Modeling of Evaporation from Bare Soil

In the era of global climate change and consequently the reducing moisture availability, the knowledge of bare soil evaporation is of paramount importance for planning and executing agricultural operations for growing crops. In India too, this phenomenon has got special significance as during the summer season large barren tracts experience intense heat and wind, resulting into a completely dry soil profile. The climatic water demands remains quite high even with the onset of monsoon for few days so much so that almost whole amount of first rain gets soaked and redistributed into the soil profile. Subsequently, this moisture gets evaporated and lost without any beneficial use. A quantitative assessment of bare soil evaporation from the agricultural lands will help the planners to design appropriate strategies for land preparation, sowing and growing crops with less or limited water supply situations.
