What is Evapotranspiration and What are the Various Methods of Evapotranspiration? {{ currentPage ? currentPage.title : "" }}

Evapotranspiration is the totalization of evaporation from the surface of the earth and transpiration from plants. The definition of evapotranspiration differs from resource to resource.

On some platforms, we can find out that evapotranspiration deals with the evaporation from the surface water bodies and oceans. 

After understanding all the definitions, scholars for readers can easily figure out that evapotranspiration is essential for maintaining the hydrological cycle of the earth.

There are various methods of evapotranspiration that scholars and researchers have to understand for working on their projects and for understanding the hydrological cycle and its process. Therefore, to offer guidance biotechnology assignment help experts have defined the four methods of evapotranspiration in the pointers noted-below.

Methods of Evapotranspiration


Lysimeters is the process of evapotranspiration in which crops are grown in a large container installed in the crop field and their water loss and gain levels are measured. In this method, researchers take care that the crop and soil conditions in the lysimeters are close to the conditions of the surrounding fields. The measurement in this process is done by waiting for the large containers through scales or floating the lysimeters in water.

Soil moisture depletion

The soil moisture depletion study is the method of evapotranspiration in which we find out the consumptive requirement of irrigation field crops produced evenly on the soil when the deepness of groundwater is in a way that it will not put any impact on the soil most effectuation in the root zone.

Field Experiment

In the field experiment, we focus on the computation of water provided to the farm and transformations in moisture content in the soil of the field that are sometimes more reliable for calculating water needs of crops than computation with lysimeters that have limitations. The formula that we need to apply for this method is formed by amalgamating the quantities of seasonal irrigation water, the effect of rainfall in a particular season and the input of moisture from the soil. It can be expressed as -


Water Balance Method

This method is appropriate for watersheds for large areas over a long duration. This method of evapotranspiration can be expressed through the below noted hydrological equation.

Precipitation = evapotranspiration + surface runoff + sub-surface drainage + change in soil water contents

In this method, we need to do enough computation of all the factors, apart from evapotranspiration. The water balance method is also termed as the inflow-outflow method.

These are the four crucial methods of evapotranspiration. Along with understanding these methods and their uses, scholars learning biotechnology have to learn a lot more. They have to work on different academic projects that sometimes become highly challenging for them.

So, eliminate assessment pressure learners hire experts for availing biotechnology assignment help. The assignment help providers who guide scholars are associated with academic help brands. You can reach out to these experts anytime as per your academic requirements.
