Abstract

In recent years, georeferenced soil information system has gained significance in agricultural land-use planning and monitoring the changes in soil properties/ soil quality induced by land-use changes. The spatiotemporal information on saturated hydraulic conductivity (sHC) and soil water retention-release behaviour is essential for proper crop and land-use planning. The sHC greatly influences the drainage process and soil water retention-release behaviour, ultimately affecting the crop growth and yield. However, sHC and water retention are not measured in a routine soil survey and are generally estimated from easily measurable soil parameters through pedotransfer functions (PTFs). In the present study, PTFs for sHC and water retention were developed separately for the soils of two food-growing zones of India (the Indo-Gangetic Plains (IGP) and the black soil region (BSR)). For the IGP soils, sHC is affected by the increased subsoil bulk density due to intensive cultivation. In BSR, presence of Na⁺ and Mg⁺⁺ ions affects the drainage and water retention of the soils. Therefore, these soil parameters were considered while developing the PTFs using stepwise regression technique in SPSS. The validation of PTFs was found to be satisfactory with low RMSE values and high model efficiency.

Abstract

Current status of land/soil resources of the Indo- Gangetic Plains (IGP) is analysed to highlight the issues that need to be tackled in near future for sustained agricultural productivity. There are intraregional variations in soil properties, cropping systems; status of land usage, groundwater utilization and irrigation development which vary across the subregions besides demographies. Framework for land use policy is suggested that includes acquisition of farm-level data, detailing capability of each unit to support a chosen land use, assess infrastructural support required to meet the projected challenges and finally develop skilled manpower to effectively monitor the dynamics of land use changes.

Abstract

Sustaining soil and land quality under intensive land use and fast economic development is a major challenge for improving crop productivity in the developing world. Assessment of soil and land quality indicators is necessary to evaluate the degradation status and changing trends of different land use and management interventions. During the last four decades, the Indo-Gangetic Plains (IGP) which covers an area of about 52.01 m ha has been the major food producing region of the country. However at present, the yield of crops in IGP has stagnated; one of the major reasons being deterioration of soil and land quality. The present article deals with the estimation of soil and land quality indicators of IGP, so that, proper soil and land management measures can be taken up to restore and improve the soil health. Use of principal component analysis is detailed to derive the minimum dataset or indicators for soil quality. The article also describes spatial distribution of soil and land quality with respect to major crops of IGP.

Abstract

To meet the demand of food, fodder, fuel and fibre for the ever-increasing population of the world, achieving higher land and water productivity of a parcel of land is a major challenge. For this, site-specific cropping system plan and land-use system based on basic soil and terrain information are a prerequisite. With the advent of remote sensing and geospatial technique, collection of point data and their spatial interpolation on watershed basis is possible in quick time, which can be used for site-specific cropping system planning. In this study, site-specific cropping system and profitable land-use plan were prepared for a watershed of eastern India (Darpanarayanpur, Nayagarh district, Odisha) using geospatial technique. Drainage analysis revealed that prominent drainage pattern was dendritic with low drainage density which indicates that the watershed region has subsoil with high permeability and low relief and, accordingly, rainwater harvesting structures have been suggested in the watershed.
