.
The AICRP on long-term fertilizer experiment was initiated in the year 1999-2000 at Raipur (C.G.) and after two decades of study indicated that phosphatic fertilizers like single super phosphate derived from the phosphatic rocks were the chief sources of heavy metals like cadmium and lead. Results showed that cadmium, cobalt, nickel, lead and chromium content in soil were at par amongst graded doses of inorganic fertilizer application (50, 100 and 150% NPK) as well as in integrated nutrient management (FYM, BGA and GM) practices. It can be concluded from the study that all the available heavy metals content in different treatments was higher in surface than the subsurface soil in all the treatments. The heavy metals content found in rice and wheat in soil under safe and within the maximum permissible limit as reported by WHO.
