A diagnostic survey was conducted in rice-wheat and maize-wheat blocks of Bulandshahr district for identification of tillage and other related soil physical constraints in farmers' fields.

Twenty water samples of Chenab, Ramban area were analysed for Ca, Mg, K, Na, Fe, Mn, Cu, Ni, Zn and Pb by Atomic Absorption Spectrophotometry. The analysis revealed that all the cations are present within the permissible limits except Fe, Mn and Ni which are slightly present in higher concentrations.

A Decision Support System (DSS)on bio-drainage for reclamation of salt affected and waterlogged lands was developed using Visual Basic (VB) protocols. The DSS permits the user to interactively enter input information viz., the area available for plantation, average annual rainfall, initial and desired water table depth, soil type and the plantation type.

A decision support system was developed for reclamation and management of alkali soils. The decision support system identified different reclamation and management techniques as land levelling, gypsum requirement and its addition, cultivation of tolerant crops, cultural practices, afforestation, groundwater recharge, groundwater use and surface drainage.

Following the success of watershed development operation research project Sukhomajri in Haryana, large number of water harvesting dams were constructed in the Shivaliks region of north India. The reservoirs of a number of these earthen dams got silted due to fragile geological strata, inadequate vegetation cover in the catchment areas, continued biotic interference and lack of community participation in building social pressure against grazing and illicit felling.

During the earliers days, hilly villages used to have their own ponds, which served the community. The ponds were desilted by the community. But over the period of time, bond of the villagers over such common property is getting weak.

A field experiment under runoff plots was conducted at Devala, Gudallur taluk of the Nilgiris from 2001 to 2003 to evaluate the impact of vegetative barriers and mechanical measures on erosion losses on 25 per cent sloping land under cultivation of cassava.

In India, chemical degradation of lands is taking place at an annual rate of 0.15-Mha. This is about 10 per cent of the annual global rate of about 1.5-Mha. Due to this, about 3.22 per cent of land area in the country has already become salt affected. Literature search reveals that a myriad of experiments for assessing impacts of varied land/water management strategies on the root zone soil salinization and crop yield reductions have been conducted for managing salt affected lands of India.

Poor management of irrigation water and inadequate drainage system in plains have made vast tracts of agricultural land unproductive due to waterlogging and high moisture content. Integrated development of such waterlogged ecosystem has been taken up under NWDPRA (National Watershed Develpoment Project for Rainfed Areas) with the twin objectives of sustainable production of food, fruit, fuel and bio-mass and restoration of ecological balances with the watershed.
