Abstract:

The laboratory experiment was conducted at Department of Soil Science and Agricultural Chemistry, Banaras Hindu University, Varanasi, Uttar Pradesh, India. In this experiment, the adsorption of nitrate onto soils of different cropping systems viz. rice-wheat(R-W), rice-vegetable (R-V), pulse-pulse (P-P) and sugarcane(S) was carried out in a batch equilibrium system. Surface soil samples were collected for adsorption study from each cropping system. Results showed that the adsorption isotherms were L- type (Langmuir type) in most of the soils. Adsorption data for soils were found to obey the Freundlich adsorption equation over the entire range of concentrations studied (50-300 mg NO3--N/L). In all the cases, the values of coefficient R2F were in the range of 0.71 to 0.99. Considering the KF values, the order adsorption of nitrate on surface soils was: P-P> R-W (Cholapur)> S> R-W (Pindra)>R-V. The surface soil adsorption capacities were comparatively higher in R-W and R-V cropping system areas. In comparatively to the different surfaces of adsorption on soils, contribution of organic matter was found very higher (2.22 to 4.31) in these soils.
