Soil endowments, production technologies and missing women in India - A World Bank working paper

This paper published by the World Bank highlights the findings of a study that aimed at exploring the connections between geographical variation in soil texture and rural infant sex ratios in India. The paper argues that the deficit of women relative to men in some societies has emerged as the most extreme indicator of gender-based discrimination. Studies concerned with the demographic gender imbalance have provided evidence on significant effects of economic factors and of cultural disparities in the perception of women’s worth. However, there are very few studies that have tried to explain the geographical differences in population sex ratios.Read More

Soil physio-chemical properties of Basantar catchment in Jammu and Kashmir – A research report by National Institute of Hydrology

The report presents the study on the physio-chemical properties of soil for Basantar catchment in Jammu and Kashmir. Soil physio-chemical properties are basic inputs for any hydrological modeling and are important for efficient management of irrigated agriculture. The most important soil properties influencing irrigation are its infiltration characteristics and water holding capacity. Other soil properties such as soil texture, soil structure, capillary conductivity, soil profile conditions, and depth of water table are also given consideration in the management of irrigation water.Read More

Soil classification of Dudhnai representative basin (Assam and Meghalaya) - A research report by National Institute of Hydrology

The study attempts to do field and laboratory determination of soil classification properties in the Dudhnai river basin of Assam and Meghalaya. Point infiltration tests using double ring infiltrometer were conducted at various locations (forty-four sites) in respect of different land use conditions. Soil samples were collected from these infiltration testing sites.

The saturated hydraulic conductivity was determined in the field using Guelph Permeameter for the selected sites. The undisturbed soil samples and disturbed soil samples (50 cm below the ground) were collected and subjected to elaborate laboratory tests. Read More

Determination of hydraulic conductivity of soils in Central Bihar - A research report by the National Institute of Hydrology

The study gives a systematic methodology to determine field hydraulic conductivity using Guelph Permeameter (GP), its limitation based on the experiences gained in the field and a comparison of its results with that estimated from the predictive method for the soils in Central Bihar. Predictive methods applying empirical formulae are used to ascertain hydraulic conductivity from easily determined factors like bulk density, porosity and water content.

Physically based hydrological models, soil water balance, groundwater flow and transport models require values of saturated and unsaturated hydraulic conductivity to solve the sub-surface flow and transport equations. Several field, laboratory and predictive methods are available for determination of this parameter. However, these methods have some advantages and some limitations. GP is used as a tool to determine the field hydraulic conductivity even when the water table is low. It is portable, durable and allows rapid field calculation of saturated and unsaturated hydraulic conductivity.Read More
