Salient Characteristics of Cultivated Soil Influenced by Legume and Cereal Cropping System

I.A. Mahmood and M. Aslam    

Abstract: Soil Nitrogen and Organic Matter were determined before sowing and after the harvest of crops to assess the effect of wheat and chickpea growth on soil fertility. Chickpea crop utilized less soil N and NO3-N as compared to other crops even when nitrogen was applied but it caused a significant increase of nitrogen and organic matter in soil whereas wheat exhausted the nutrients. The total N and NO3-N level in the soil fell down much more in case of wheat cultivated without N application. The control treatment showed a slight fluctuation in measured parameters. Organic matter of the soil was ameliorated by crops grown over the season comparatively better by chickpea crop.
