The field investigations were carried out on sandy loam soil at the research farm, Department of Agricultural Meteorology, Punjab Agricultural University, Ludhiana during rabi 2006-07 and 2007-08. Wheat is the premier cereal crop during rabi season in Punjab. In 2008-09, it was grown on 35.26 lac tonnes and per hectare yield of 44.62 quintals. Wheat needs cool climate during early part of its growth and warm temperature at this stage is unfavourable for tillering and promotes several diseases.

An experiment was conducted to study the phosphate adsorption-desorption behaviour of some paddy growing soils of Anantnag district of Kashmir. Representative soil samples (0-15 cm) were collected from thirteen locations of district under paddy.

The growth and plant water relations of Eucalyptus tereticornis Sm. and E. camaldulensis Dehnh. in relation to soil salinity were studied by transplanting one and half month old seedlings in the pots filled with eight levels of artificially created soil salinity levels.

Infiltration tests were conducted at three locations in the Pooppara Tribal Colony area, Idukki District, Kerala. Physico-chemical analysis of the soil samples shows that the soil type for the selected locations is sandy clay loam and is acidic in nature with low bio-manure.

Rain is the only source of water on the earth and for conserving this precious resource, the base is the land. Shortage of rainfall coupled with its erratic distribution during rainy season causes severe water deficit conditions resulting in various intensities of droughts. Drought varies in different parts of the world depending on the amount and reliability of rainfall received in a particular region. Gulbarga district is one of the drought prone districts of the Karnataka state.

Investigations and experience on truth of natural plant life surrounding us revealed that 1) soil is living, 2) health of cattle influences biodiversity as well as recycling of biomass and 3) quality of water. It is "soul" content of alternate farming.

Fossil fuel combustion and fertilizer application in the United States have substantially altered the nitrogen cycle, with serious effects on climate change. The climate effects can be short-lived, by impacting the chemistry of the atmosphere, or long-lived, by altering ecosystem greenhouse gas fluxes. Here we develop a coherent framework for assessing the climate change impacts of US reactive nitrogen emissions, including oxides of nitrogen, ammonia, and nitrous oxide (N2O).
