The mangroves of the Bay Islands accounting for 18% (383 km2) of the total Indian mangroves were adversely affected by the December 2004 tsunami. Changes in topography, salinity and massive water inflow have led to extensive soil degradation and associated nutrient losses in these mangroves. The major

Land degradation, subsistence farming with poor crop harvests and lack of employment opportunities has resulted in poverty in eastern ghats of Orissa. To avert the situation, IWDP and TDET watershed projects were implemented in Kokriguda watershed which represents the resource position of this tribal region, during 1997 to 2003.

An attempt was made to investigate the influence of different doses of nitrogen on growth and yield of pearlmillet under irrigated and non-irrigated in semi-arid region of Delhi with an aim to determine the optimum levels of N under two different moisture situations (irrigated and non-irrigated).

Soil-water is present in soil as film on the soil particles and in capillary form in soil pores. Soil water which moves slowly possesses potential energy which is due to position or internal condition. Soil water potential is influenced by different force fields: matric, osmotic, gravitational and pressure.

An investigation was conducted to evaluate the changes in soil quality over time under different systems of nutrient application in the erosion prone soils of rainfed areas of kandi belt of Jammu. The soils had been under three nutrient management systems, viz., nutrient application through inorganic, organic and integrated (organic+inorganic) sources for the last eight years.
