Soil water wetness, also known as soil moisture content, refers to the amount of water held in the soil between soil particles. It is a crucial factor for plant growth, impacting various processes like nutrient uptake, photosynthesis, and transpiration. Measuring soil water wetness is essential for farmers, water resource managers, and researchers to make informed decisions about irrigation, water conservation, and agricultural practices. Generally, soil water is studied in three forms, such as – Surface Soil Wetness (surface to 5 cm below), Root Zone Soil Wetness (surface to 100 cm below) and Profile Soil Moisture (surface to bedrock). in the research paper presented by the researcher, the amount of water present in the soil of Bikaner district located in the Thar Desert of Rajasthan has been analyzed on the basis of data from the year 1981 to 2022.Surface Soil Wetness, Root Zone Soil Wetness and Profile Soil Moisture in the period from 1981 to 2022. The quantity has to be analyzed on a time basis. It is clear from this study that there has been a substantial increase in the amount of middle soil water in the study area Bikaner district from the year 1981 to 2022. The main reason for which is the increase in the area irrigated by tube wells, rain water harvesting, tree plantation, increase in irregular rainfall and slight decrease in temperature.
