Measurement of soil moisture is necessary in several soil and hydrological investigations. Soil moisture measurements are needed for scheduling irrigations, in experimental studies on crop water requirements and evaluating surface irrigation systems. Soil moisture measurements are also needed in areas of less rainfall for evaluating different moisture conservation practices. There are many methods available for measuring soil moisture. Most of [...]

Acid Sulphate Soils. Introduction to Salt Affected Soils: High concentrations of certain salts when present in the soil cause soil and water management problems and ultimately affect crop [...]
The upper reaches of a watershed usually consist of hilly areas. These areas have an undulating topography and are foci for soil erosion. In areas with steep slopes and subjected to soil erosion vegetation do not get established. Due to lack of vegetative cover soil erosion is accelerated transporting large quantities of silt into the streams below. The uncontrolled runoff [...]
