Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...

To evaluate the effect of gypsum and manure on the yield and quality of sugarcane and properties of sodic soils, an experiment was conducted on farmer’s field at Dosehra area, District Charsadda during Kharif 2004. Ten treatments comprised of control (T1), gypsum @ 25 % of the soil requirement (T2), gypsum @ 50 % (T3), gypsum @ 75 % (T4), gypsum @ 100 % (T5), farm yard manure (FYM) @ 20 tons ha...

The salinization of soil is responsible for the reduction in growth and development plants. As global population increases day by day, there a decrease cultivation farmland due to soil, which threatens food security. Salt-affected soils occur all over world, especially arid semi-arid regions. total area salt-affected 1 billion ha, India, an nearly 6.74 million ha?1 salt-stressed, out 2.95 are s...

The area of salt-affected soils is increasing globally, mainly due to land use and management malpractices, which can threaten soil health the sustainability farms. Climate change likely increase prevalence in many agricultural areas increased aridity and, coastal areas, sea water level. causes processes that develop are diverse result salinity, sodicity, alkalinity, or a combination these cond...

Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...

To use of organic fertilizer sources for increasing crops production on sustainable basis has become imperative because the cost of chemical fertilizers is high. An experiment was conducted during 2006 on two saltaffected soils of District Charsadda to evaluate the effect of different levels of single super phosphate (SSP) alone and in combination with humic acid (HA) on phosphorus availability...
