N2 - In the last few decades, Bengaluru’s rapid urban expansion and associated population growth brought about profound changes in farming practices, reflected in an increase in irrigated land compared to rainfed land and a growing use of mineral fertilizers. Since it is not clear how intensification of land use due to urbanisation is affecting physical soil properties and field water cycle, we attempt to clarify this at two experimental sites established at the University of Agricultural Sciences Bangalore (UASB). The results show higher bulk densities, lower air capacities, and lower saturated hydraulic conductivity (Ksat) values in the rainfed field compared to the irrigated field. Soil moisture was observed to be higher in deeper layers of several plots with low N-level treatments in both experiments. However, it was not significant in other plots. Further statistical investigations and comparisons especially of model simulations are required to assess the effect of land use intensifications. Here the experimental approach and some preliminary results are presented.
