Introduction
This study is based on types of levelling in agricultural engineering. Levelling suggests the procedure of searching for various elevations among two or more two aspects in the agricultural aspects. Through the process of levelling an individual can take the reading of the tests. Levelling in the agricultural aspect includes differentiation in these aspects; it majorly suggests making variation among the types of levelling. This process of levelling is an integral part of agricultural science because through this process the sample can be detected in the proper way for the test.
In the case of agricultural engineering, there are eight types of levelling as “different levelling”, “check levelling”, “profile levelling”, “cross-sectioning”, “reciprocal levelling”, “barometric levelling”, “hypsometry”, and “trigonometric levelling”.
“Different levelling”
This levelling is considered the operational method of levelling. Through this kind of levelling the “elevation of the points” are conducted. Through this type of levelling the distances can be measured or the part of benchmark related to the agricultural aspect can be taken.
“Check levelling”
This levelling can be conducted regarding the activities of the running levels to check the lists of levels and these levels or series have been previously determined. After the work of every day in agriculture, the level line has been kept and the individual returns to the beginning part and detect the work process regarding this type of levelling.
“Profile levelling”
Through this levelling, the object has been detected regarding the “elevation of the points”. In this regard, the distance and the level become the major part. This levelling is helpful to get an accurate outline about the outline or the reality of the ground. Most importantly, “profile levelling” is also known as “longitudinal levelling” or “sectioning”.
“Cross-sectioning”
Through the process of “cross-sectioning”, the surface of the test can be measured or through this process, the transverse of the ground has been measured. Most importantly, this process can happen only to the given line or the area of the line of this process.
“Reciprocal levelling”
“Reciprocal levelling” helps an individual to make differentiation among the elevation of the two points. It can be said that through this levelling the two types of observation can be differentiated minutely and accurately. This process is only applicable when there is no possibility to fix the level among the two points in the midway.
“Barometric levelling”
Through “Barometric levelling”, the altitudes of the various points agave been detected. This detection can be conducted through the use of a barometer. Through this levelling, the pressure of the atmosphere can be measured.
“Hypsometry”
It is another process of levelling in that the heights of hills or the mountains can be measured through the detection of the temperature and most importantly, this temperature has been taken to the level at which the water boils.
“Trigonometric levelling”
“Trigonometric levelling” is another procedure of the levelling of the agricultural aspects in that the “elevation of the points” has been measured or computed in the perspective of the “vertical”, “angles”, and “horizontal” positions and also these measurements can be conducted in the perspective of the agriculture in the fields.
There is another concept of levelling that is when the level can be fixed accordingly and in the right way, the lines have been in the horizontal position. In the case of the rotation of the telescope along with the vertical axis, this has been rotated in the horizontal platform and this horizontal platform is also called “collimation”. Through this process, the readings have been taken with the help of the telescope. In that, the vertical points of view are set up downwards from the plane. In this aspect, there are two vital parts rearing levelling like
- To detect the “elevation” or “R.L” of “collimation” regarding the level through the process of taking back about the benchmark
- To detect the “levitation of R.L” of the various aspects through the measurement of the readings on the points which have been selected previously.
Conclusion
This study mainly focuses on the various types of levelling which are necessary in the case of agricultural engineering. The types of levelling are also helpful for the sample of the test. Based on the levelling, an individual can measure the sample or the test. In this regard, it can be said that there is an integral part of the land levelling, which help to detect the condition of the land regarding the production of the crops. Not only has that but also through the land levelling, the needs or the requirements of the water which is required for the land been measured.
