proposed integrated complex for delhi judicial academy

Rapid Environmental Impact Assessment (REIA) Study for Proposed Integrated Complex for Delhi Judicial Academy,
National Law School, and National Institute for Mediation & Conciliation at Dwarka, New Delhi
institutional. Within 1 Km radius of the proposed project site, many residential apartments
also exist. As there is requirement of substantial residential accommodation for the National Law
School as well as for the Delhi Judicial Academy, the Ministry of Urban Development after the
recommendation by DDA has issued a gazette notification to bifurcate the project site with
different land uses, namely Institutional and Residential. No agricultural and industrial areas exist
within the core zone of the proposed project site. The proposed project site is designated for the
intended purpose and the necessary change in the land use of the plot area measuring 23,180 sq.
meters (5.72 acres) has already been effected by converting it to land use for residential use from
land use for Government use in MPD-2001.
4.8.4 Soil Quality
The soils of the Delhi area are mostly light with subordinate amount of medium texture soils. The
light texture soils are represented by sandy, loamy, sand and sandy loam; whereas medium texture
soils are represented by loam silty loam.
Four locations within the core zone of the proposed project site have been identified for collection
of soil samples. The sampling locations, their distances and bearing from the proposed site are
listed in Table 4.10. Data collected for chemical characteristics of soils through select parameters
viz. pH, EC, soluble anions, cation and cation exchange capacity are presented in Table 4.11.
pH is an important parameter indicative of alkaline or acidic nature of soil. It greatly affects the
microbial population as well as solubility of metal ions and regulates nutrient availability.
Variations in the pH of the soil in the study area are found to be 7.1 to 7.9 thus conducive for
growth of plant.
Electrical conductivity, a measure of soluble salt in the soil is in the range of 0.25 to 0.38. The
important cations in the soil are calcium and magnesium. It is observed that calcium and
magnesium concentrations are in the ranges 0.42 to 0.56% and 0.39 to 0.65% respectively.
Chlorides are in the range of 0.008 to 0.012%. Variation in CEC of the study area was found in the
range of 35.7 - 46.2 meq/100g. The relationship of CEC with productivity and absorptivity is
shown in Table 4.12 and Table 4.13.
Fertility status of soil is presented in Table 4.14. Organic matter present in soil influences its
physical and chemical properties of soil and is responsible for stability of soil aggregates. Organic
matter of soil is found in the range 0.59 % to 0.75 % showed moderate fertility of the soil. The
presence of organic matter enhances the metabolic activities of soil affecting the nitrogen and
potash content of soil. The fertility status in respect of Nitrogen, P 2 O 5 & K 2 O shows Moderate
level of fertility, which indicates the supplementations of these fertilizers are required. This shows
that soil is moderately fertile in organic and nutrient content.
